WARNING
Hazardous voltages may be present when covers are removed. Qualified
personnel must use extreme caution when servicing this equipment.
Circuit boards, test points, and output voltages also may be floating above
(below) chassis ground.
WARNING
The equipment used contains ESD sensitive ports. When installing
equipment, follow ESD Safety Procedures. Electrostatic discharges might
cause damage to the equipment.
Important Safety Instructions
Before applying power to the system, verify that your product is configured properly for your
particular application.
Only qualified personnel who deal with attendant hazards in power supplies, are allowed to perform

1. Introduction
This instruction manual contains information on the installation, operation, calibration and
maintenance of all power systems that use the 3001i, 5001i, 3001iX, and 5001iX power sources
with the programmable controller. Higher power configurations consisting of multiple units
operated in parallel are also covered by this user manual. Such models are 10001iX, 10002iX,
15003iX and 30003iX.
1.1 General Description
The 3001i, 5001i, 3001iX, and 5001iX are high efficiency, lightweight AC power sources that
provide a precise output with low distortion. Older generation i Series have two voltage ranges,
either 0-135V or 0-270V. The iX Series and the newer generation i Series offer two sets of
ranges, 0-135/0-270 and 0-150/0-300. Full power is available at the maximum output voltage for
all ranges. Two or three 5001i/iX units can be connected in parallel as a single-phase system for
10 kVA or 15 kVA respectively. Three or six units can be connected as a three-phase system.
They can be operated with AC or DC output. The iX Series also offers AC+DC output mode.

3.1 Unpacking
Inspect the unit for any possible shipping damage immediately upon receipt. If damage is
evident, notify the carrier. DO NOT return an instrument to the factory without prior approval. Do
not destroy the packing container until the unit has been inspected for damage in shipment.
WARNING: This power source weighs 61 lb (28kg). Obtain adequate help when
moving or mounting the unit.
3.2 Power Requirements
The 3001i/iX AC Power Source has been designed to operate from a single-phase 208 to 240
volt AC line. The 5001i/iX AC Power Source and its systems have been designed to operate
from a three-phase AC line voltage. Three three-phase input models are available for inputs of
208-240 VLL, 400-440 V
(option -400), or 400-480 V
LL
(option -400).

CAUTION: Do not connect 400-480V into the 208-240V unit, the result could be a
severely damaged unit.
i Series / iX Series 15
User Manual
3.3 Mechanical Installation
The 3001i/iX and 5001i/iX are completely self contained power sources. They may be used free
standing on a bench top or rack mounted using the optional rack mount/handle kit. The units are
fan cooled, drawing air in from the sides and exhausting at the rear. The sides of each unit must
be kept clear of obstruction and a 6” clearance must be maintained to the rear. Special
consideration of overall air flow characteristics and the resultant internal heat rise must be
allowed for with systems installed inside enclosed cabinets to avoid self heating and over
temperature problems.
3.4 Input Wiring – TB1
The input terminal block, TB1, is located at the rear of the unit. Ground (earth) wire must be
connected to the chassis of the AC power system. The mains source must have a current rating
equal to or greater than the input circuit breaker and the input wiring must be sized to satisfy the
applicable electrical codes. The input terminal block cover and strain relief must be installed in
table top applications to maintain protection against hazardous voltages.
CAUTION: Capacitors in the power source may hold a hazardous electrical charge
even if the power source has been disconnected from the mains supply. Allow
capacitors to discharge to a safe voltage before touching exposed pins of mains
supply connectors.
3.5 Output Power Connections – TB2
The output terminal block, TB2, is located at the rear of the unit. The external sense inputs allow
the power system output voltages to be monitored directly at the load and must be connected
either at TB2 or the load when the sense is programmed for external. The external sense input
does not have to be connected when Internal Sense is programmed. The external sense wires
are to be connected to TB3 on the rear panel and should be run as a twisted pair for short
lengths. Sense leads over three (3) feet long should be run as a twisted shielded pair. Refer to
Figures 3-2 through 3-12 for all connections.
Note: The output of the power source is isolated from the input line and floating from
chassis ground. If needed, either side (HI or LO) may be grounded.

A number of connectors are located along the top rear covers. These connectors are in a
recessed area to protect them from shipment damage.
3.6.1 System Interface, Clock and Lock Connectors
WARNING: The system interface connector and Clock and Lock connectors may be at
hazardous voltages. These connections may not be used in table top applications. In
table top applications the safety cover must be in place. These connections may only
be used when the equipment is enclosed in a rack, only within one rack, only with
California Instruments supplied cables, and only between California Instruments
equipment.
J21 and J20 are the Clock and Lock connectors and are used to synchronize and control the
phase shift between the three outputs when 3 units are operating as a three-phase system with
the 15003iX - LK option.
The System Interface connector, J22, is used to connect the slave power sources to the Master
power source (the one with the controller) in multiple box systems. The connector is also used
for the external sync input, external modulation input and trigger output.

3.6.2 Remote Sense Connector TB3
When selecting external sense mode, it is important that the remote sense connections are
hooked up at the EUT or at the sense point. For single-phase systems, connect Phase A to
phase A and neutral to neutral. For three-phase system configurations, connect all three phase.
NOTE: Do not reverse or swap sense connection phasing or damage to the unit may
result.
All 3001iX and 5001iX AC Sources are shipped with the sense connections wired to the output
terminals. This will prevent a voltage fault when the external sense mode is selected. On
systems consisting of multiple 3001iX or 5001iX chassis, the end user has to connect the
external sense inputs to allow the system to operate. Some system configuration do not support
Internal sense mode in which case the sense connection must always be present at TB3.

3.6.5 Function Strobe / Trigger Out – J22-31 / J22-14
A function strobe output is available on the System Interface connector. This open collector output
may be used to trigger external equipment when voltage or frequency change occurs on the AC
source.
This output generates a low-going pulse, > 400 s in duration, that indicates voltage or frequency
change. Since this is an isolated output, an external DC supply and pull-up resistor, 22K , 1/8 W is
required. To create a TTL level output, a +5V or +3.3V DC supply is required. To create a signal for
viewing on a scope, a higher DC voltage such as a 9V battery may be used.
Connect the DC supply and pull-up resistor as shown.

3.7 Single-Phase and Three Phase Multiple Box System Configurations
Three Phase System:
The three phase system will be configured ready for use when ordered as such from the factory.
One unit, with the controller, will be identified as Phase A on the serial number tag. The other
two units will be identified on their serial number tags as either Phase B or Phase C. The power
sources must be installed in the system according to the phase markings on the serial number
tags. There will be one master unit that will have a full controller and the slaves will have blank
front panels except for the circuit breaker and indicator lights.
The three units must be interconnected using the system Interface cable. The three LO outputs
must also be connected together before applying power.
If the units were purchased as single phase units and have not been configured for a three phase
system please consult the factory.
Single Phase System:
In a single phase system consisting of two or three units there will be one master unit that will
have a full controller and the slaves will have blank front panels except for the circuit breaker and
indicator lights.
The units must all be connected with the system interface cable, but not the clock and lock
cables. The HI outputs on all the terminal blocks should be connected together. The LO
outputs should all be connected together and a heavy duty cable run to the load from the HI and
LO outputs. See Table 3-1 for cable sizing.
The appropriate jumpers have been installed at the factory before shipment. If it becomes
necessary to change the system to three phase output, please consult the factory.
3.8 Output Voltage Ranges
The iX Series power sources have four voltage ranges: 0 to 135, 150, 270 or 300 volts. These
ranges are organized in two pairs: 135/270 and 150/300. When operating on the 135 volt AC
range, the current limit can be programmed to a maximum value of 37 amps for the 5001iX or
22.2 amps for the 3001iX.
The standard power source defaults to the 150/300 range pair. To change voltage range pairs
perform the folowing steps:
1. Press the MENU key 2 times.
2. The cursor should point to UTILITY. Press the ENTER key to display the UTILITY 1 screen.
In the UTILITY 1 screen select VOLT/CURR control by moving the cursor by pressing the
key.
3. Press ENTER.
4. In the VOLT/CURR control screen select VOLT PAIR = . Press the key to change the
range pair to 135/270. Pressing the key again will program the 150/300 range pair.

3.9 Functional Test
CAUTION: Work carefully when performing these tests, hazardous voltages
are present on the input and output during this test.
Refer to Figure 3-8 for the test set up.
1. Connect an oscilloscope, voltmeter and/or distortion analyzer to the AC source output at the
output terminal block (TB2).
2. With the AC mains verified as being off, apply the correct three phase AC power input
voltage connections to the AC source input terminals barrier (TB1). Apply the AC mains
power and turn on the main circuit breaker on the AC source front panel.
3. Verify the front panel LCD display lights up with the initial start up screen showing the unit ID
and serial number. A self check routine screen with follow and finally the system will display
the main “Menu 1” screen with the cursor highlighting the “Program” selection.
4. Press “ENTER” and the unit will display the Program selection screen. Set the following
output parameters: output voltage = 150 volts, frequency = 60 Hz, voltage range = 150 volts,
and current limit = 20.0 amps (3001iX) or 33.3 amps (5001iX). Press “ENTER”.
5. Enable the output by pressing the output “on/off” button below the front panel display screen.
The green LED next to the button will light green when the output is on. The output should
be a clean 150 volt AC sinewave having less than 1% distortion.
6. Apply full load to the output of the source and verify the output remains within 2% of the initial
150 volt value. The output should still be clean and the distortion should still be less than 1%
at 60 Hz.
7. Using the PROGRAM screen set the output current limit value to 17 amps. The system
should go into current limit. Return the current value to 20.0 amps (3001iX) or 33.3 amps
(5001iX) and press the output on/off button to turn the output off. Disconnect the load.
8. Repeat steps 4 through 7 but set the output for the following: output voltage = 300 volts,
output range = 300 volts, current limit = 10.0 amps (3001iX) or 16.7 amps (5001iX). For step
7, the current limit value can be set to 8 amps.
In the unlikely event the power source does not pass the functional test, refer to the
calibration procedure in Section 6 or call California Instrument‟s customer satisfaction
department for further assistance.

4. Front Panel Operation
4.1 Tour of the Front Panel
The i and iX Series front panels are identical although some of the keys found on the front panel
are only used by iX Series models. If your unit is an i Series, these keys will act as don‟t cares.
This chapter provides information on operating the i and iX Series AC sources from the front
panel keyboard.
Before operating the AC source using the front panel, it helps to understand the operation of the
front panel controls. Specifically, the operation of the knob, keyboard and the menu layout are
covered in the next few paragraphs.
4.1.1 Front Panel Controls and Indicators
The front panel can be divided in a small number of functional areas:
Mains circuit breaker
Status Indicator lights
Shuttle knob
LCD display
FUNCTION keypad
DATA ENTRY keypad
4.1.2 Mains Circuit Breaker
The circuit breaker located on the bottom left side of the front panel disconnects the AC source
from the three phase Line input. It will automatically trip when the input current rating of the unit is
exceeded due to some component failure. The contrasting black color and large size throw bar
make it easy to locate in case of an emergency.
4.1.3 Status Indicator Lights
Four LED status indicators are located directly above the mains circuit breaker. These LED‟s
correspond to the following conditions:
REMOTE The REMOTE LED indicates that the unit is in remote control
mode. If the IEEE-488 interface is used, this indicator will be lit
whenever the REM line (REMOTE ENABLE) line is asserted by
the IEEE controller. If the RS232C interface is used, the
REMOTE state can be enabled by the controller using the
SYST:REM command. Any time the REMOTE LED is lit, the
front panel of the i Series unit is disabled. There is no LOCAL
button that allows the user to regain control of the front panel.
This prevents accidental change of settings in ATE applications.
OVERLOAD The OVERLOAD LED indicates an output overload condition.
i Series / iX Series 37
This condition can be controlled by setting the current limit value
in the PROGRAM menu. Removing the load using the OUTPUT
ON/OFF button will recover from an overload condition.

has been selected.
4.1.4 The Shuttle Knob
The shuttle knob is located to the right of the LCD screen and is used to change setup
parameters. Note that it cannot be used to move the cursor position between menu fields. Use
the UP and DOWN arrow keys in the FUNCTION keypad for this.
The shuttle knob can operate in one of two distinct modes of operation:

4.2.4 PROGRAM Menu
Figure 4-8: PROGRAM Menu
The PROGRAM menu is shown in Figure 4-8. It can be reached in one of two ways:
1. by selecting the PROGRAM entry in the MENU screen and pressing the ENTER key
2. by pressing the PROG key in the FUNCTION keypad
The PROGRAM menu is used to change output parameters. The most commonly used
parameters are all located in PROGRAM 1. The PREVIOUS SCREEN entry, when selected, will
return the user to the most recently selected menu. This is normally the MENU screen unless the
PROGRAM menu was selected using the PROG key on the FUNCTION keypad. Less frequently
used parameters are located in PROGRAM 2 which can be reached from the PROGRAM 1
screen using the MORE selection, or by pressing the PROGRAM key twice.
The following choices are available in the PROGRAM menus:
Entry Description
PROGRAM 1
VOLTAGE Programs the output voltage in rms. when in AC mode or
absolute voltage when in DC mode. In DC mode, negative
values can be entered.
FREQ Programs the output frequency when in AC mode. If the unit is
in DC mode, the value for FREQ will be set to DC and cannot be
changed until AC mode is selected. When in AC mode, the
frequency can be changed from 16 Hz to 500 Hz. Values
entered that fall outside this range will generate a -200 RANGE
ERROR and will not be accepted.
VOLT RANGE Selects 135/150V or 270/300V voltage range. The actual range
values may be different depending on the configuration. The
value of this field can only be changed with the shuttle or the +/key.
Note that the voltage range is coupled with the output relay
state on all i/iX AC sources with firmware revision 2.39 or
higher. If the output relay is closed (OUTPUT ON), the voltage
range cannot be changed.
CURR LIMIT Sets the current limit value for the current detection system.
When the load current value exceeds the set current limit, a
fault condition is generated. The actual response of the AC
Source to a current limit fault is determined by the protection
mode selected in the CONFIGURATION menu. (CC = Constant
Current, CV = Constant Voltage).
46 i Series / iX Series
User Manual
PHASE Selects the phase angle between the external clock and the
output of the AC source. If the clock source is internal, this
parameter has no effect.
CLOCK MODE Selects internal or external clock source. The i/iX Series uses
an open air crystal timebase with an accuracy of 100 ppm. To
improve output frequency stability and accuracy, an external
clock generator may be used.
VOLT MODE The iX Series offers three output modes, AC, DC and AC+DC.
The VOLT MODE field can be used to toggle between these
three output modes. Both the Knob and the +/- key may be used
to toggle through these three selections. In DC mode, no
frequency selection is possible and all maximum current and
power ratings are divided by two. The i Series offers AC or DC
modes.
DC OFFSET When the AC+DC mode is selected, the VOLTAGE field in the
PROGRAM 1 screen is used to set the AC portion of the output
voltage. The DC OFFSET field in the PROGRAM 2 screen can
be used to set the DC offset level. Either the knob or the
decimal keypad may be used to set the DC offset level.
PROGRAM 2
STARTø Selects the start phase angle for output changes made to either
voltage or frequency. This allows changing the output at a
specific phase angle. The output on key also uses this phase
angle setting to program the output voltage up to the set level
after the output relay is closed. The default value for this field is
RANDOM.
i Series / iX Series 47
User Manual
4.2.5 MEASUREMENTS Screens
The i/iX Series uses a DSP based data acquisition system to provide extensive information
regarding the output of the Source. This data acquisition system digitizes the voltage and current
waveforms and calculates several parameters from this digitized data. The result of these
calcalutions is displayed in a series of measurement data screens. The actual digitized
waveforms can also be displayed by selecting the Harmonics/Trace Analysis screen. A total of
four measurement screens are used to display all this information (iX series only).
Figure 4-9: MEASUREMENTS Screen, single phase and three phase modes
The first three Measurement screens available on the iX Series are not menus in that no
changes can be made anywhere. Instead, these three screens provide load parameter readouts.
The fourth measurement screen provides access to the advanced measurements and does offer
several user accessible fields (iX Series only). The measurement screens can be reached by
successively pressing the MEAS key which will toggle to all four available screens.
In three phase configuration iX Series, measurements are available for each phase individually.
To select the desired phase, use the PHASE key to toggle through phase A,B,C, or ABC. The
ABC mode displays the data for all three phases simultaneously.
The following parameters are available in the first three measurement screens:
Entry Description
MEASUREMENT 1
VOLTAGE When in AC or AC+DC mode, this value is the true rms output
voltage measured at the voltage sense lines. In DC only mode,
the voltage is the DC voltage including polarity.
CURRENT When in AC or AC+DC mode, this value is the true rms output
current drawn by the load. In DC only mode, the current is the
DC current including polarity
FREQ When in AC or AC+DC mode, the output frequency is measured
at the sense lines. When in DC only mode, this value always
reads “DC”.
POWER In both AC and DC mode, this value is the real rms. power
consumed by the load.
MEASUREMENT 2
VA POWER In AC or AC+DC mode, this value is the apparent rms. power
consumed by the load. In DC mode, this value is always the
same as the POWER readout.
48 i Series / iX Series
User Manual
PEAK CURR This readout reflects the peak current value detected at the
output. To measure inrush current for a unit under test, open the
output relay and reset the peak current value using the PEAK
CURR RESET entry. Then program the output voltage and
frequency and turn on the output relay. The peak current
measurement will continuously track the maximum current value
detected until reset.
POWER FACTOR This readout shows the power factor of the load.
CREST FACTOR This readout displays the ratio between peak current and rms
current.
VOLT THD This readout displays the total voltage distortion for the selected
phase.
CURR THD This readout displays the total current distortion for the selected
phase.
INST PK CURR This readout reflects the instantaneous peak current value
detected at the output. This value is updated continuously and
does not require a reset operation like the PEAK CURR readout.
The instantaneous peak current does not use a track and hold
mechanism like the PEAK CURR measurement in the
MEASUREMENT 2 screen. Instead, it tracks the peak current
on a cycle by cycle basis. The INST PK CURR typically tracks
the rms current and the crest factor.
MEASUREMENT 3 [iX Series only]
Update Program Functions from Measurement Screen
The Shuttle can be used to update program parameters such as voltage, frequency or current
from the measurement screen. This can be achieved with the following sequence:
1. Select the program 1 screen using the PROG key.
2. Use the up and down key to select the desired function to update. (Selects parameter that
will be changed by the shuttle once in the MEAS1 screen)
3. Select the measurement 1 screen by pressing the MEAS key.
4. The pointer symbol ( ) points to the programmed parameter (V,F or CL) that will be
affected by turning the shuttle.

HARMONICS/TRACE ANALYSIS Screen [iX Series only]
The fourth measurement screen is dedicated to the advanced measurements available on the iX
Series only. This screen is not available on the i Series. The Harmonics/Trace Analysis
measurement screen is a true menu screen offering several user accessible fields. These fields
are used to select the desired acquisition trigger and display mode. The actual data is displayed
whenever the ENTER key is pressed while the cursor is on the VIEW or START field. The
following fields are available on this menu:
Figure 4-10: HARMONICS/TRACE ANALYSIS screen
Entry Description
FUNCTION Selects Voltage, Current or Both parameters for display.
VIEW Available display modes are TABLE, BAR and TRACE.
50 i Series / iX Series
User Manual
DATA MODE Selects absolute or relative harmonics display for TABLE and
BAR view modes. In relative mode, all harmonics are shown in a
percentage of the fundamental which is normalized at 100 %. In
absolute mode, the harmonic amplitudes are shown in absolute
volts or amperes.
This mode does not apply to the TRACE view display mode and
is ignored when this mode is selected.
SCALE Sets the horizontal time axis for the TRACE view display mode.
The field can range from 4 ms to 104 ms in single phase mode
or 12 ms to 312 ms in three phase mode.
This parameter is ignored when the TABLE or BAR view display
mode is selected.
TRIG MODE This field sets the trigger mode for the acquisition. Available
options are SINGLE (single shot acquisition) or CONT
(continuous acquisition). In SINGLE shot mode, the acquisition
is triggered once each time the START field is selected and the
ENTER key is pressed. The selected trigger source is used to
determine the trigger point. Once the acquisition has been
triggered, the data are displayed and do not change until the
next acquisition is triggered. This mode is most appropriate for
single shot events such as start up currents.
In the CONT mode, acquisitions occur repeatedly and the data
is updated on screen after each trigger occurs. This provides a
continuous update of the data and is most appropriate for
repetitive signals.
TRIG SOURCE The trigger source selects the event that will trigger a
measurement acquisition. Available options for this field are
IMM (immediate), PHASE A or SET VOLT. The IMM trigger
source causes the acquisition to trigger immediately when the
ENTER key is pressed on the START field. Essentially, this is
an asynchronous trigger event. The acquisition will always be
triggered in this mode and data is available immediately.
The PHASE A source will cause the acquisition to trigger on the
occurrence of a set phase angle for the voltage on phase A. The
trigger source is always phase A when in this mode, regardless
of the phase selection shown in the top right corner of the
display. When the acquisition is started, the acquisition system
waits for the specified phase angle to occur before triggering the
acquisition. This mode allows exact positioning of the acquisition
data window with respect to the voltage waveform.
The SET VOLT mode causes the acquisition to trigger at the
specified voltage. This mode also programs the selected phase
or all three phases when the measurement is started from the
START field. As such, this trigger source selection also
programs the output voltage to the selected rms level.
TRIG PHASE / SET VOLT This field changes purpose, depending on the trigger source
i Series / iX Series 51
selected immediately above it. If the trigger source equals IMM
or PHASE A, this field can be used to program the trigger phase
angle (TRIG PHASE). In IMM mode, the value of this field is
ignored.
User Manual
If the trigger source is set to SET VOLT, this field can be used
to specify the rms voltage to program the output to and trigger
the measurement on. The voltage value set here should not
exceed the maximum voltage range selected or the rms
capability for the waveshape selected on the phase or phases
programmed.
TRIG DELAY The trigger delay field allows the trigger point to be positioned
anywhere in the acquisition window. A negative value will
provide pre-trigger information on data leading up to the trigger
event. The pre-trigger delay can not exceed the length of the
acquisition buffer (104 ms in single phase mode, 312 ms in
three phase mode). A positive trigger delay positions the data
window after the trigger event. Positive trigger delays can
exceed the length of the acquisition buffer in which case the
trigger event itself will not be in the buffer any more. The
maximum value of the trigger delay is 1000 ms. The default
trigger delay value is 0.0 ms which puts the trigger event at the
beginning of the acquisition window.
START The START field is used to start a new acquisition run. To start
an acquisition, place the cursor on the START field and press
the ENTER key. Once the ENTER key is pressed, the display
toggles to the data display mode selected in the VIEW field as
soon as the selected trigger event occurs. To return to the
HARMONICS/TRACE ANALYSIS menu, press the ENTER key
while in the data display mode.
To change display modes without triggering a new acquisition,
make the desired changes in the menu and move the cursor to
the VIEW field. Once on the VIEW field, press the ENTER key.
This will not trigger a new acquisition which means the original
data is retained.

4.2.6 TRANSIENTS Menu
Figure 4-11: TRANSIENTS menu
The transient menu provides access to the transient list data. Both the i and the iX Series have a
transient list of up to 32 data points. This is represented by 32 transient step numbers from 1
through 32. From the Transient menu, the desired transient step type can be selected. Based on
the user‟s choice, the relevant transient type sub menu will be shown. The START/EDIT
SEQUENCE sub menu allows the user to review and change any transient step or execute the
transient list. When executing a transient list, transient steps are executed in a ascending
numerical order. Steps that are not defined are skipped.
The following entries can be found in the TRANSIENTS menu:
Entry Description
VOLT SURGE/SAG Voltage surges and sags are temporary changes in amplitude.
The output voltage will change from its present value to a user
specified value for a specified duration. (Sag if the value is
lower, surge if the value is higher.) After this period has expired,
the output voltage returns to a user specified end value. This
value may or may not be the same as the value present prior to
the start of the sag or surge.
VOLT SWEEP/STEP Voltage sweeps cause the output voltage to change from the
present value to a user specified end value at a specified rate of
change. A voltage step on the other hand is an instantaneous
change in output voltage. The new value will be held for the
duration period specified by the user. The final output voltage
value of a sweep and a step transient step should be different
than the value at the start of the transient step or no change in
output value will occur.
FREQ SWEEP/STEP This transient type is similar to a voltage sweep/step except it
affects the frequency. Refer to the previous paragraph.
VOLT/FREQ SWEEP/STEP This transient type combines the previous two types into a single
step. The effect is that of changing the output voltage and
frequency simultaneously.
Note: While this transient is programmed as a single transient
step, two list entries are required to store this information. As
such, every VOLT/FREQ SWEEP/STEP used will consume two
list entries at a time.
START/VIEW SEQUENCE This entry allows the user to switch to the transient execution
menu. This menu provides a list of all available transient list
steps and their sequence numbers. From this menu, transient
list execution can be started.
The same menu can be used to view or edit any available
transient list step or erase a step using the backspace key.

screen as follows:
1. Scroll to the VOLT SURGE/SAG entry using the up and down cursor keys.
2. Press the ENTER key to bring up the VOLT SURGE/SAG screen.
The VOLT SURGE/SAG screen has several data fields. All data fields that are blank to the right
of the equal sign must be filled or an error message will occur when trying to leave this screen.
The EVENT # is the last data field to be filled. Entering the event data field will cause the display
to return to the TRANSIENT screen where a new selection can be made.
The VOLT/SURGE/SAG screen has the following fields:
START ø This field will show the start phase angle of the voltage transient
in degrees. Only one start phase angle per transient sequence
is allowed. The start phase angle must be in the first transient
event in the list. The start phase angle is not valid for DC
transients. If no start phase angle is required, this field can be
set to RANDOM by pressing the BACKSPACE (<-) key on the
decimal keypad.
GO TO VOLT This field will set the voltage level during the transient duration in
volts
DUR SCALE Duration scale default is time in seconds. Use the Shuttle knob
to select CYCLES if desired. Note that durations expressed in
cycles may cause rounding errors if the period of the selected
frequency setting is not an integer number of mss. Thus, for 50
Hz applications, no rounding errors occur but for 60 Hz, the
16.66¯ ms period will cause a rounding error when converted.
The Duration scale selection affects both the DURATION and
END DELAY parameters.
DURATION Duration is the time the output voltage level will dwell at the GO
TO VOLT level. The DUR SCALE defines the time scale of this
parameter in CYCLES or SECONDS
END VOLT This is the output voltage level at the end of the transient
EVENT and after a time specified by the DURATION
END DELAY This is the time delay the voltage level will stay at the END
VOLT level before it proceeds with the next transient event or
completes the transient.
FUNCTION [iX Series only] This field can be used to select the waveshape
to be used during this step of the transient sequence. Each step
can use a different waveshape from the available library of 50
user defined waveforms or the three standard waveforms. The
output waveshape changes upon entry into each step and
remains in effect for the duration of the step. The default
waveshape is always the SINE (sinewave).
54 i Series / iX Series
User Manual
REPEAT This is the number of times the SURGE/SAG transient event will
repeat before it will proceed to the next event or exit the
transient program. Note that the number of times the transient
event is generated is equal to the REPEAT + 1. Leave this value
at zero if only one execution of this event in the list is required.
EVENT # This must be the last item in the transient edit screen. All data
fields must be entered before inserting the EVENT #. The
EVENT # takes a value from 1 to 99. The EVENT # defines the
order of execution of the transient events in a multiple event
transient. It is a good practice to enter spaced EVENT #‟s to
allow insertion of an EVENT later if needed. (For example,
space them by 5.) Entry of a sequence EVENT # number will
cause the display to return to the TRANSIENT screen.

transient.
END VOLT This is the output voltage level at the end of the transient event
in volts.
DUR SCALE Duration scale default is time in seconds. Use the Shuttle knob
to select CYCLES if desired. Note that durations expressed in

frequency setting is not an integer number of mss. Thus, for 50
Hz applications, no rounding errors occur but for 60 Hz, the
16.66¯ ms period will cause a rounding error when converted.
The Duration scale selection affects both the DURATION and
END DELAY parameters.
DURATION Duration is the time it will take for the output voltage to reach the
END VOLT level. As such, “Duration” will define the slew rate of
the output voltage for the event. A duration of 0 seconds will
cause the output voltage to reach the end voltage immediately.
The DUR SCALE defines the time parameter CYCLES or
SECONDS
END DELAY This is the time delay the voltage level will stay at END VOLT
before it proceeds with the next transient event or completes the
transient.
FUNCTION [iX Series only] This field can be used to select the waveshape
56 i Series / iX Series
to be used during this step of the transient sequence. Each step

closed or an error message will appear and the transient will not
start.
Once a transient is in progress, this field changes to ABORT
and can be used to abort a transient in progress. If the transient
completes execution, the field reverts back to START.
PAUSE / RESUME The PAUSE field may be used to suspend execution of a
transient list in progress. If the cursor is on the PAUSE field and
the ENTER key is pressed, the transient is suspended and this
field changes to RESUME. Pressing the ENTER key again will
cause the transient list to resume execution from the point
where it was suspended.
REPEAT # This field determines the number of times a transient list is
repeated. The default value is zero which means the
programmed list runs only once. The range for this field is from
0 through 99999. This repeat function should not be confused
with the REPEAT function available for individual events. The
event specific repeat value will cause only that event to be
repeated, not the entire list.
CLEAR SEQ Moving the cursor to this field and pressing the ENTER key will
cause the entire programmed transient list to be erased. Be
careful not to press ENTER accidentally while on this field as
you will loose the programmed transient list. Note that a list may
be stored as part of the front panel setup in the nonvolatile
memory registers.

4.2.7 WAVEFORMS Menu [iX Series only]
Figure 4-17: WAVEFORMS menu
The WAVEFORMS menu is available on the iX Series only. If your unit is an i Series, pressing
the WAVE key on the front panel function keypad has no effect. The WAVEFORMS menu allows
selection of the waveshape for each phase individually or all phases at once. For three phase
versions of the iX Series, the mode is determined by the phase coupling. If only a single phase is
selected in the top right corner of the display (øA, øB or øC), the selected waveshape will be
applied to that phase. If all phases are selected (phase coupling), the selected waveform will
apply to all three phases.
For single phase versions of the iX Series, the phase coupling is always set to phase A, so
pressing the PHASE button has no effect.
The following fields are available in the WAVEFORMS menu:
CLIP LEVEL This parameter determines the amount of total harmonic
distortion of the built-in CLIPPED sinewave waveform. The
range is 0 % through 20 % THD.
Note that changing the distortion level of the CLIPPED sinewave
while the CLIPPED sinewave is used on the output of one or
more phases, forces the output of the AC Source to be dropped
momentarily. To avoid this, make sure none of the phases is
using the CLIPPED sinewave function when changing the clip
level.
GROUP The group field displays the currently selected waveform group.
The iX Series provides four groups of 50 user defined
waveforms each for a total of 200 waveforms. Only one group
can be active at a time however. This field only displays the
selected waveform group. It cannot be used to change the
actual group selected. Group selection must occur at power up
and is done from the INITIAL SETUP 3 screen. See section
4.2.11.3 for details.
MODE The mode field determines the operation mode of the
WAVEFORMS display screen. Available options for this field
are:
PROG: This mode is used to change the programmed
waveshape function on the selected phase. This is also the
default mode of operation.
VIEW(T): This mode can be used to display any of the
available user defined waveforms in a time domain display.
Previewing a waveform can be useful if you are unsure about
the nature of the waveform that was stored.
i Series / iX Series 61

VIEW(F): This mode can be used to display any of the
available user defined waveforms in a frequency domain
display. Waveform data is shown by harmonic amplitude and
phase relative to the fundamental frequency. Previewing a
waveform can be useful if you are unsure about the nature of
the waveform that was stored.
SINE The SINE is a standard waveform that is always available. It
does not consume any of the user defined waveform registers
and is always displayed in the waveform list. A right arrow
indicates the waveform is presently selected for the phase. If the
cursor is moved to this field, the ENTER key will execute the
selected MODE. If the mode is set to PROG, pressing ENTER
while the cursor is on the SINE entry will select the sinewave for
the phase shown in the top right corner of the display.
Note that the VIEW modes are not available for any of the three
standard waveforms.
SQUARE The SQUARE is a standard waveform that is always available. It
does not consume any of the user defined waveform registers
and is always displayed in the waveform list. A right arrow
indicates the waveform is presently selected for the phase. If the
cursor is moved to this field, the ENTER key will execute the
selected MODE. If the mode is set to PROG, pressing ENTER
while the cursor is on the SQUARE entry will select the square
wave for the phase shown in the top right corner of the display.
Note that the VIEW modes are not available for any of the three
standard waveforms.
CLIPPED The CLIPPED is a standard waveform that is always available. It
does not consume any of the user defined waveform registers
and is always displayed in the waveform list. A right arrow
indicates the waveform is presently selected for the phase. If the
cursor is moved to this field, the ENTER key will execute the
selected MODE. If the mode is set to PROG, pressing ENTER
while the cursor is on the CLIPPED entry will select the clipped
sinewave for the phase shown in the top right corner of the
display. The amount of clipping is determined by the CLIP
LEVEL field.
Note that the VIEW modes are not available for any of the three
standard waveforms.
USER DEFINED A list of user defined waveforms appears immediately below the
three standard waveforms. If no user defined waveforms were
downloaded to the iX Series AC source, this list will be blank.
User defined waveforms can be given a symbolic name of up to
twelve characters. The use of any of the three standard
waveform names (SINE, SQUARE and CLIPPED) should be
avoided as it will be rejected by the iX controller.

Entry Description
GPIB/RS232 SETUP This entry provides access to the setup parameters for either
the IEEE-488 bus or the RS232C bus. All parameters are saved
in non-volatile memory so their is rarely a need to change these
values.
UTILITY 1
VOLT/CURR CONTROL The voltage and current control menu can be used to select the
voltage range pair, the current limit method, the voltage sense
source, and the number of output phases (only in three phase
systems with Mode-iX option).
The standard available voltage range pairs are 135/270 and
150/300. The 135/270 pair gives higher current capability, and
the 150/300 gives higher voltage capability .
The two current limit choices are Constant Voltage and
Constant Current. Constant Voltage mode will maintain the set
voltage at the output until the load current exceeds the current
limit setting at which time the voltage will be dropped to zero.
This effectively shuts off the AC source output in case of an
overload condition. This mode has user programmable trip
delay which is located in the same menu.
Constant Current mode will maintain the load current at the
maximum level set by the current limit value, even if the
maximum power level is exceeded. This is done by reducing
the voltage as needed. As such, the voltage will be reduced
from the set level down to zero depending on the load
requirement. This mode is useful for starting up motor or
capacitor loads that may require a high inrush current. This
mode also has a user programmable trip delay.
Voltage sensing for regulation and measurement can be
selected for internal or external. External voltage sensing can
compensate for voltage drops caused by load cable impedance.
To achieve the best output regulation select external sense and
connect the voltage sense wires at the load.
The number of outputs in a multibox system with the Mode-iX
66 i Series / iX Series
option can be switched between one for 15000 VA single phase,
and three for 5000 VA per phase, three phase. If the Mode-iX
option is not installed, the number of outputs is fixed.
User Manual
INITIAL SETUP The initial setup menu can be used to determine the AC source
settings at power up. CAUTION: The initial setup can be used to
power up the AC source with the output on and a high voltage
present at the output. For normal situations, this is not
recommended due to the potential danger to operators. It is
recommended that the initial voltage be set low and/or the
output relay be programmed to OFF for most situations.
LIMIT SETUP The Limit menu shows the frequency, voltage and current limit
capabilities of the AC source. Any attempt to program the output
beyond these limits will result in a “-222 Data Out of Range
error”. Note that these limits are hardware determined and
cannot be changed by the user. They are shown for reference
only.
CONFIGURATION The Configuration menu shows the installed options. This
screen is for reference only and no fields can be changed by the
user.
ELAPSED TIME The elapsed time screen, when selected from the UTILITY
menu, will appear for about 3 seconds. The elapsed time shown
is the cumulative amount of time the power source has been on
from its initial build. This value is read only and cannot be
changed by the user.
UTILITY 2
The same screen also displays the internal AC source ambient
temperature in degrees C.
VIEWING ANGLE The viewing angle can be used to change the contrast ratio of
the LCD display. The range of the viewing angle parameter is
from -10 to +10. Setting the right viewing angle is matter of
personal taste. Set this parameter to a value that is most
comfortable for the user.

The GPIB/RS232 SETUP menu may be used to change the interface parameter settings for both
the IEEE-488 interface and the RS232 serial interface. The following parameters can be set from
this menu:
GPIB ADDRESS Sets the IEEE-488 address used by the AC source. The
address value can be set from 0 through 31. Address 0 is often
reserved for the IEEE-488 controller. The factory setting is
address 1. Once changed, the IEEE-488 address is retained in
nonvolatile memory.
RS232 BAUDRATE This field can be used to set the RS232 baudrate to either 9600,
19200 or 38400 baud. The baudrate set on the AC source must
match the one programmed for the communications port of the
controller.
RS232 DATA This field is used to set the number of databits to either 7 or 8.
Factory setting is 8 bits. This value must match the number of
data bits set on the communications port of the controller.
RS232 PARITY This field is used to set the parity. Available options are Even
(E), Odd (O) or no parity (N). Factory setting is No parity. This
value must match the parity set on the communications port of
the controller.
RS232 STPBITS This field is used to set the number of stop bits used on the
serial port. Available options are 1 or 2 bits. Factory setting is 1
stop bit. This value must match the parity set on the
communications port of the controller.
The number of start bits is always fiXed to 1 bit.

4.2.11.2 VOLTAGE/CURRENT CONTROL SETUP menu
Figure 4-22: VOLTAGE/CURRENT CONTROL SETUP menu
The VOLTAGE/CURRENT CONTROL SETUP menu may be used to set output voltage and
current control parameters. These parameters are not frequently changed in the normal
operation of the AC source and are thus located on the UTILITY rather than the PROGRAM
menu.
The following options are available in this menu:
VOLT PAIR [iX Series only] The iX Series can be operated in either a
135/270 voltage range pair or a 150/300 voltage range pair. The
amount of current available in the 135/270 range pair setting is
about 10% higher. Unless the extra voltage range is needed, the
maximum current can be attained in the 135/270 volt mode.
This field allows the selection of the most optimal voltage and
current combination for the application at hand.
OL MODE This field is used to select constant current (CC) or constant
voltage (CV) mode. The constant current mode will limit the
maximum amount of current drawn by the load to the set value.
The voltage will be reduced as needed after the trip delay time
to maintain the level of programmed current.
The constant voltage mode will maintain the set voltage as long
as the current drawn by the load does not exceed the current
limit programmed. If the current limit is exceeded, the output will
be shut off after the trip delay time.
TRIP DELAY The trip delay field may be used to set the amount of time to
hold off the current limit trip point. The minimum amount of time
is 100 ms or 0.1 sec. The maximum amount of time is 5.00 sec.
VOLT SENSE This field selects the internal or external sense line inputs.
Internal sense does not require the external sense lines to be
connected as sensing occurs at the output relay of the AC
source. For best results, connect the external sense lines and
select the EXT sense mode in this field. This will compensate
for voltage drop in the cables to the load. The measurements
are also taken at the sense points, so the external sense mode
should be used for best measurement results.
NO. OUTPUT This field is only accessible if the phase mode option is installed.
It allows the number of output phases to be toggled between
single and three phase mode. In single phase mode, all power is
available on phase A. The Mode-iX option is available to route
all power to a single output terminal pair.

4.4 Waveform Management [iX Series only]
The iX Series employs independent arbitrary waveform generators for each phase. This allows
the user to create custom waveforms. In addition, the iX offers three standard waveforms that
are always available. This chapter covers issues that relate to defining, downloading and
managing custom waveforms.
4.4.1 Standard Waveforms
For many AC applications, a sinewave shape is used. The sinewave is one of the standard
waveforms provided on the iX Series. The standard sinewave is always available and is the
default waveform at power-on. In addition to the sinewave, two more standard waveforms are
available, square and clipped.
Figure 4-28: Selecting a waveform
78 i Series / iX Series
User Manual
The square wave provides a high frequency content waveform with relative fast rise and fall
times. Due to AC amplifier bandwidth limitations, the frequency content of the standard square
wave has been kept within the amplifier‟s capabilities. As the fundamental frequency is
increased, the relative contribution of higher harmonics is reduced.
The clipped sinewave may be used to simulate voltage distortion levels to the unit under test.
The total harmonic distortion level may be programmed in percent using the CLIP LEVEL field of
the WAVEFORMS menu. Changing the distortion level of the CLIP waveform forces the AC
source to regenerate the CLIPPED sinewave‟s datapoints and reload the waveform register with
the newly requested data. This process requires the output to be dropped briefly. To avoid
interrupting the voltage output to the unit under test, select a different waveform such as the
standard sinewave first, change the clip level and change the waveform back to the CLIPPED
sinewave. This will avoid any output interruption.
4.4.2 Phase Selection
Figure 4-29: Selecting waveforms for single phase or all phases
If the 9003iX or15003iX, different waveforms may be selected for each phase. The number of
custom waveforms from which to select remains 50 but each phase can be assigned a different
custom or standard waveform. The specific output phase for which the waveshape is
programmed is selected with the PHASE key on the front panel. The selected phase is always
shown in the top right hand corner of the WAVEFORMS display.
To select the same wave shape for all three phases in a three phase configuration, press the
PHASE key until the øABC annunciator appears in the top right corner of the WAVEFORMS
menu. Waveform selections made in this mode will apply to all three phases.
4.4.3 Creating Custom Waveforms
The iX Series provides four groups of 50 custom defined waveforms each for a total of 200
waveforms in addition to the 3 standard waveforms. Of these four groups, one may be active at a
time. The active group is selected in the INITIAL SETUP menu.
Custom waveforms cannot be created from the front panel of the iX Series. Rather, they have to
be downloaded through the IEEE-488 or RS232C interface. A Windows based program is
included with the iX Series that allows waveforms to be created and downloaded easily. This
Graphical User Interface program allows waveforms to be created by specifying harmonic
amplitudes and phase angles with respect to the fundamental. It also offers an arbitrary
waveform data entry mode that allows individual data points to be specified.

Once downloaded, waveforms remain in non-volatile memory and will be visible in the
WAVEFORMS menu for selection. The user can assign a 12-character name to each custom
waveform. Avoid using any of the standard waveform names (SINE, SQUARE or CLIPPED) as
these names will not be accepted.
Waveforms may be deleted using the IEEE-488 or RS232C interface as well. Custom waveforms
cannot be deleted from the front panel however to avoid accidental erasure.
4.4.4 Waveform Groups
Waveform groups extend the number of available custom waveform to 200. Each group can
contain up to 50 user defined waveforms. Groups are numbered 0 through 3 and may be
selected from the INITIAL SETUP 3 menu. To switch waveform groups, proceed as follows:
1. Press the MENU key three times to select the MENU 3 screen.
2. Move the cursor to the UTILITY entry end press ENTER. You are now in the UTILITY 1
menu.
3. Move the cursor to the INITIAL SETUP field and press ENTER. You are now in the INITIAL
SETUP 1 menu.
4. Move the cursor to the MORE field at the end of this menu and press the ENTER key. You
are now in the INITIAL SETUP 2 menu.
5. Move the cursor to the MORE field at the end of this menu and press the ENTER key. You
are now in the INITIAL SETUP 3 menu.
6. Move the cursor to the WAVE GROUP = field. You can now use the knob or the 0 through 3
key on the front panel to select a different waveform group.
7. Press ENTER to confirm your new selection.
8. To activate your new selection, YOU MUST CYCLE THE POWER so the AC source re-
initializes. If the source is operated over the bus, a IEEE-488 Device Clear or reset command
(*RST) command will have the same effect.
The new wave group will be active after you turn the power to the unit back on.

4.4.5 RMS Amplitude Restrictions
The output of a sinewave may be programmed to the full rms value of the voltage range
selected. If the AC source is in the 300 V range, the maximum programmable rms voltage is 300
Volt. If a custom waveform is used however, the maximum programmable rms voltage may be
less than the maximum range value. The voltage range limit is based on the use of a sinewave
with a 1.414 crest factor. A 300 V rms sinewave has a 424 Volt peak voltage. The AC source has
a maximum peak voltage capability that is determined by the selected voltage range. If the user
selects a custom waveform with a crest factor that is higher than 1.414, the peak voltage would
exceed this maximum if the rms voltage were to be programmed at 300 V rms.
The iX Series automatically limits the maximum allowable programmed rms voltage of a any
custom waveform by calculating the crest factor of the selected waveform and controlling the rms
limit accordingly. Thus, each custom waveform may have a different maximum rms value. The iX
controller will prevent the user from programming the rms voltage above this limit. If a value is
entered in the PROGRAM 1 menu above this value, a “Voltage peak error” message is
generated.
Figure 4-31: Waveform crest factor affects max. rms voltage
The figure shown here illustrates the relationship between the crest factor of the waveshape (or
its “peakiness”) and the maximum peak voltage allowed for a given voltage range. Since the
peak voltage cannot exceed the AC source‟s capabilities, the programmable rms voltage has to
be restricted, in this case to only 167.8785 volt for the waveform on the left. The sinewave on the
right can be programmed to the full 300 V rms as this still falls within the same peak voltage
limitation of the AC source.
If the iX Series is used through the bus, the :VOLT? MAX query can be used to determine the
maximum allowable rms voltage for the selected waveform. Using the returned value as part of a
program will prevent range errors.
4.4.6 Frequency Response Restrictions
The user may create a waveform that contains any number of harmonic frequencies of the
fundamental. The AC Source itself however has a finite signal bandwidth and will attenuate
higher frequency components of the signal. To limit the maximum frequency component of the
output signal, the iX controller automatically applies a band-pass filter to all custom waveforms
as they are downloaded. This will limit the signal bandwidth to no more than 50 times the
fundamental frequency. Consequently, very fast transients embedded in the user provided
waveform data points may be modified as part of the download process. The frequency domain
VIEW mode in the WAVEFORMS menu may be used to visualize the content of each custom
waveform register on the LCD.

4.4.7 Switching Waveforms
Waveforms can be switched as part of the transient system. Each transient type setup menu has
a FUNCTION field. This field allows selection of any of the standard or custom waveforms
available in the selected group. Refer to the section on transients for more details on using
transient list to switch output waveforms.

4.5 Standard Measurements
Standard measurements are always available through the MEAS key on the front panel. These
measurements are spread across two to four screens to enhance readability. Switching between
these screens can be done by successively pressing the MEAS button on the front panel. This
will cause the screen to cycle through all available measurement screens.
4.5.1 i Series Measurements
For i Series units, the following two measurement screens are available:
4.5.2 iX Series Measurements
For iX Series, the following four measurement screens are available:
The iX Series has a fourth measurement screen for harmonics and trace analysis
measurements. This subject is covered in the next chapter.
Measurements are always running in the background. When the user selects a measurement
screen for display, the AC source first updates all the measurement parameters before
displaying the requested screen. This process may take up to a second. Consequently, pressing

the MEAS key may not always bring up the selected screen immediately. There will be a
perceptible delay. This will prevent the screen from appearing with invalid or blank readouts.
The measurement method for voltage and current will depend on the power source operating
mode. The following table shows the return value type (rms or average) and method of coupling
when the measurement command is initiated with a different extension at various operating
modes (AC, DC or AC + DC).
4.5.3 Accuracy Considerations
Any measurement system has a finite accuracy specification. Measurement specifications are
listed in Section 2. When using the AC source for measurement purposes, always consider these
specifications when interpreting results. Measurement inaccuracies become more pronounced
as the signal being measured is at the low end of the measurement range. This is particularly
relevant for low current measurements. The i and iX Series are high power AC sources
optimized for providing and measuring high load currents. When powering low power loads,
measurement inaccuracies on rms and peak current measurements will greatly affect derived
measurements such as power, power factor and crest factor.
The measurement system on the i and iX Series uses a data acquisition system with a 20 kHz
bandwidth. This means that high frequency components of the measured signal are filtered out.
Any contribution to the rms value of voltage and current above this cutoff frequency will not be
reflected in the i and iX Series measurements. When using an external measurement reference,
this may account for discrepancies in readings.

4.6 Advanced Measurements [iX Series only]
The iX Series offers advanced power analyzer measurement capabilities. These functions may
be accessed from the MEAS button or the MENU 2 screen. The phase for which the analysis or
waveform acquisition is done may be selected using the PHASE key in three phase
configurations. This chapter covers the use and application of these advanced measurement
functions.
4.6.1 Harmonic Analysis
The iX power analyzer performs fast fourrier transformation on both voltage and current on each
available phase. The resulting frequency spectrum can be displayed on the LCD display in a
tabular as well as a graphical mode.
4.6.1.1 Acquiring FFT data
To perform an FFT analysis on the output of the AC source, proceed as follows:
1. Press the MEAS button four times or until the HARMONICS/TRACE ANALYSIS screen
appears.
2. Move the cursor to the FUNCTION field and select VOLT or CURR. (The BOTH selection
will default to CURR as only one FFT result can be displayed at a time.)
3. Move the cursor to the VIEW field and select the TABLE or BAR display mode. The TRACE
display mode does not apply to FFT results.
4. Move the cursor to the DATA MODE field and select ABS or REL. Absolute display mode will
show all harmonic components in volts or amps. Relative display mode will use the
fundamental as a 100 % reference and display all harmonics as a percentage of the
fundamental. Phase angles are always shown with respect to the fundamental frequency.
The phase angle of the fundamental is always shown with respect to phase A.
5. Skip the SCALE field as it only applies to the TRACE display mode.
6. Move the cursor to the TRIG MODE and select SINGLE or CONT. The SINGLE mode will
acquire the data once and show the result. If you select CONT, the data will be updated
continuously.
7. Move the cursor to the TRIG SOURCE field and select IMM. We will cover additional trigger
modes later.
8. Move the cursor to the START field and press the ENTER key. The display that you selected
will be shown. If you are in CONT trigger mode, the data will be updated about once per
second.
You can return to the HARMONICS/TRACE ANALYSIS screen by pressing the ENTER key. To
display the data in a different format, change to the selections you want and move the cursor to
the VIEW field. Pressing the ENTER key will re-display the data without triggering a new
acquisition. (This is true even if you were in CONT trigger mode.) To start a new acquisition, you
must go through the START field instead.

4.6.1.2 Analyzing FFT data
The data displays available for FFT data allow you to scroll through the entire data set. For table
displays, the UP and DOWN arrow keys may be used to scroll through the table data vertically.
The knob has no function while in this display mode. The triangle on the left edge of the LCD
screen points to the current position in the table.
Figure 4-33: Scrolling through tabular FFT data
Bar chart format FFT data displays show the same data in a graphical format. While the
amplitude information is shown graphically, phase data is only displayed in numeric form to the
left for the currently selected harmonic component. The display can show up to 24 components
at a time. The triangle at the bottom of the display shows the currently selected component for
which numeric data is shown on the left. This data includes the harmonic number (DC through
50), the absolute or relative amplitude (depending on selected VIEW mode) and the phase angle
with respect to the fundamental. The knob can be used to scroll through the display horizontally.
The UP and DOWN cursor keys have no effect in this display mode.
