SAFETY SUMMARY

This power source contains high voltage and current circuits, which are potentially lethal. Because of its size and weight, mechanical stability must be ensured. The following safety guidelines must be followed when operating or servicing this equipment. These guidelines are not a substitute for vigilance and common sense. California Instruments assumes no liability for the customer’s failure to comply with these requirements. If the power source is used in a manner not specified by California Instruments, the protection provided by the equipment may be impaired.
BEFORE APPLYING POWER
1. Verify the correct three phase input voltage is applied to the unit. Input ratings are shown on the model and serial number tag located at the rear of the unit.
2. The chassis and cabinet of this power source must be grounded to minimize shock hazard. A chassis ground is provided at the input terminal block. This is located in the front of the cabinet on the lower left hand side. The lower front cover panel must be removed to access the line input and ground connections. The chassis ground must be connected to an electrical ground through an insulated wire of sufficient gauge.
FUSES Use only fuses of the specified current, voltage, and protection speed (slow blow, normal blow, fast blow) rating. Do not short out the fuse holder or use a repaired fuse.
DO NOT OPERATE IN A VOLATILE ATMOSPHERE Do not operate the power source in the presence of flammable gases or fumes.
DO NOT TOUCH ENERGIZED CIRCUITS Disconnect the power cable before servicing this equipment. Even with the power cable disconnected, high voltage can still exist on some circuits. Discharge these voltages before servicing. Only qualified service personnel may remove covers, replace components or make adjustments.
DO NOT SERVICE ALONE Do not remove covers, replace components, or make adjustments unless another person, who can administer first aid, is present.
DO NOT EXCEED INPUT RATINGS Do not exceed the rated input voltage or frequency. Additional hazards may be introduced because of component failure or improper operation.
DO NOT MODIFY INSTRUMENT OR SUBSTITUTE PARTS Do not modify this instrument or substitute any parts. Additional hazards may be introduced because of component failure or improper operation.
MOVING THE POWER SOURCE When moving the power source, observe the following:
1. Remove all AC power to unit.
2. Don not attempt to lift by hand. Raise the levelers and push the unit using two people to prevent injury or use forklift equipment with a qualified operator.
ALLOW CAPACITORS TO DISCHARGE
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 servicing internal circuits or touching exposed pins of mains supply connectors.

User Manual – Rev AJ California Instruments
1. Introduction
This instruction manual contains information on the installation, operation, calibration and maintenance of all power systems that use the MX Series power sources with the programmable controller.
1.1 General Description
The MX Series AC and DC power source systems are high efficiency, floor standing AC and DC power sources that provide a precise output with low distortion. Available voltage ranges are 150 Vac, 300 Vac and 400 Vac in AC mode and 200 Vdc and 400 Vdc in DC mode. The MX30­3Pi and MX45-3Pi can operate in either single or three-phase mode. The MX30 and MX45 is also available in just single or three-phase mode. All other models always operate in three­phase mode.
Models with a -1 or -3 designation provide full front panel operation but do not include certain features such as arbitrary waveform generation unless added as an option at the time of order. Models with the Pi controller offer several additional standard features, including the RS232C, USB, LAN (option) and IEEE-488 interfaces, arbitrary waveform generation, dual voltage ranges and additional measurement functions.
The MX Series units are contained in a compact floor standing enclosure on casters. This allows the units to be moved around more easily.
Read the installation instructions carefully before attempting to install and operate the MX Series power systems.
1.2 Manual organization and format
All user documentation for California Instruments power sources is provided on CDROM in electronic format. (Adobe Portable Document Format) The required Adobe PDF viewer is supplied on the same CDROM. This manual may be printed for personal use if a hardcopy is desired. To request a hardcopy from California Instruments, contact customer service at
[email protected]. There will be an additional charge for printed manuals.
This manual contains sections on installation, normal use, maintenance and calibration. If the MX system is equipped with a GPIB, RS232C, USB or LAN interface, refer to the MX Programming manual for information on using the remote control interfaces and command syntax. The programming manual is provided on the same CDROM as this user manual.

1.3 Different Model Series
There are two versions of the MX Series product, Series I and Series II. This user manual covers both MX model series with top level assembly part numbers 7003-400 (Series I) and 7003-422 (Series II). The difference between the Series I and the Series II is the controller used. The Series II uses a newer controller design but retains backward compatibility with the Series I products. The part number is shown on the model / serial number tag on the back of the MX series. All Series II will have a firmware revision of 4.0 or higher. The firmware revision is displayed briefly at power up on the LCD display and can also be queried over the bus by using the *IDN? command.
Differences between the two model series are restricted to:
 Reduced number of measurement calibration coefficients on Series II.
 Increased measurement sampling rate on Series II.
 Maximum DC offset range in AC+DC mode is 250Vdc on Series I, 220Vdc on Series II
Where relevant, differences are highlighted throughout the user manual.

3.3 Mechanical Installation
The MX's are completely self-contained power sources. They are to be used free standing on a solid surface. The units are fan cooled, drawing air in from the front and exhausting at the rear. The front and back of each unit must be kept clear of obstruction and a 6” clearance must be maintained to the rear. Special consideration of overall airflow characteristics and the resultant internal heat rise must be considered at all times to avoid self heating and over temperature problems.
3.4 AC Input Connections and Wiring
Three-phase Delta or Y AC input voltage of sufficient amperage (consult AC input specifications for maximum AC current per phase) is required to power the MX Series.
Note: AC power should be routed through a properly sized and rated three-phase
PROTECTIVE CIRCUIT BREAKER or similar branch circuit protection device with disconnect capability. This will protect building wiring and other circuits from possible damage or shutdown in case of a system problem. It will also facilitate removing AC input power to the MX system in case of service or reconfiguration requirements.
Note: AC input wiring and connections must conform to local electrical safety codes
that apply. Always consult a qualified electrician prior to installation of any MX System.
AC input connections are to be made directly to the input fuse block. The input fuse block is located on the lower left hand corner of the front of the MX chassis. To access the input fuse connection block, the protective front cover needs to be removed first.
CAUTION: Always disconnect any input power completely when removing
any protective cover and allow the internal capacitors to fully discharge (minimum of 15 mins) before removing any cover.) See Figure 3-2 for details.
No wiring for AC input connections is provided with the MX Series and must be provided by the end user or installer. Input wiring should be entered through the right hand side (when facing the back of the MX cabinet, see Figure 3-4) wire access opening located at the rear bottom of the MX chassis. A wire channel (marked as [2] in figure below) is provided below the input transformer to allow the input wiring to be routed to the front of the unit where the connections are to be made.
WARNING: The power source's input connection wiring gage (size)
must be sized for the maximum input current rating to ensure user safety and avoid possible power source damage, regardless of the actual output load.

Note: To comply with product safety requirements, EARTH GROUND must be
connected to the chassis of the AC power system using the ground stud located directly below the AC input fuse block. Use a Green/Yellow ground wire.
Note: DO NOT USE THE NEUTRAL CONNECTION OF A 3 PHASE Y AC POWER
CONNECTION IN PLACE OF A TRUE EARTH GROUND CONNECTION. AC power system neutrals cannot be used for protective earth ground.
The mains source must have a current rating equal to or greater than the input fuses and the input wiring must be sized to satisfy the applicable electrical codes. The front cover must be re­installed prior to use and the strain relief provisions located at the rear bottom of the unit must be used to maintain protection against hazardous conditions.

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. Power modules need at least 15 Minutes to discharge to safe levels before they can be removed.
3.5 AC On/Off Circuit Breaker on MX Series front panel.
It is important to understand the purpose and operation of the On/Off circuit breaker of the MX Series located on the lower left side of the front panel. This is a 2A rated breaker that is used to engage and protect the LV Power supply of the MX chassis only. The LV Power supply provides DC bias power to the entire MX system. The AC input power is routed through a set of three AC line fuses (F1, F2 and F3) located in the lower left bottom corner of the MX. (See Figure 3-2 for fuse locations). These fuses protect the three MX amplifiers and the AC input transformer from excessive input currents. The AC input power is connected to the input transformer through a large three-pole contactor. Removing AC power to the LV Power Supply by opening the front panel circuit breaker (moving the lever to the down (OFF) position) will cause this contactor to loose its coil voltage and will result in it opening and disconnecting the input transformer and amplifier from AC mains input.
Note: If any MX system failure has occurred on any part of the MX system, AC input
power must be removed immediately and
not restored until the system has been inspected by a qualifier service technician. Always turn off the On/Off Circuit breaker before re-applying AC input power.
40 MX Series

User Manual – Rev AJ California Instruments
CAUTION: The AC input fuses can only be checked is the MX unit is completely
de-energized and disconnected from any AC power input.
Note: Under no circumstances should AC input power be applied if one or more of the
AC input line fuses have failed and opened up.

If the model used is an MX30-1, MX30-3Pi, MX45-1 or MX45-3Pi with single-phase capability, the single phase A output connection is available on TB1B as well. Note that the neutral for either single or three-phase mode is always located on TB1B. The neutral connection is always required for single-phase output mode on an MX30-3Pi or MX45-3Pi and may be used if needed for the EUT for all three-phase output modes.
The external sense inputs allow the power system output voltages to be monitored directly at the load and must be connected at TB2 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 TB2 on the rear panel and should be run using a twisted shielded cable. See Figure 3-4 for location of TB2 and Figure 3-5 for shield connection detail.
Note: For External Sense connection, a shielded cable MUST be used with the shield
connected to chassis ground at the Ext. Sense connector. (See Figure 3-5).
External sense is recommended for multi-cabinet systems is the output wiring from the cabinets to the common output terminal block supplied is not of equal length.

Figure 3-11 shows the required output connections for a MX180-3Pi through MX270-3Pi three phase output configuration (rear-view perspective). For MX180, only 4 cabinets are used and for MX225 only 5 but otherwise the wiring diagrams are the same so only the complete MX270-3Pi configuration is shown.
Always disconnect all input power from the MX180, MX225 or MX270 before removing the front panel cover that provides access to the input and output terminal connections. Route the wires from the back of the MX45 chassis to the front in the provided cable guides.
For any of these system configurations, it is recommended to use the optional wiring junction box (P/N 7003-416-1). See section 3.13 for details. All output wires must be of equal length so it is advisable to place the master unit at or near the physical center of the set of units.

3.8 Multiple Cabinet System Configurations (incl. –MB)
Multi-cabinet MX models consist of two or three autonomous or Auxiliary MX45-3Pi units. Auxiliary units do not have their own controller and are identified easily by their blank front panel (except for status indicator LEDs). Master units each have their own controller but can be configured as auxiliary units by disconnecting the ribbon cable marked J17 between the controller and the system interface board (P/N 7003-700-1 or P/N 7003-715-1). This disables the controller and allows the MX45 to operate as an Auxiliary unit. (Requires removal of the top cover). See section 4.2.11.5 for information on setting the SYSTEM field in the configuration menu when changing configurations on MX systems with the –MB (Multi-box) option.
When used as a multi-cabinet system for higher power applications, the controllers in the unit(s) acting as the auxiliary to the master are either disabled or not present. For normal system configurations such as MX90-3Pi, the auxiliary unit will not have a controller or front panel and will have been factory configured for auxiliary operation.
For –MB systems such as MX90-3Pi-MB, the controller in the auxiliary unit must be disabled using S1. The SYSTEM field in the master unit controllers CONFIGURATION SETUP 3 screen must be set to the correct system configuration setting as well. The SYSTEM field for the controller in the auxiliary unit must be set to AUX if it is used as an auxiliary unit. See section
4.2.11.5.
Note: New SYSTEM field configuration settings do not take effect until power is cycled.
In addition to disabling the controller if present (as described above), the DIP switch (S1) located on the GPIB / RS232C / IO assembly in the auxiliary cabinets. (Requires removal of the top cover). The correct switch settings are shown below. (shown set for Master cabinet). Note that all units must be powered down before reconfiguring. Also, the output wiring must be changed to accommodate the

3.10 Clock and Lock Configurations
The MX Series may optionally be equipped for clock and lock mode of operation. This mode is a special form of Master/Auxiliary, which requires each chassis to have its controller. As such, i possible to create 2, 3, 6 or 9 phase power systems using 2 to 3 MX chassis. For most 2 or 3 phase configuratio recommended as it provides a single controller (and GPIB/RS232 control interface).
In a clock and lock configuration, each unit has its own front panel controls (as well as individual GPIB and RS232C interfaces) for operating the supply but the output frequency of the auxiliary unit(s) (-LKS option) is synchronized (locked) tot he Master MX unit (-LKM).
This mode of operation requires that one MX has the -LKM (Lock Master) option and one or two MX units have the -LKS (Lock auxiliary) option.

Remote Programming of Clock and Lock systems

Since clock and lock systems have multiple autonomous controllers that are synchronized in

3.11 Basic Initial Functional Test
CAUTION: Work carefully when performing these tests; hazardous voltages
are present on the input and output during this test.
Refer to Figure 3-19 for the required functional test set up. Proceed as follows to perform a basic function check of the power system:
1. Verify the correct AC line input rating on the nameplate of the MX unit(s) and make sure the correct three-phase line voltage is wired to the input of the MX before applying input power.
2. Connect a suitable resistive or other type load to the output of the MX. The load resistance value will depend on the voltage range you plan to check. Make sure the power resistor has sufficient power dissipation capability - up to 15 KW for full load test on one phase of MX45­3 or 10 KW for full load test on one phase of M30-3Pi - and that the load used does not exceed the maximum power rating of the MX. For three phase configurations, this test can be performed on one phase at a time if needed.
3. Connect an oscilloscope and DMM / voltmeter to the AC source output. Set both for AC mode.
4. If the correct voltage is present, turn on the MX unit(s) by closing the On/Off circuit breaker on the front panel. For multi-cabinet systems, turn on the auxiliary unit first and wait for them to cycle on, then turn on the master unit.
5. If the MX has more than one available output voltage range, go to the PROGRAM 1 screen and select the desired voltage range. The output mode can be set from the PROGRAM 2 screen (use the MORE soft key or press the PROGR function key again). Select AC mode.
6. Set the output voltage to 0 volt and close the output relay with the OUTPUT ON/OFF button. There should be little or no output although the DMM may show a noise level, especially if the DMM is in auto ranging mode.
7. Move the cursor to the VOLTAGE field in the PROGRAM 1 screen and either use the keyboard to program a small voltage (20 VAC) or slew the voltage up slowly with the knob. Observe the DMM reading. The reading should track the programmed voltage.
8. Also monitor the scope. The output should be a sinusoidal voltage waveform.
9. If the output tracks, increase the voltage till you reach 80 % of the voltage range or more. Check the output voltage reading and waveform.
10. Select the MEASUREMENT 1 screen by pressing the MEAS button. The output voltage, current and power will be displayed. For three phase configurations, use the PHASE button to select the øABC display mode. This will show the voltage, current and power for all three phases. If all phases ar t and power should be visib for all three unless the volta ame level. If only one phase is loaded, current and power will only be shown for the loaded phase.

3.12 Remote Inhibit / Remote Shutdown
It may be necessary to provide a remote shutdown of the AC or DC output of the MX. The external remote inhibit input may be used for this purpose (RI). This input is also referred to as remote shutdown.
The default mode of operation for the RI input is a contact closure between pins 5 and 6 (return of the rear panel screw-terminal strip. This will open the output relay of the MX.
If the firmware revision of the MX is 0.28 or higher, it is possible to reverse the polarity o input. This requires the use of the following bus command:
OUTPut:RI[:LEVel] HIGH /* Sets RI polarity to active high.
OUTPut:RI[:LEVel] LOW /* Sets RI polarity to active low (Factory default)
The remote control interface must be used to change this setting. Once set, the polarity setting remains available.
MX Series
When set to HIGH, an active low TTL level or a contact closure is required to enable the o relay of the MX. Opening the contact or removing the low input signal will cause the output rela to open.

3.13 Junction Box Accessory
An optional wiring junction box (P/N 7003-416-1) is available which may be used to connect the outputs of 2 to 6 MX cabinets together. The junction box also has a protective ground connection, which MUST be connected to a suitable protective earth ground.
Each junction box has four sets of terminals for phase A, phase B, phase C and Neutral. Each terminal is lined up with a strain relief on each side. The outputs from the MX45 cabinets connect to the “MX SYSTEM OUTPUT” side of these terminal blocks. The load can be connected to the “LOAD”. Note that the wiring is not supplied with the system and must be provided by the end user. The wire gauge of the load connection must be sized to handle the maximum current in the low voltage range of operation.
The “MX SYSTEM OUTPUT” side of the terminal block will accept up to 8 wires. If the external sense connection is made at the junction box, one of these can be used to connect the sense wiring.
Note: Do not swap output load wires or sense wires between phases, as damage to the system will result.
The “LOAD” side will accept 2 wires. The wire size range shown in Figure 3-20 refers to mechanical compatibility of terminal block only. This information does not reflect required wire size. The wire sizes accepted by the terminal blocks of the junction box on each side are shown in Figure 3-20.

The output of the MX30/45 is connected to the input side of the filter. Use terminal blocks TB1A (phases A and B) and TB1B (phase C and neutral) as indicated in Figure 3-21. The load can be connected to the load side of the filter box using terminal blocks TB2A and TB2B. Do not swap phases through the filter.
To compensate for voltage drop across the filter, the external sense connections can be made at the load (load side of the filter).
Note: The filter box chassis must be connected to earth ground.
It is not recommended to use the ground connection on the MX30//45 itself for this purpose but rather a ground point at the AC service to the MX30/45.

3.15 Fuse Box Accessory
An Output Fuse Box (P/N 7003-426-1) is provi cabinets. This fuse box prov amplifiers in different chassis in case of a system malfunction.
Each fuse is capable of sustaining up to 125 Arms of AC current, which is the maximum available current per MX amplifier.
Each fuse box has 9 sets of 3 fuses for phase A, phase B and phase C. Each fuse terminal is lined up with a strain relief on each side of the box. The outputs from the MX45 cabinets connect to the “MX 45 SOURCE” side of fuse box. The outputs of the fuse box (marked “JUNCTION BOX” are normally routed to the 7003-416-1 Junction box (marked “MX SYSTEM OUTPUT”) where the outputs of the various cabi connected to the “LOAD” side of the junction box.

Before operating the AC source front panel controls. Specifically, covered in the next few paragrap
4.1.1 Front Panel Controls and Indica
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 E
4.1.2 System On/Off Circuit Breaker
The circuit breaker located on the bottom left side of the front panel disconnects the low voltage supply of the MX Source from the three phase Line input. This will remove power from the mains AC input contactor and thus remove input power from the MX Series power source. As such, the circuit breaker acts as an indirect power on/off switch for the MX Series unit. Note however than AC input power remains applied to the primary side of the input transformer.

When the input current rating of the MX Series AC power source is exceeded, the protective fuses (F1 through F3) will blow. In this case, power to the low voltage supply may still remain through the front panel circuit breaker. In this case, the on/off circuit breaker should be opened (power off) first followed by a complete disconnect of all ac input power through an installed main circuit breaker.
Note that in MX60, MX90 and MX135 systems, each unit has its own on/off circuit breaker and set of line input fuses.

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 RS232, USB or LAN 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 MX 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.
This condition can be controlled by setting the current limit
value in the PROGRAM menu. Removing the load usin
g the OUTPUT ON/OFF button will recover from an overload condition.
OVER TEMPERATURE The OVER TEMPERATURE LED indicates an overheating
problem inside the unit. This is an abnor
mal condition, which will cause the unit to shut off. Check the air openings to make sure they are not blocked.
HI RANGE The HI RANGE LED is on when the high voltage output range
has been selected.

OUTPUT ON/OFF The OUTPUT ON/OFF key toggles the output relay on or off.
The state of the output relay is reflected by the green LED located directly to the left of the OUTPUT ON/OFF key. If the green LED is lit, the output relay is enabled (closed) and the programmed output voltage is present at the output terminal
s. If the green LED is off, the output relay is open and both the HIGH and LO terminal of the output term
inal block are disconnected from the power source. In this mode, the output is floating. The ON/OFF button provides a convenient way to disconnect the load without having to remove any wires.
PHASE The PHASE key is used to select the phase on a MX30-3Pi or
MX45-3Pi model. Pressing the PHASE key will toggle phase A, B, C or ABC. Some screens may not support the ABC or show all phase information in which case this mode is skipped. (3Pi controller only)
SET The SET key is used to select the mode of operation of the
shuttle. Refer to section 4.1.1 for details on its operation and the use of the SET key.
+/- The +/- key can be used to toggle the sign for those parameters
for which it is relevant. This is typically the output voltage when in DC mode of operation. For fields that have only two possible values such as the voltage range field, the +/- key can be used to toggle between these two values.

CD Display
The LCD display of the MX Series power source provides information on instrument settings and also guides the user through the various menus. To ease reading of the displayed information, most screens are widely spaced. A sample of the main menu 1 screen that appears when the MX Series source is powered up is shown in Figure 4-6. Due to the amount of space available on each screen, some menus have been split into parts. The MORE selection located at the bottom right hand side provides access to menu choices at the same level that did not fit on a single screen. Thus, to access MENU 2, the cursor should be placed on the ‘MORE’ selection followed by pressing the ‘ENTER’ key. Alternatively, the MENU key may be pressed to move to the MENU 2 screen.
The present cursor position is always shown with a inverse bar. The cursor is located on the ‘MORE’ selection in Figure 4-6. Pressing ENTER would cause MENU 2 to be displayed.
The cursor position can be moved by using the UP and DOWN keys located in the DECIMAL keypad.

PROGRAM 1
VOLTAGE Programs the output voltage in Vrms while 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 150V, 300V or optional 400V range in AC mode and
200V or 400V range in DC mode. 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.
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).
PROGRAM 2
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 MX Series
controller uses an open-air crystal time base with an accuracy of 100 ppm. To improve output frequency stability and accuracy, an external clock generator may be used.
VOLT MODE The MX Series offers three output modes, AC, DC and AC+DC.
The VOLT MODE field can be used to toggle between the

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 S
TART 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

Description
Voltage surges and sags are temporary changes in amplitude.
The output voltag
e 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 outp
ut 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 ste

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 sine wave waveform. The range is 0 % through 20 % THD.
Note that changing the distortion level of the CLIPPED sine wave while the CLIPPED sine wave 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 sine wave function when changing the clip level.
GROUP field displays the currently selected waveform group.
The group There are 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
