2. Safety Issues

Normal use of test equipment presents a certain amount of danger due to electrical shock because it
may be necessary for testing to be performed where voltage is exposed.

An electrical shock causing 10 milliamps of current to pass through the heart will stop most human
heartbeats. Voltage as low as 35 VDC or 35 V
hazardous, as it can produce a lethal current under certain conditions. Higher voltages pose an even
greater threat because such voltage can easily produce a lethal current. Your normal work habits
should include all accepted practices that will prevent contact with exposed high voltage and steer
current away from your heart in case of accidental contact with a high voltage. You will significantly
reduce the risk factor if you know and observe the following safety precautions:

 If possible, familiarize yourself with the equipment being tested and the location of

its high-voltage points. However, remember that high voltage may appear at unexpected
points in defective equipment.

 Do not expose high voltage needlessly. Remove housing and covers only when

necessary. Turn off equipment while making test connections in high- voltage circuits.
Discharge high-voltage capacitors after shutting down power.

 When testing AC powered equipment, remember that AC line voltage is usually

present on power input circuits, such as the on-off switch, fuses, power transformer, etc.

 Use an insulated floor material or a large, insulated floor mat to stand on, and an

insulated work surface on which to place equipment. Make certain such surfaces are not
damp or wet.

 Use the time-proven “one hand in the pocket” technique while handling an instrument

probe. Be particularly careful to avoid contact with metal objects that could provide a good
ground return path.

 Never work alone. Someone should always be nearby to render aid if

necessary. Training in CPR first aid is highly recommended.

AC should be considered dangerous and

menu.

 Blinking Light

Indicated the unit is actively generating pulses, or
armed and waiting for an external trigger.

 Question Mark

In external PLL oscillator operation mode, this
indicates the internal PLL is not yet locked with the
external clock source.

 “e”

An “e” will appear when the system clock is in external

mode, but not when in external with PLL.

 Menu Keypad

Provides one touch access to the channel, trigger,
gate, and system menus for setting up the appropriate
parameters. The Page button will allow you to page
through the multiple levels of a menu, if multiple levels
exist.

 Arrow Keypad

the current cursor parameter (indicated by the blinking
cursor). The position of the cursor controls the step
size for each increment. The right/left arrows move the
cursor to different positions within the current
parameter. The NEXT key selects the next parameter
in the currently displayed menu.

4. Pulse Concepts and Pulse Generator
Operations

Counter Architecture Overview

System Timer Functions

The System Timer functions as a non-retriggerable, multi-vibrator pulse generator. This means that
once started, depending on the mode, the timer will produce pulses continuously. Before pulses can
be generated, the timer must be armed and then receive a start pulse. Arming the counter is done by
pressing the Run/Stop key. With external trigger disabled, the Run/Stop key also generates the
start command for the counter. With external trigger enabled, the external trigger provides the start
pulse. In either case, once started, the counter operation is determined by the System Mode
Generator. Standard modes include:

The T0 pulse is distributed to all of the start inputs of the Channel Timers and Mode Generators.

9530/8530 Manual Version 4.8 Page 9

Channel Timer Functions

 Normal

A pulse is generated for each T0 pulse.

 Single Shot

One pulse is generated for the first T0 pulse, after

which the output is inhibited.

 Burst

‘N’ number of pulses are generated for the first T0

pulse, after which the output is inhibited.

 Duty Cycle

‘N’ number of pulses are generated for each T0 pulse

after which the output is inhibited for ‘M’ number of
pulses. The cycle is then repeated for each
subsequent T0 pulse.

The Channel Timer functions as a non-retriggerable, delayed, one shot pulse generator. This
means that the timer will only generate one delayed pulse for every start pulse received. Once the
channel timer has started counting, additional start pulses will be ignored until the pulse has been
completed (non-retriggerable). The start pulse for each channel is provided by the internal T0
pulse generated by the internal system timer. Whether or not a pulse is generated for each T0
pulse is determined by the Channel Mode Generator. Standard modes include:

Different modes may be selected for each output, allowing a wide variety of output combinations.
Each output may also be independently disabled or gated (using the external gate input).

Digital Output Multiplexer

The output s of each of the Channel Timers is routed to a set of multiplexers. This allows routing of
any or all Channel Timers to any or all of the units’ outputs. In the normal mode of operation, the
output of the nth Channel Timer is routed to the nth output connector. As an example, if a double pulse
is required on Channel A, one can multiplex the Channel A timer with the Channel B timer, then
adjust each timer to provide the necessary pulses.

Dependent & Independent Timing Events

The 9530 allows the user to control the relationship between the Channel Timers by setting the sync
source for each timer. Independent events are all timed relative to the internal T0 start pulse.

Dependent events may be linked together by setting the sync source to the controlling event. This
allows the instrument to match the timed events and adjustments can be made in one event
without detuning the timing between it and the dependent event.

Navigating the 9530 Front Panel

Selecting Menus

Parameters are grouped in menus, selectable by using the function keys. To select the output
channel parameters press the letter key corresponding to the desired channel. Menus may include a
number of different pages, each page containing up to four parameters. The status block in the
upper-left corner of the display shows a vertical arrow if the current menu contains additional pages.
Press the Page button to select the next page. There may be multiple channel menus depending on
the model. Secondary or advanced menus can be accessed by pressing the letter key of that channel

Page 10 9530/8530 Manual Version 4.8

a second time.

Wid:

Sets the width of the active portion of the pulse.

Dly:

Sets the delay from the sync source to the rising edge of the pulse.

There are also individual menu keys for the gate (GATE), trigger (TRIG), and system (MENU)
menus. Depending on the model, each of these menus may have multiple pages, accessed by
pressing the Page button, or secondary menus, accessed by pressing that particular function
key a second time.

Selecting Menu Items

Within a menu, the blinking cursor indicates the current menu item for editing. The NEXT key will
select a different menu item.

Numeric Input Mode

When the current item is numeric, the system enters the Numeric Input Mode. In this mode data may
be edited using the arrow keypad. The Left and Right arrow keys are used to select a digit to edit.
The selected digit blinks to identify itself as the active digit. The Up and Down arrow keys are then
used to increment or decrement this digit.

Entering Non-Numeric Parameters

When the current item is non-numeric, the Up and Down arrow keys are used to select among
different options for the parameter. If the item is an on-off toggle, the Up arrow enables the item and
the Down arrow disables the item.

Enabling System Output

The Run/Stop key is used to arm the system. With external trigger disabled, the key will arm and
start pulse output. With external trigger enabled, the key will arm the pulse generator. Pulse outputs
then starts after the first valid trigger input. Pressing the Run/Stop key a second time disables the
pulse generator.

Enable/Disable Channel Output

At the top of each channel menu page is a parameter to enable or disable the output of the
channel. Each channel may be individually enabled or disabled.

Rearming the Channel Timers

If there are channels currently running in normal mode, single shot and burst mode channels can be
re-armed without affecting the timing on normal mode channels. The rearming page is located under
the System Menu. Once on the rearming page, pressing the up arrow will rearm the channel timers.

Setting Pulse Timing Parameters

Pulses are defined by a delay, from their sync or start pulse to the active edge, and a width.

*NOTE: If Wid + Dly + 75 ns (the hardware reset time) > T0 period the correct pulse width will

be generated, but at a slower rate.

9530/8530 Manual Version 4.8 Page 11

Out:

Selects between TTL/CMOS mode and Adjustable
mode when both are available on a single output.

Pol:

Sets the voltage polarity of the pulse, active high or

active low.

*Note: All outputs are positive voltage as negative
voltages are not supported

Ampl:

In Adjustable mode the unloaded output voltage is set.
The actual output voltage will depend on the load

impedance. For example: If the load is 50Ω the output

will be 50% of the stated voltage.

Setting Pulse Output Parameters

There are two basic types of outputs available on the 9530:

a) TTL/CMOS compatible outputs.

b) Adjustable amplitude outputs.

Using the Output Multiplexer

Each output channel includes a multiplexer which allows routing of any or all of the timer outputs to
the physical output. This allows double pulses and other complex pulse trains to be generated.

The multiplexer is represented by an “n” bit binary number as shown above. “N” is the number of
channels. Each bit represents a channel timer, which is enabled by setting the bit to one. In the
above example, timers A and C are combined on the current output.

Setting System Internal Rate Parameters

The internal T0 period controls the fundamental output frequency of the system. Each channel may

be operated at submultiples of the fundamental frequency by using the channel duty cycle mode.

To set the system Internal Rate press the Menu key, then use the arrow keys

to specify the T0 period.

Quick Start - Normal Internal Rate Generator Operation

The 9530/8530 has a powerful set of functions providing a number of modes of operation for the
internal or “System” rate generator (T0). Most of these functions can be ignored if a simple

continuous stream of pluses is required. Starting from the default settings, which can be restored
by recalling configuration 0, the following parameters need to be set:

Quick Start – Normal External Trigger Operation

To generate a single pulse for every external trigger event, based on the default configuration 0,
the following parameters need to be set:

Page 26 9530/8530 Manual Version 4.8

System Timer Overview

For internal operation, the 9530/8530 contains a timer and mode generator which generates an
internal T0 clock that is used to trigger all the channel timers. System modes are controlled via the
Mode menu.

Using Continuous Mode

The Run/Stop button starts and stops a continuous pulse stream at the rate specified by the Rate
menu. This corresponds to the normal output mode for most pulse generators. To generate a
continuous stream of pulses:

 Within the System Mode menu select Continuous mode.
 Within the Rate menu:

o Select the system oscillator or external clock in frequency.
o Set the desired frequency

Pressing the Run/Stop key will now generate a stream of T0 pulses at a rate specified by the period
parameter.

Using Single Shot Mode

To generate a single pulse with every press of the Run/Stop key:

 Within the System Mode menu select Single Shot mode.

Pressing the Run/Stop key will now generate one pulse.

Using System Burst Mode Function

The Run/Stop button generates a stream of ‘N’ T0 pulses, where the ‘N’ is specified by the Burst

parameter. The rate is specified in the Rate menu. Pressing the Run/Stop button while in the burst
is in process will stop the output. After the burst has been completed, pressing the Run/Stop button
will generate another burst. To generate a burst of pulses set:

 Within the System Mode menu:

o Select mode to be Burst
o Set the Burst parameter to produce the number of pulses desired

Using the System Duty Cycle Function

The Run/Stop button starts a continuous stream of T0 pulses, which oscillates on for ‘N’ pulses and

off for ‘M’ pulses, where ‘N’ and ‘M’ are specified by the On/Off parameters respectively. The rate at

which the pulses are generated is controlled in the Rate menu. To generate a stream of pulses
which will oscillate on for ‘N’ pulses and off for ‘M’ pulses set:

 Within the System Mode menu:

o Set the mode to Duty Cycle.
o Set the On parameter to the number of pulses to produce during the on cycle (‘N’).
o Set the Off parameter to the number of pulses to suppress during the off cycle (‘M’).

 Within the Rate menu:

o Set the Source to either the systems internal oscillator or to external mode.

9530/8530 Manual Version 4.8 Page 27

o Set the desired frequency.

Channel Timer Overview

The output of each channel is controlled by two timers to generate the pulse width and the delay
timing. All channels are simultaneously triggered, depending on the system mode, by the internal T0

pulse, the external trigger, or a trigger provided by a CPU. A given channel may or may not
generate a pulse depending on its own channel mode as described below.

Using Channel Normal Function

The Normal mode generates a continuous string of pulses once the Run/Stop key is pressed. To
use channel normal mode set:

 Within the Channel menu:

o Enable the channel output
o Set the delay desired.
o Set the pulse width desired.
o Set the mode to Normal.

Pressing the Run/Stop button key will now generate a continuous stream of pulses.

Using Channel Single Shot Function

The Single Shot mode generates a single pulse every time the Run/Stop key is pressed. To use the
channels’ single shot mode set:

 Within the Channel menu:

o Enable the channel output.
o Set the delay desired.
o Set the pulse width desired.
o Set the mode to Single Shot.

Using the Channel Burst Mode

The burst mode generates a burst of pulses every time the Run/Stop key is pressed. To use the
channels’ burst mode set:

 Within the Channel menu:

o Enable the channel output.
o Set the delay desired.
o Set the pulse width desired.
o Set the mode to Burst.
o Set the Brst parameter to the number of pulses to produce during the on cycle (‘N’).

Using the Channel Duty Cycle Mode

The channel duty cycle mode will generate a stream of pulses on the channel level which will
oscillate on for ‘N’ pulses and off or ‘M’ pulses. To generate the stated sequence of pulses set:

 Within the Channel menu:

o Enable the channel output.
o Set the delay desired.

Page 28 9530/8530 Manual Version 4.8

o Set the pulse width desired.
o Set the mode to Duty Cycle.
o Set the On parameter to the number of pulses to produce during the on cycle (‘N’).
o Set the Off parameter to the number of pulses to suppress during the off cycle (‘M’).

*Note: Older Quantum Composer pulse generators had a divide-by-’N’ function. The duty cycle mode

is a more general case of this operation. To reproduce the divide-by-’N’ function set the on
cycle to 1 and set the off cycle to ‘N’-1, where ‘N’ is the divide by factor.

External Input Overview

The external inputs may be used to trigger the unit, gate the system timer, or to gate the channel
timers. When using the trigger input the external input acts s a system start pulse. Depending on the
system mode, the result of a trigger input can be a single pulse, a burst of pulses, or the start of a
stream of pulses.

Using the External Gate to Control the System

The external gate may be used to control the output of the unit. To gate the internal system timer
with an external source set:

 Within the Gate menu:

o Choose either Pulse or Channel Inhibit.
o Set the threshold level to ~50% of the incoming gate signal.
o Choose either active High or Low.

 Within the System Mode menu select the desired mode.

Pressing the Run/Stop button will arm the unit. Once the unit is armed it will start generating pulses
once the external gate is in the active state. Pressing the Run/Stop key again will disarm the unit.

Using the Channel Gating Function

Each channel may use the external input to gate or control its output. The gate controls the
triggering of the channel. To use the channel gate set the following parameters:

 Within the Gate menu:

o Set the mode to Chan Menu.

 Within the Advanced Channel menu:

o Set the channel gate parameter to either Pulse Inhibit or Output Inhibit.
o Set the gate logic to either Active High or Active Low.

In Pulse Inhibit mode the gate prevents the channel from being triggered by the channels’ trigger

source. When in Pulse Inhibit mode if a pulse has already started when the gate disables the
channel the pulse will continue normal output, but the output will not restart on the next trigger
pulse. In Output Inhibit mode the gate leaves the base triggering alone and will enable/disable the
output directly. When in Output Inhibit mode if a pulse has already started when the gate disables
the channel the pulse will be immediately cease.

Generate a Pulse on Every Trigger Input

To generate a pulse on every trigger input set the following parameters:

9530/8530 Manual Version 4.8 Page 29

 Within the System Mode menu set the mode to Single Shot mode.
 Within the Trigger menu:

o Select the Triggered mode.
o Set the trigger threshold level to ~50% of the incoming signal.
o Select either rising or falling edge for the unit to trigger on.

Pressing the Run/Stop key will arm the unit. Once the unit is armed it will generate a T0 pulse for

every external trigger received. Pressing the Run/Stop button again will disarm the unit. This mode
corresponds to the normal external trigger mode found on most other pulse generators.

Generate a Burst of Pulses on Every Trigger Input

To generate a burst of pulses on every trigger input set the following parameters:

 Within the System Mode menu:

o Set the mode to Burst.
o Set the number of pulses that is desired for each input signal.
o Press the Page button and set the T0 pulse to the period desired between pulses.

 Within the Trigger menu:

o Select the Triggered mode.
o Set the trigger threshold level to ~50% of the incoming signal.
o Select either rising or falling edge for the unit to trigger on.

Pressing the Run/Stop button will arm the unit. Once the unit is armed it will generate a set of

pulses for every external trigger received. The units’ timer is reset at the end of a burst and will

generate another set of pulses upon receiving a new trigger. Triggers that occur in the middle of a
burst will be ignored. Pressing the Run/Stop key again will disarm the unit.

Start a Continuous Stream of Pulses Using the External Trigger

The external trigger may be used to cause the unit to start generating pulses by setting:

 Within the System Mode menu select Continuous mode.
 Within the Trigger menu:

o Select the Triggered mode.
o Set the trigger threshold level to ~50% of the incoming signal.
o Select either rising or falling edge for the unit to trigger on.

Pressing the Run/Stop button will arm the unit. Once the unit is armed it will start generating pulses
after an external trigger is received. Triggers that occur after the initial trigger will be ignored.
Pressing the Run/Stop key again will disarm the unit.

7. Programming the 9530/8530

Personal Computer to Pulse Generator Communication

The 9530/8530 has three standard interfaces which are RS-232, USB, and an Ethernet port. All menu
settings can be set and retrieved over the computer interface using a simple command language. The
command set is structured to be consistent with the Standard Commands for Programmable
Instruments (SCPI). Although due to the high number of special features found in the 9530/8530,
many of the commands are not included in the specification. The syntax is the same for all interfaces.
The amount of time required to receive, process, and respond to a command at a Baud rate of
115200 is 10 ms. Sending commands faster than 10 ms may cause the unit to not respond properly.
It is advised to wait until a response from the previous command is received before sending the next
command.

WARNING: When communicating with the unit (USB, Serial or Ethernet), avoid sending any

commands that include the “*” character as the unit is booting up. This may result in an undesired

lockup of the instrument.

RS-232 Interface Overview

The serial port is located on the back of the 9530 and uses a 9-pin D-type connector with the
following pinout (as viewed from the back of the unit):

The serial port parameters should be set as follows:

*Note: The default baud rate for the RS-232 is 115200.

9530/8530 Manual Version 4.8 Page 31

USB Interface Overview

The USB interface is standard on the 9530. The interface is a Plug-n-Play capable interface. USB
communication is achieved by using a mapped (virtual) COM port on the PC. The driver installation
executable will obtain an unused COM port number, install the USB drivers, and make that COM port
number available for typical RS-232 communication to the pulse generator. HyperTerminal or other
common software may be used.

When communicating through the mapped COM port over USB, the baud rate for the
communication port used by the USB chip must match the baud rate for the COM port on the PC.
Access to the USB port baud rate is done using the SCPI command
:SYSTem:COMMunicate:SERial:USB “n” command; where “n” is the desired communication speed.
This parameter can be accessed via any communication method. The default baud rate for USB is

38400.

USB communication notes:

 The correct drivers must be installed on the on the personal computer before

communication can be accomplished via USB.

 The Baud Rates on the PC and the pulse generator must match for successful

communication.

 The USB port’s Baud Rate on the pulse generator can be set using the SCPI

command SYSTem:COMMunicate:SERial:USB “n”, where “n” can be: 4800, 9600
19200, 38400, 57600, or 115200.

 USB 2.0 specification is used. The USB cable can be removed without “ejecting” the

device in the operating system environment.

Ethernet Interface Overview

An Ethernet interface is also standard on the 9530. Refer to Appendix C included at the end of this
manual for more information about the Ethernet Interface and Operation.

Programming Command Types and Format

The 9530/8530 Pulse Generator uses two types of programming commands: IEEE 488.2 Common
Commands and Standard Commands for Programmable Instruments (SCPI). The format is the same
for all interfaces. HyperTerminal (in Windows) or any other generic terminal program may be used to
interactively test the commands using the RS-232 interface. The format of each type is described in
the following paragraphs.

Line Termination

The pulse generator uses text-style line terminations. When a command is sent to the unit, the
firmware is programmed to read characters from a communication port until it reads the line
termination sequence.

The command string is parsed and executed after reading these characters. These characters ar e

Page 32 9530/8530 Manual Version 4.8

the “carriage return” and “linefeed”. They are ASCII character set values 13 and 10 respectively (hex

*RST <cr><lf>

*RCL 1 <cr><lf>

*IDN? <cr><lf>

SCPI Format

0x0D and 0x0A). All command strings need to have these characters appended.

When the pulse generator responds to a command, whether it is a query or a parameter change, it
also appends its return strings with these characters. Coded applications could use this behavior to
know when to stop reading from the unit. However, if the “echo” parameter is enabled, there will be
two sets of line terminators, one following the echoed command string, and one following the pulse
generator’s response.

*Note: The pulse generator will echo commands on the RS-232 serial port only.

The pulse generator responds to every communication string. If the communication string is a query,
the unit responds with the queried response (or error code) followed by the line terminators. If the
communication string is a parameter change, the response is “ok” (or error code) followed by the line
terminators. For this reason, it is not recommended that multiple commands be stacked together into
single strings as is common with some other types of instruments. It is recommended that the coded
application send a single command in a string and follow immediately by reading the response from
the unit. Repeat this sequence for multiple commands.

IEEE 488.2 Common Command Format

The IEEE 488.2 Common Commands control and manage generic system functions such as reset,
configuration storage and identification. Common commands always begin with the asterisk (*)
character and may include parameters. The parameters are separated from the command
pneumonic by a space character. For Example:

SCPI Command Keywords

The commands are shown as a mixture of upper and lower case letters. The upper case letters
indicate the abbreviated spelling for the command. You may send either the abbreviated version or the
entire keyword. Upper and/or lower case characters are acceptable.

For example, if the command keyword is given as POLarity, then POL and POLARITY are both
acceptable forms; truncated forms such as POLAR will generate an error; polarity, pol, and
PolAriTy are all acceptable as the pulse generator is not case sensitive.

*Note: The unit by default is not case sensitive, but if it is wished to have the system only

respond to capitalized commands see the command list below.

SCPI Command Format

SCPI commands control and set instrument specific functions such as setting the pulse width,
delay, and period. SCPI commands have a hierarchical structure composed of functional
elements that include a header or keywords separated with a colon, data parameters, and
terminators. For example:

9530/8530 Manual Version 4.8 Page 33

:PULSE1:STATE ON <cr> <lf>

:PULSe1:WIDTh 0.000120 <cr> <lf>

:PULSe:POL NORMal <cr> <lf>

SCPI Query Format

:PULSE1:STATE? <cr><lf>

Will return

1<cr><lf>

:PULSE1:WIDTH? <cr><lf>

Will return

0.000120000 <cr><lf>

:PULSE1:POL? <cr><lf>

Will return

NORM <cr><lf>

<Numeric Value>

Accepts all commonly used decimal representation of
numbers including optional signs, decimal points, and
scientific notation:

For Example: 123, 123e2, -123, -1.23e2, .123, 1.23e-2,

1.2300E-01

Any parameter may be queried by sending the command with a question mark appended. For
example:

SCPI Keyword Separator

A colon (:) must always separate one keyword from the next lower-level keyword. A space must be
used to separate the keyword header from the first parameter.

SCPI Optional Keywords

Optional keywords and/or parameters appear in square brackets ( [ ] ) in the command syntax.
Note that the brackets are not part of the command and should not be sent to the pulse generator.
When sending a second level key word without the optional keyword, the pulse generator assumes
that you intend to use the optional keyword and responds as if it had been sent.

SCPI Specific and Implied Channel

Some commands, such as PULSe, allow specifying a channel with an optional numeric keyword
suffix. The suffix will be shown in square brackets [ 1 / 2 ]. The brackets are not part of command
and are not to be sent to the pulse generator. The numeric parameters correspond to the following
channels: 0 = T0, 1 = ChA, 2 = ChB, etc. Only one channel may be specified at a time.

If you do not specify the channel number, the implied channel is specified by the :INSTrument:SELect
command or the last referenced channel.

After power-up or reset (*RST) the instrument will default to channel #1.

SCPI Parameter Types

The following parameter types are used:

Page 34 9530/8530 Manual Version 4.8

Represents a single binary condition that is either true or false.
True is represented by a 1 or ON; false is represented by a 0 or
OFF. Queries return 1 or 0.

Error Codes

The unit responds to all commands with either:

ok <cr><lf> or ?”n “<cr><lf>

Where "n" is one of the following error codes:

1. Incorrect prefix, i.e. no colon or * to start command.

2. Missing command keyword.

3. Invalid command keyword.

4. Missing parameter.

5. Invalid parameter.

6. Query only, command needs a question mark.

7. Invalid query, command does not have a query form.

8. Command unavailable in current system state.

Ethernet Interface Overview

*Note: See also Appendix D for more on the Ethernet interface

The Ethernet module used is a “Digi Connect ME” module supplied by Digi Connectware, Inc.
There are several ways to successfully communicate with the pulse generator over Ethernet. The
two most popular methods are raw TCP/IP (such as LabVIEW or programming with VISA libraries)
and by mapping a PC COM port using the Dig i Connectware’s “Realport Drivers”.

Whatever method of Ethernet communication is ultimately desired, the utilities supplied by Digi
Connectware (included on the CD shipped with the Pulse Generator) will be critical to
implementing the communications. Please install the following utilities:

Ethernet Communication Notes:

 The Digi Connectware’s “Digi Device Discovery” can be used to determine what IP

address was assigned by the local DHCP server (if any).

 “Digi Device Discovery” can also be used to open a web interface to the Ethernet

module. Simply double-click on the IP address that is displayed in the Digi Device
Discovery utility.

 Username: “root”
 Password: “dbps”

 If a mapped COM port is the desired communication method, the Digi Connectware’s

“Realport Drivers” setup must be used to install the COM port on the PC. The virtual COM

port is then local to the computer it was installed on. Please refer to the Digi Connectware
documentation supplied on the CD, or call Quantum Composers Technical Support.

 The pulse generator’s SCPI default baud rate on the Ethernet port is 115200 and

should not be changed for communication, whether or not a mapped COM port is used.
The virtual COM port on the PC should be set to a baud rate of 115200.



Echo functionality is not available on th e Ethernet port.

Page 48 9530/8530 Manual Version 4.8

11. Appendix D - Ethernet Connectivity

The Ethernet module used in Quantum Composers’ pulse generators is a “Digi Connect ME”
device manufactured by Digi International, Inc. It supports virtually all practical Ethernet
communication methods. A set of utilities and documentation by Digi is included on the CD
shipped with the pulse generator.
This discussion assumes that the Digi utilities included with your pulse generator and National

Instruments VISA (version 3.3 in this procedure, see National Instruments’ website) are installed.

The procedures discussed have been prepared using Windows XP service pack 2.

Determining IP address

The Digi module has been reset to factory defaults before it left the manufacturing facility. In this
mode, it is ready to be assigned an IP address by the local DHCP server. If a crossover cable is
being used, the Ethernet device will assume a default IP address.

The Digi utility “Digi Device Discovery” can be used to determine the IP address that is currently
assigned to the Ethernet module. Hit “Start, All Programs, Digi Connect, Digi Device Discovery”.

When the utility opens, it scans the LAN looking for Digi Ethernet modules. It may take a minute
after plugging in or powering the Ethernet module before the LAN negotiates the connection with
the Digi module. Hit “Refresh View” in the left column after a minute or so if the utility fails to see
the unit when you start it. When the utility sees the Digi device, it will display it in the list (Figure

1).

Figure 1: Digi Device Discovery utility displaying Digi module discovered on the LAN

Note the IP address for use later. A static IP address can be set using the “Configure network
settings” link in the left hand column. From this point, a web interface can be opened, allowing

access to configuration options for the Digi module. Select “Open web interface” under the device
tasks on the left hand column of the Digi Device Discovery software.
You will be required to enter the following username and password:

 Username: “root”
 Password: “dbps”

9530/8530 Manual Version 4.8 Page 49

The Digi Connect ME Configuration and Management home page will be displayed (Figure 2).

Figure 2: Configuration Home page

From the home page select “Serial Ports” on the left hand side. The serial port configuration page

will be displayed (Figure 3).

Figure 3: Serial Ports page

Select Port 1 from the list of ports. Select TCP Sockets from the list of available profiles and click
on apply at the bottom of the page. The TCP Sockets profile settings will then be displayed. Be

sure that the box next to “Enable Raw TCP access using TCP Port:” is selected and note the port

number. By default the port number is 2101. If any settings were changed click on apply at the

bottom of the Port Profile Settings section. Next, select the “Basic Serial Settings” section located
below the “Port Profile Settings” section. If the product is a 9500+ select 9600 as the baud rate, all

other models need to be set to a baud rate of 115200 (Figure 4).

Page 50 9530/8530 Manual Version 4.8

Figure 4: Baud rate settings

Click on apply after changing the baud rate. Select “Logout” from the bottom of the left hand
column. After logging out power cycle the instrument. Use the Digi Device Discovery software to
see if the IP address of the unit appears again. Once the unit has been identified the unit is ready
for communication.

Testing Ethernet Communication

Ethernet communication to the pulse generator can be tested using a utility that is installed with

National Instruments’ (current) VISA libraries.
After determine the IP address for the unit, “VISA Interactive Control” can be used to send and

receive command strings to and from the pulse generator. Hit “Start, All Programs, National

Instruments, VISA, VISA Interactive Control” (Figure 5).

Figure 5: Typical path to VISA Interactive Control utility

9530/8530 Manual Version 4.8 Page 51

When this utility opens, it displays local resources found. TCPIP resources are typically not
shown in this window. However, the resource string can be successfully entered manually in the
“Resource to Open” field (Figure 6). The resource string for Digi Connect Ethernet Modules in
Quantum Composer pulse generators needs to be formatted as follows:
TCPIP0::<IP address>::2101::SOCKET

Or, for example:

TCPIP0::192.168.1.44::2101::SOCKET
A session window will open allowing access

to communication parameters and read and
write buffer access and control (Figure 6).
Quantum Composer pulse generators
support SCPI formatted command strings.
For these units, command strings and
responses are both terminated with text-style
line terminations, a carriage return and
linefeed pair. These are ASCII characters
number 13 and 10 respectively. They are
represented in this utility (and in many other
contexts) as “\r\n”.

Figure 6: Session window for TCPIP resource

In hexidecimal, these are represented as “0x0D” and “0x0A”, respectively. When sending

command strings to the pulse generator, strings need to be terminated with a carriage return and
linefeed pair. Without this line termination, the pulse generator will not execute commands, but
continue to wait for more characters until it sees this string termination sequence.

Tab over to the “Write” tab (Figure 7).

Page 52 9530/8530 Manual Version 4.8

Figure 7: Commands can be sent to the pulse generator from the "Write" tab buffer

The “Buffer” field can be edited to send any valid command to the pulse generator. Hit “Execute”

to send the “*IDN?” command. Now tab over to the “Read” dialog (Figure 8).

Figure 8: Return string from *IDN? query

Successive iterations between “Write” and “Read” operations can be accomplished from here.
Keep in mind that it is always best to follow each “Write” command immediately with a “Read”

command, whether the commands are generated from a utility such as this, or from a more
complex coded application. The pulse generator is designed to respond to every command line

with either the result of a query (ie, “:pulse1:width?\r\n” could return “0.000100000”), or a simple
“ok\r\n” to acknowledge a successful parameter change. If a “Read” command does not follow

each “Write” command, the read (output) buffer in the pulse generator can overfill and become

corrupt.
Many applications may need a communication mechanism no more sophisticated than what can

be achieved with this simple utility. At the very least, this tool can be used to verify that the pulse

12. Appendix E - Dual Trigger Input

DT15 Dual Trigger Module

*Note: Dual Trigger Mode and Incrementing mode are mutually exclusive.

This module option allows the “Gate” input to function as a second trigger input. For consistency,
the enabling menu for this option is located under the “Trig” menu structure. Once the dual trigger
mode is enabled, both the “Gate” and “Trig” inputs can act as trigger inputs.

Adjustments for the “Gate” functioning as a trigger input are located under the “Gate” menu
structure. The voltage threshold level and trigger edge for the “Gate” input can be adjusted from this
menu. The “Gate” trigger edge choice is only available when in dual trigger mode.

Once dual trigger functionality is enabled on the unit, each channel can be assigned to either of the
trigger inputs. The default trigger source for each channel is the “Trig” input. The trigger source
selection is accessed in the secondary channel menus. To access this menu, press the button for
the channel of interest twice. Continue to press then the Page button until the menu page with “Ch
Gate:” and “TrigSrc:” appears. Use th e “Next” button to place the cursor on the “TrigSrc” line and
use the up/down arrows to change to the desired trigger source.

14. Appendix G - Increment Mode

Using the Increment System Mode

*Note: Dual Trigger Mode and Incrementing mode are mutually exclusive.

Also to get the first incremented pulse the :PULSe0:IRESet 1 command must be sent,
otherwise the pulse will not get incremented.

The System Increment modes are a pair of special modes, which allow the delay and width of each
channel to be incremented at the end of a burst of pulses. Each channel is independent and each
may be set with different initial values and different values for the step size for both the delay and the
pulse width.

There are two incrementing modes, Burst Increment and Duty Cycle Increment. In the Burst
Increment mode, each start command or external trigger produces a burst of pulses. At the end of
the burst the appropriate delays and pulse widths are incremented and the instrument is armed for
the next start command. In the DC Increment (Duty Cycle) mode the output is started as with the
normal duty cycle mode. At the end of each cycle the delays and pulse widths are incremented.
This continues for the number of cycles defined by the Cycle parameters. The modes are selected
from the system mode menu. The step sizes are specified in the advanced channel menus.

9530/8530 External Clock Operation

The 9530 pulse generator has a special external clock circuit that allows for external clock
synchronization when using clock sources that have very narrow pulse widths and amplitudes.
The circuit was designed to be used on the output of a photo-diode or equivalent current
source. The clock function will still operate if a voltage source is used if the parameters stated
below are observed.

Page 60 9530/8530 Manual Version 4.8

*Note: These specifications are preliminary and subject to change.

Using the external clock function:

 Enter the system menu pages and find the clock menu page. Enter the clock source

menu by pressing the page button until the clock source page is reached.

 Select the source to External Osc or External PLL.
 Adjust the threshold level to trigger between 10% and 30% of the High-Z input

amplitude of the external clock source. For example when clock source is connected

to a 1MΩ input of an oscilloscope.

 Adjust the rate to match the frequency of the external clock source.
 A “?” will appear if the system does not lock onto the external clock source when in

External PLL mode. Possible causes are:

o Threshold level not adjusted correctly.
o External clock source not present.
o External clock has excessive jitter.
o Amplitude of external clock is changing.

16. Appendix I – 8530 Board Level Option

8530 Board Level Connection Information

8530 Board Level Overview

The 8530 is a board level option based on the 9530 series pulse generator. The
specifications, communications, and overall functionality of the 8530 are the same as
described for the 9530 series. The 8530 is available with either 4 or 8 independent outputs
that can be used for synchronizing multiple events. With the 8530 all communications will
take place through USB, Ethernet, or RS-232 as there is no display or keypad for
interactions. The guide for standard SCIP communications with the 8530 unit can be found
above in the 9530 standard manual. As with the 9530, the 8530 is capable of generating
multiple pulses for all applications; but additional setup is required before even basic
pulsing may begin.
