1 INTRODUCTION This manual is designed to help you quickly and easily learn to use your Quantum Composers Model 9700 current pulse generator. The 9700 provides digitally controlled current pulses with currents from 0 - 25 Amps and pulsewidths from 100 µ s to 100ms.
Custom Modifications The 9700 is microprocessor-controlled and employs a flexible and expandable user-interface. New features and operating modes often can be added without hardware modifications by merely modifying the software contained inside the 9700 - contact Quantum Composers for details.
as the on-off switch, fuses, power transformer etc., any time the equipment is connected to an AC outlet, even if the equipment is turned off. 6. Never work alone. Someone should always be nearby to render aid if necessary. Training in CPR first aid is highly recommended.

2 CONTROLS AND CONNECTORS This chapter explains the function of each control and connector on the 9700. Front Panel The front panel contains the most frequently used controls and connectors. Display The 9700 features a backlit liquid crystal display, which displays menu selections and settings.
Left Button For numeric items, this button is used to select which digit in a numeric entry is selected for editing. For other items, or when the left most digit is already selected for numeric items, pressing and holding this button down displays a brief description of the current item.
The charge level indicator illuminates when the capacitor bank is fully charged. The current monitor is an oscilloscope compatible reference voltage to monitor the current pulse, 1A = 100mV. External Trigger Trig In (BNC) -- external signal input to trigger the generation of pulses.
GPIB Port (optional) The GPIB (IEEE 488) interface is available as an option with the 9700. AC Input A standard EIC instrument-type cord should be used.
3 OPERATING INSTRUCTIONS This chapter presents detailed instructions on the operation of the 9700. Overview The 9700 provides digitally controlled, single shot, current pulses. The current is provided by a 3700mF capacitor bank charged to approximately 44V.
Selecting Menu Items The menu items in the 9700 are arranged in a set. Pressing the key will toggle between sets of menus, while the key will toggle between menu items within the current set. Hold down the Left arrow key to receive a short description of the current menu item.
Single Shot Mode During Single Shot operation, one pulse is generated each time the Run key is pressed. The rate at which pulses are produced is totally dependent on how fast the Run key is pressed. The delay of each of the outputs is relative to To (the internal clock).
n :Wid - T n :Pulse Width Each of the two (2) channels has an independent pulse width setting which is set from the Tn:Wid menu, where n = 1, 2. Pulsewidths from 100 µ s to 100ms may be selected with a resolution of 200ns. *See custom features for Long Pulse option specifications.
Shot Counter The 9700 includes a nine (9) digit shot counter. The maximum count displayed is 4,294,967,295 after which the count rolls over to zero. To manually reset the counter to zero, press the Left or Right arrow key. You will prompted to press the key to verify that you want to zero the counter.

____________________________________________________________________ 4 Computer Interface The 9700 comes standard with an RS232 serial interface; a GPIB (IEEE-488) interface is available as an option. All menu settings can be set and retrieved over the computer interface using a simple command language.
Command Protocol All commands have the following syntax: $<name> <##>CR where P $ indicates a command follows. P <name> is the command name. No spaces are allowed between the $ and the <name> . The name is case sensitive. P <##> is an unsigned integer associated with the command.
where name = a valid command name. This will return an integer followed by a space, carriage return, and a line feed character (ASCII 10). Example - the following command would retrieve the current Cy.
Command List The following table summarizes all the commands: Sets the key click volume level. 0 - 9 VOLUME Sets the character used as a decimal point on the display. 0 = , (comma) 1 = . (period) Fmark, Enables/Disables the RS232 echo. The result string is always sent back.
