Page 6: Safety Issues
3 Safety Issues Normal use of equipment exposes users to a certain amount of danger from electrical shock because testing must be performed where exposed voltage is present. An electrical shock causing 10 milliamps of current to pass through the heart will stop most human heartbeats. -
Page 7: Product Overview
4 Product Overview The 9730 series combines industry leading QC digital delay methodologies along with high capacity charge banks to generate precisely timed adjustable amplitude current pulses. This ability to generate highly precise current pulses makes this unit ideal for applications that require a high level of accuracy and repeatability. -

Page 23: Operating Instructions
9 Operating Instructions Quick Start – Internal Single Shot Generator Operation Although the 9730 has a powerful set of feature extensions that allow the user to cater it to many unique test setups, the following steps may be followed to quickly generate a single shot internally generated pulse. -
Page 24: Quick Start - Single Shot External Trigger Operation
Quick Start – Single Shot External Trigger Operation To generate a single pulse for single external trigger event, based on the default configuration 0, the following parameters need to be set: Trig Enter the trigger menu by pressing the TRIG key. Change mode to ‘Enabled’. -
Page 25: Wait For Charge
Wait for Charge When the Safety Interlock is properly shorted the instrument will charge up the capacitor banks for each channel (regardless of whether the channel is enabled or not).

Page 30: 10 Programming The 9730
10 Programming the 9730 Personal Computer to Pulse Generator Communication The 9730 comes standard with a RS232 serial and USB interface. An Ethernet interface is available as an option. 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). -
Page 31: Usb Interface Overview
The USB interface is standard on the 9730. Before this type of communication can be used, the appropriate drivers must be installed on the personal computer. These drivers are included on the disc that was shipped with your unit. Please contact Quantum Composers or visit www.quantumcomposers.com for updated installation files and instructions. -
Page 32: Ethernet Interface Overview
• 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 your computer. Please refer to the Digi Connectware documentation supplied on the disc, or call Quantum Composers technical support. Programming Command Types and Format The 9730 Pulse Generator uses two types of programming commands: IEEE 488.2 Common Commands and Standard Commands for Programmable... -
Page 33: Ieee 488.2 Common Command Format
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 the 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 the one following the pulse generator’s response. -

Selects from a finite number of predefined strings. Legacy Command Support In addition to IEEE 488.2 and SCPI formatted commands, the 9730 Series also supports all legacy 971x commands for ease of software migration from the 971x instruments. Legacy commands begins with a ‘$’ symbol with each command keyword separated by a ‘:’... -
