    This manual is a reference designed to familiarize you with the Quantum Com- posers 9520 series pulse generator and is arranged so that you can easily find the information you re looking for. Generally, each topic has its own section and no section assumes that you ve read anything else in the manual.

  • Page 8: Safety Issues

    Safety Issues Normal use of test equipment presents a certain amount of danger from electri- cal 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.

    Channel Timer Functions 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, addi- tional start pulses will be ignored until the pulse has been completed (non- retriggerable).
  • Page 17 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. To select the next page, press the channel button again or select the same menu pressing the FUNC key and the channel/menu key again.

    Quick Start - Normal Internal Rate Generator Operation The 9520 has a powerful set of functions providing a number of modes of opera- tion for the internal or System rate generator (T ). Most of these functions can be ignored if a simple continuous stream of pules is required. Starting from the default settings, which can be recalled by recalling configuration 0, the following parameters need to be set: Pulse Width, Delay...

  • Page 33: Channel Timer Overview

    To Use System Burst Mode Function The RUN/STOP button generates a stream of n T pulses, where n is speci- fied by the Burst parameter. The rate is specified in the Rate menu. Pressing the RUN/STOP button while the burst is in process will stop the output. After the burst has been completed, pressing the RUN/STOP button will generate an- other burst.
  • Page 34 Wid: Set the desired pulsewidth. Mode: Select the Normal mode. Pressing the RUN/STOP key will now generate a continuous stream of pulses. To Use Channel Single Shot Function The Single Shot mode generates a single pulse every time the RUN/STOP key is pressed.

  • Page 35: External Input Overview

    Note: Older Quantum Composers pulse generators had a divide-by-n func- tion. The duty cycle mode is a more general case. 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-n factor.
  • Page 36 To Generate a Burst of Pulses on Every Trigger Input To generate a burst of pulses for every external trigger received set the following parameters: -within the Mode menu Mode: Select the Burst mode. Burst: Set the number of pulses to generate in each burst.- within the Rate menu Per: Set the period between pulses.

    The command string is parsed and executed after reading these characters. These characters are the carriage return and linefeed . They are ascii charac- ter set values 13 and 10 respectively (hex 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.
