PROGRAMMING YOUR PULSE GENERATOR
KEY PROGRAMMING COMMANDS
The “Programming Manual for -B Instruments” describes in detail how to connect the pulse generator to your computer, and the programming commands themselves. A large number of commands are available; however, normally you will only need a few of these. Here is a basic sample sequence of commands that might be sent to the instrument after power-up, using the internal trigger source:
*rst sour:func sin frequency 1000 Hz output on volt 50 volt:low -10
(resets the instrument)
(selects a sine wave output)
(sets the frequency to 1000 Hz)
(turns on the output)
(sets the amplitude to 50 V)
(sets the offset to -10 V)
To generate a pulse output, use:
*rst sour:func pulse frequency 1000 Hz pulse:width 10 us pulse:delay 1 us output on volt 50 volt:low -10
(resets the instrument)
(selects a unipolar pulse output)
(sets the frequency to 1000 Hz)
(sets the pulse width to 10 us)
(sets the delay to 1 us)
(turns on the output)
(sets the amplitude to 50 V)
(sets the offset to -10 V)
To amplify an external signal, use:
*rst sour:func amp output on volt 50 volt:low -10
(resets the instrument)
(enables the amplifier mode)
(turns on the output)
(sets the gain to 50 / 2 = 25)
(sets the offset to -10 V)
To generate a burst of sine wave cycles (requires -PANB option), use:
*rst sour:func sin frequency 1000 Hz pulse:count 7
(resets the instrument)
(selects a sine wave output)
(sets the frequency to 1000 Hz)
(disables continuous output mode – no burst though, because the amplitude is zero)
output on volt 50 pulse:count 7
(turns on the output)
(sets the amplitude to 50 V)
(generates a burst of 7 sine wave cycles)
These commands will satisfy 90% of your programming needs.
