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
o
). 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
Enter the Channel menus by pressing the letter key.
Enter the required pulse width and delay. Repeat for
each output channel.
T
o
Period
Enter the Rate menu by pressing the FUNC keu and
then the RATE key. Set the desired pulse period. Note
that in general, the pulse delay plus the pulse width,
plus a 75ns hardware reset constant, for any channel
must be less than the T
o
period.
Start
Press the RUN/STOP key to start generating pulses.
Stop
Press the RUN/STOP key a second time to stop gen-
erating pulses.
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:
System Mode
Enter the MODE menu by pressing the FUNC key and
then the MODE key. Select Single Shot mode.
Trig
Enter the TRIG menu by pressing the TRIG key. Select
Triggered.
Level
Press the NEXT key until the Level parameter is dis-
played. Set the trigger threshold voltage to approxi-
mately 50% of the trigger signal amplitude.
