7. Operating the 9250
Normal Internal Rate Generator Operation
The 9250 has a complete set of functions providing a number of modes of operation for the
internal or “System” rate generator (T
0
). Most of these functions can be ignored if a simple
continuous stream of pulses is required. Starting from the default settings, which can be
restored by recalling configuration 0, the following parameters need to be set in the 9250
application:
Pulse Width, Delay Enter the required pulse width and delay found in the
Channel section. Repeat for each output channel.
T
0
Period Set the desired pulse Period found in the System section.
Enable
*Note: In general the pulse delay + the pulse width + 75 ns (for a
hardware reset for any channel) must be less than the T
0
period.
Enable the corresponding channels by clicking “Enabled”
in the Channel section.
Start Press the
unit’s Run/Stop button to start generating
pulses
Stop Press the unit’s Run/Stop button once again to stop
generating pulses.
Continuous Mode
Pres
sing the unit’s Run/Stop button starts and stops a continuous pulse stream at the
rate specified by the Period parameter. This corresponds to the default output mode for
most pulse generators. To generate a continuous stream of pulses, set the following
parameters in the 9250 application:

Within the System section:
o Select Continuous mode.
o Set the desired pulse Period.

Within the Channel section:
o Enter the required pulse width and delay. Repeat for each output channel.
o
Enable the corresponding channels by clicking “Enabled” in the 9250 application.
Pressing the unit’s Run/Stop button will now generate a stream of
T
0
pulses at a rate specified
by the Period parameter.
