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

). 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.

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

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

Pressing 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

pulses at a rate specified

by the Period parameter.
