Enhanced Options
Shown below in Figure 6.5 is the
“Enhanced Options” section of the 9250 application followed
by detailed descriptions of the individual functions:
Figure 6.5 –9250 Application: System Parameters

Shot Counter: The “Shot Counter” can be set up to count the system (T
o
) or any of the
available channel outputs. This counter is a 32 bit counter that can be enabled and
reset by the user by means of the “Enable” selection and “Clear” button.

Period Counter: The “Period Counter” measures the period of the incoming external
trigger pulses. The period counter must be first enabled by means of the “Enable”
selection. This counter can average up to 15 periods for greater accuracy. This is
controlled under the “Periods to Average.” If the period counter is selected to run in
manual mode (“Auto Update” not enabled), it will latch the incoming period
measurement and hold the reading. If “Auto update” mode is selected, the reading will
constantly be updated as long as external triggers are applied. The displayed
measurement may be cleared at any time by means of the “Clear” button.

Sync Update: The ”Sync Update” allows for the channel timers (delays and widths) to
be manually updated so that all changed values are applied synchronously. Normally
when any width or delay is changed, it is automatically applied. When Synchronous
Update Mode is selected to be enabled, all channel width and delays can be adjusted
and then
updated simultaneously via the “Update” button (or SCPI command).

Duty Cycle Counts:
The “Duty Cycle Counts” value sets the number of cycles the duty
cycle sequence will execute. If set at 0, the cycles will continue until stopped by the
user. Again, th
is feature can be thought of a “burst” for the duty cycle mode.
