Description
11-60
This function sets the trigger polarity of the Dual Card pulse generator output
trigger. The trigger is a TTL level output at the same frequency (period) as the
pulse output.
The parameter and return values for this function are listed in
Table 11-68.
Before using this function, make sure the Dual Card pulse generator has been
initialized using the dpulse_init
Description
(long) The trigger polarity:
0 - Negative trigger polarity.
1 - Positive trigger polarity.
Description
No Errors.
Dual Card pulse generator has not been initialized.
All other error cards match up to LPT errors.
This function sets the high voltage value of the output pulse of the Dual Card
pulse generator. The output pulse has two levels, vlow and vhigh. The level is
dependent on the source range and pulse load. The difference between pulse low
and pulse high is the peak-to-peak amplitude of the output pulse.
50 Ω Load:
10 V Range (High Speed) – Pulse high and pulse low can be set between -10
40 V Range (High Voltage) – Pulse high and pulse low can be set between
1 M Ω Load:
10 V Range (High Speed) – Pulse high and pulse low can be set between -20
40 V Range (High Voltage) – Pulse high and pulse low can be set between
