8 Trigger
8.1 Trigger
8.1.1.15 I (Demodulated)
When I (Demodulated) is selected, the trigger condition is met when the I voltage
crosses the I voltage trigger level.
This trigger type is only valid for measurements that support the I/Q inputs.
The Trigger tab contains the following Trigger Source dependent controls when I
(Demodulated) Trigger is selected:
–
"Prot Frame Aligned" on page 2660
–
"Trigger Delay" on page 2663
–
"Trigger Slope" on page 2667
Additional controls are also present that are not dependent on the selected Trigger
Source.
Example
:TRIG:<meas>:SOUR IDEM
Annunciation I (Demod) (in the Meas Bar)
8.1.1.16 Q (Demodulated)
When Q (Demodulated) is selected, the trigger condition is met when the Q voltage
crosses the Q voltage trigger level.
This trigger type is only valid for measurements that support the I/Q inputs.
The Trigger tab contains the following Trigger Source dependent controls when Q
(Demodulated) Trigger is selected:
–
"Prot Frame Aligned" on page 2660
–
"Trigger Delay" on page 2663
–
"Trigger Slope" on page 2667
Additional controls are also present that are not dependent on the selected Trigger
Source.
Example
:TRIG:<meas>:SOUR QDEM
Annunciation Q (Demod) (in the Meas Bar)
