Agilent Technologies 85330A service manual Event Trigger, Receiver Ready, Switch List Loop

Programming

To Use Run-Time Control Mode

Event Trigger

If TTL triggering has been selected, the 85330A waits for an Event Trigger pulse before sending a measurement trigger to the receiver. If IMM triggering has been selected, the measurement trigger is sent to the receiver immediately. The trigger mode is selected using RUNT:EVEN:TRIG. If a timeout occurs while waiting for Event Trigger, run-time is aborted and an error message is issued. The timeout duration can be set using the RUNT:TIME:EVEN command.

Receiver Ready

The 85330A now waits for the Receiver Ready signal (from the receiver), indicating that the 8530A is ready to take another measurement. If a timeout occurs while waiting for Receiver Ready, run-time is aborted and an error message is issued. The timeout duration can be set using the RUNT:TIME:REC command.

Switch List Loop

If all switch settings defined in RUNT:SWIT:SCAN have not been measured, the next switch state is asserted and the settling time delay occurs. Another measurement trigger is sent to the receiver, and the 85330A waits for Receiver Ready again. This loop continues until all defined switch states have been measured.
