85330A Multiple Channel Controller 6-15
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.
