85330A Multiple Channel Controller 6-13
Programming
To Use Run-Time Control Mode
Switch Settling Time You must specify switch settling time before starting run-time mode. The
default setting is 2
µs.
NOTE If your configuration requires you to use the multiple-parameter display
features of the 8530A, as described in “Single Source Multiple-Frequency
Configuration” on page 6-5, set settling time to 50 µs. This applies to:
• The single source multiple-frequency configuration.
• The dual source multiple-frequency configuration, but only when the
8530A controls the sources.
Applicable command:
RUNTime:SWITch:DELay
TTL Trigger and
Ready Timeouts
Timeout conditions are used for:
• Event triggering (EVENT TRIG)
• Receiver ready (RCVR READY)
• Source ready lines (SRC 1 READY and SRC 2 READY)
Timeouts enable the 85330A to recover from possible error conditions.
The timeout for the event trigger input has two separate timeout settings:
• One timeout is for the first trigger being issued.
• The other timeout is for subsequent triggers.
If the expected signal is not received before the specified time, the 85330A
will exit from run-time operation and issue an error.
Applicable commands:
• RUNTime:TIMEout:EVENt
• RUNTime:TIMEout:RECeiver
• RUNTime:TIMEout:SOURce
