Switch Settling Time | Agilent Technologies 85330A specification

	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 ∝s.

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 ∝s. This applies to:

TTL Trigger and Ready Timeouts

•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

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
