Scanning Overview

TRIGger

:TIMer {<y >MINMAX}

:TIMer?

Set the scan-to-scan interval (in seconds) for measurements on the channels in the scan list. This command defines the time from the start of one scan sweep to the start of the next sweep. You can set the interval to any value between 0 seconds and 359,999 seconds (99:59:59 hours), with 1 ms resolution. MIN = 0 seconds. MAX = 359,999 seconds.

The :TIM? query returns the scan-to-scan interval in seconds in the form “+1.00000000E+01”.

TRIGger

:COUNt {<x >MINMAXINFinity}

:COUNt?

Select the number of times that the instrument will sweep through the

scan list (a zz is one pass through the scan list). When the specified number of sweeps have occurred, the scan stops. Select a scan count between 1 to 50,000 sweeps, or continuous (INFinity). MIN = 1 sweep. MAX = 50,000 sweeps.

The :COUN? query returns the scan count in the form “+1.00000000E+01”.

If you specified a continuous scan count, the query command returns 5 “9.90000200E+37”.

ROUTe
:CHANnel:DELay <y	>[,(@<xt	>)]
:CHANnel:DELay? [(@<x	>)]

Add a delay between multiplexer channels in the scan list (useful for high-impedance or high-capacitance circuits). The delay is inserted between the relay closure and the actual measurement on the channel. The programmed channel delay overrides the default channel delay that the instrument automatically adds to each channel.

You can set the channel delay to any value between 0 seconds and

60 seconds, with 1 ms resolution. You can select a different delay for each channel. The default channel delay is automatic; the instrument determines the delay based on function, range, integration time, and ac filter setting (see “Automatic Channel Delays” on page 89).

The :DEL? query reads the channel delay setting in seconds and returns a value in the form “+1.00000000E+00”.
