Spectrum—Sweep (Acquisition) Time

Language Reference

SENSe Subsystem

Range:

10 Hz to 10.0 MHz (15 MHz when Service mode is

 

selected)

Default Unit:

Hz

Remarks:

The actual measured span will generally be slightly

 

wider due to the finite resolution of the FFT.

 

To use this command, the appropriate mode should be

 

selected with INSTrument:SELect.

Spectrum—Sweep (Acquisition) Time

[:SENSe]:SPECtrum:SWEep:TIME[:VALue] <time>

[:SENSe]:SPECtrum:SWEep:TIME?

Set the sweep (measurement acquisition) time. It is used to specify the length of the time capture record. If the specified value is less than the capture time required for the specified span and resolution bandwidth, the value is ignored. The value is set at its auto value when auto is selected. This is an advanced control that normally does not need to be changed.

Factory Preset

188.0 ∝s

and *RST:

 

15.059 ms, for iDEN mode

Range:

100 ns to 10 s

Default Unit:

seconds

Remarks:

You must be in the Service mode to use this command.

 

Use INSTrument:SELect to set the mode.

 

This command only effects the RF envelope trace.

Spectrum—Sweep (Acquisition) Time Auto

[:SENSe]:SPECtrum:SWEep:TIME:AUTO OFFON01

[:SENSe]:SPECtrum:SWEep:TIME:AUTO

Select auto or manual control of the sweep (acquisition) time. This is an advanced control that normally does not need to be changed.

AUTO - couples the Sweep Time to the Frequency Span and Resolution BW

Manual - the Sweep Time is uncoupled from the Frequency Span and Resolution BW.
