SENSe:SWEep:TIME

Syntax: SENSe:SWEep:TIME <NRf> MINimum MAXimum

<NRf>

The sweep time in seconds.

MINimum

Selects the minimum possible sweep time.

MAXimum

Selects the maximum possible sweep time.

Query form: SENSe:SWEep:TIME? [MINimum MAXimum]

Response: <NR3>

<NR3>

The sweep time expressed in seconds.

If MINimum was specified, the minimum possible value is returned.

If MAXimum was specified, the maximum possible value is returned.

Description:

This command sets the time base of a sweep for all input channels in seconds. The time base of a sweep is the time duration of one complete trace acquisition. Together with the number of trace points (TRACe:POINts), the SENSe:SWEep:TIME command determines the Main Time Base (MTB). The MTB is expressed in seconds per division. Since there are 50 points in each division (horizontally), the MTB can be calculated from the following equation:

MTB = 50 * SENSe:SWEep:TIME / (TRACe:POINts - 1)

In the analog mode the main time base is put in the variable mode. In the digital mode the sweep times are limited by permitted MTB values according to the following table:

Note:

If 2 or more channels are switched on in the real time mode, the time

 

base range is limited to 10 μs (non-alternating time base).
