COMMAND REFERENCE 4 - 83
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
µ
s (non-alternating time base).
