6.16.14 SENSe:SWEep Subsystem
This subsystem controls the sweep parameters.
The measurement windows are selected by SENSe1 (screen A) and SENSe2 (screen B).
[SENSe<1|2>:]SWEep:TIME 10 µs to 100 s (receiver) | 2.5 ms to 16000 s (frequency domain) | 1 µs to
16000 s (time domain)
This command defines the sweep time in analyzer mode or the measurement time for the bar graph
in receiver mode.,
For receiver, the available time value range is 10 µs to 100 s with a 2-digit resolution (see chapter
"Instrument Functions", section
available time values are different in the frequency domain (2.5 ms to 16000s with span > 0) and in the
time domain (1 µs to 16000 s with span = 0).
The available sweep time values are different in the frequency domain (2,5 ms to 16000s with span >
0) and in the time domain (1 µs to 16000 s with span = 0).
If SWEep:TIME is directly programmed, automatic coupling to resolution bandwidth and video
bandwidth is switched off.
Example:
"SWE:TIME 10s"
Characteristics: *RST value: - (analyzer; AUTO is set to ON)
100 ms (receiver)
SCPI: conform
Mode: R, A
[SENSe<1|2>:]SWEep:TIME:AUTO ON | OFF
This command controls the automatic coupling of the sweep time to the frequency span and bandwidth
settings.
If SWEep:TIME is directly programmed, automatic coupling is switched off.
Example:
"SWE:TIME:AUTO ON"
'Switches on the coupling to frequency span and bandwidths.
Characteristics: *RST value: ON
SCPI: conform
Mode: A
[SENSe<1|2>:]SWEep:COUNt 0 to 32767
This command defines the number of scans started with single scan in receiver mode,
In analyzer mode, this command defines the number of sweeps started with single sweep, which are
used for calculating the average or maximum value. In average mode, the value 0 defines a continuous
averaging of measurement data over 10 sweeps.
Example:
"SWE:COUN 64"
'Sets the number of sweeps to 64.
"INIT:CONT OFF"
'Switches to single-sweep mode.
"INIT;*WAI"
'Starts a sweep and waits for its end.
