SWEep:TIMe <time>(?)
HS Syntax: 1600A<float>(?)
Description
This specifies the time that will take the 3152B to sweep from start to stop frequencies. The time does not
depend on the sweep boundaries as it is automatically adjusted by the software to the required interval. At
the end of the sweep cycle the output waveform maintains the sweep stop frequency setting except if the
3152B is in continuous run mode where the sweep repeats itself continuously.

Description
<time>
1.4e-6 to
40
Numeric
1e-3
Programs the sweep time. Sweep time is programmed
in units of s.
Response
The 3152B returns the current sweep time.
SWEep:DIRection {UP|DOWN}(?)
HS Syntax: 1601A<0|1>(?)
Description
This specifies if the 3152B sweeps from start-to-stop (UP) or from stop-to-start (DOWN) frequencies. Sweep
direction does not affect the sweep time or frequency. At the end of the sweep cycle, the output waveform
normally maintains the sweep stop frequency setting but will maintain the start frequency, if the DOWN option
is selected except if the 3152B is in continuous run mode where the sweep repeats itself continuously.
Parameters

Type
Default
Description
UP
Discrete
UP
Selects the sweep up direction
DOWN
Discrete
Select the sweep down direction
Response
The 3152B returns UP or DOWN depending on the selected direction setting.
SWEep:SPACing {LINear|LOGarithmic}(?)
HS Syntax: 1602A<0|1>(?)
Description
This specifies the sweep step type. Two options are available: logarithmic or linear. In linear, the incremental
steps between the frequencies are uniform throughout the sweep range. Logarithmic type defines logarithmic
spacing throughout the sweep start and stop settings.
Parameters
Name
Type
Default
Description
LINear
Discrete
LIN
Selects the linear sweep spacing
LOGarithmic
Discrete
Select the logarithmic sweep spacing
Response
The 3152B returns LIN or LOG depending on the selected spacing setting.
