VNA Master™Programming Manual : VNA Commands : [:SENSe]:SWEep Subsystem
 
[:SENSe]:SWEep Subsystem
This subsystem includes commands that affect the sweep parameters of the instrument.
 
IF Bandwidth
[:SENSe]:SWEep:IFBW
Description
Sets the IF Bandwidth. When the Measurement View is set to VNA, the <freq value> in Hz must be one of the following 13 values:
100000|50000|20000|10000|5000|2000|1000|500|200|
100|50|20|10
When the Measurement view is set to FIELD, the <freq value> in Hz must be one of the following 3 values:
100000|1000|10
The query form of this command returns the frequency in Hz.
Syntax
[:SENSe]:SWEep:IFBW <freq value>
[:SENSe]:SWEep:IFBW?
Cmd Parameter
<char> <freq value>
Query Response
<char> <freq value>
Default Value
10000
Default Units
Hz
Range
100 to 100000 Hz
Example
Sets the IF Bandwidth frequency to 200 Hz:
:SENS:SWE:IFBW 200
Sets the IF Bandwidth frequency to 100 kHz:
:SENS:SWE:IFBW 100000

Number of Sweep Points
[:SENSe]:SWEep:POINts
Description
Sets the total number of measurement points per sweep. Note that a sweep with a lower number of data points will complete in less time than a sweep with a higher number of data points.
Syntax
[:SENSe]:SWEep:POINts <integer>
[:SENSe]:SWEep:POINts?
Cmd Parameter
<NR1> <integer>
Query Response
<NR1> <integer>
Default Value
201
Range
2 to 4001
Front Panel Access
Shift‑3 (Sweep), Data Points
Sweep Type
[:SENSe]:SWEep:TYPE
Description
Sets the sweep type. The query version of this command returns “SING” if current sweep is set to single sweep, and returns “CONT” if set to continuous sweep. Note that setting the sweep type to SINGle sets the sweep to hold.
Syntax
[:SENSe]:SWEep:TYPE SINGle|CONTinuous
[:SENSe]:SWEep:TYPE?
Cmd Parameter
<char> SINGle|CONTinuous
Query Response
<char> SING|CONT
Default Value
CONT
