:SENSe:BANDwidth[:RESolution]

Description

This command gets or sets the receiver bandwidth resolution. It is defined as the bandwidth of the predetection bandpass filtering.

Note

The behavior of this command is the same as the behavior of :SENSe:BWIDth[:RESolution].

Command

Syntax	Parameter
`:SENSe<ch>:BANDwidth[:RESolution]`	<`numeric`>

Parameters	accepted format	allowed suffixes	possible Errors	description
<`ch`>	{ `1` \| `empty` }	`none`	`Invalid channel index`	Currently only one channel is supported. `Empty` means `1` is used as default.
{ <`numeric`> \| `MINimum` \| `MAXimum` }	Valid value range	`Hz`	`Numeric data error`	The bandpass resolution

Valid value range

Not all numeric values are supported. Valid values for the receiver bandwith are listed in the ReceiverBandwidth 'Fields' table. Be aware that the values need to be in Hz (e.g. for a 1Hz receiver bandwith (Hz1 = 1000) use 1Hz (as declared on the left hand side of the table)).

Important

If the specified parameter is out of the allowable setup range, the parameter will be rounded to the nearest possible value.

Query

Syntax	Response
`:SENSe<ch>:BANDwidth[:RESolution]?`	<`numeric`>

Parameters	accepted format	description
<`ch`>	{ `1` \| `empty` }	Currently only one channel is supported. `Empty` means `1` is used as default.

Response value	description
<`numeric`>	value of bandpass resolution in `Hz`

Presets

For presets please refer to Measurement Modes and Default Settings.

Sample usage

Configure and start an S21 sweep measurement with receiver bandpass resolution of 3kHz.

var visaSession = new TcpipSocket(VISA_RESOURCENAME);
visaSession.RawIO.Write(":CALC:PAR:DEF S21\n");
visaSession.RawIO.Write(":SENS:BAND 3kHz\n");
visaSession.RawIO.Write(":TRIG:SING\n");
// wait for the measurement to finish
visaSession.RawIO.Write("*OPC?\n");
visaSession.RawIO.ReadString();
visaSession.RawIO.Write(":SENS:FREQ:DATA?\n");
var frequencyValues = visaSession.RawIO.ReadString();
visaSession.RawIO.Write(":CALC:DATA:SDAT?\n");
var measurementValues = visaSession.RawIO.ReadString();

Python

visaSession.write(':CALC:PAR:DEF S21\n')
visaSession.write(':SENS:BAND 3kHz\n')
visaSession.write(':TRIG:SING\n')
visaSession.query('*OPC?\n')
frequencyValues = visaSession.query(':SENS:FREQ:DATA?\n')
measurementValues = visaSession.query(':CALC:DATA:SDAT?\n')
