[:SENSe]:BANDwidth|BWIDth Subsystem

This subsystem contains commands related to the filter bandwidth of the instrument.

Resolution Bandwidth

[:SENSe]:BANDwidth|BWIDth[:RESolution] <freq>

[:SENSe]:BANDwidth|BWIDth[:RESolution]?

Sets the resolution bandwidth.

Note that using this command turns the automatic resolution bandwidth setting OFF.

Factory Preset / *RST:	3 MHz
Range:	10 Hz to 3 MHz in a 1:3 sequence
Default Unit:	Hz
Front Panel Access:	BW, RBW
See Also:	[:SENSe]:BANDwidth|BWIDth[:RESolution]:AUTO

 

Resolution Bandwidth Coupling

[:SENSe]:BANDwidth|BWIDth[:RESolution]:AUTO OFF|ON|0|1

[:SENSe]:BANDwidth|BWIDth[:RESolution]:AUTO?

Sets the state of the coupling of the resolution bandwidth to the frequency span.

Setting the value to ON or 1 will result in the resolution bandwidth being coupled to the span. That is, when the span changes, the resolution bandwidth changes.

Setting the value to OFF or 0 will result in the resolution bandwidth being un-coupled from the span. That is, changing the span will not change the resolution bandwidth. When this command is issued, the resolution bandwidth setting itself will not change.

The default value is ON. That is, sending :SENS:BAND:RES:AUTO is equivalent to sending :SENS:BAND:RES:AUTO ON.

Factory Preset / *RST:	ON
Front Panel Access:	BW, Auto RBW

Resolution Bandwidth to Span Ratio

[:SENSe]:BANDwidth|BWIDth[:RESolution]:RATio <number>

[:SENSe]:BANDwidth|BWIDth[:RESolution]:RATio?

Sets the ratio of the resolution bandwidth to the span for use when the resolution bandwidth to span coupling is enabled.

Note that the front panel interface sets the inverse ratio: the span to the resolution bandwidth.

Factory Preset / *RST:	0.0033
Range:	0.00001 to 1
Front Panel Access:	BW, Span/RBW (note that this is the inverse ratio)
See Also:	[:SENSe]:BANDwidth|BWIDth[:RESolution]:AUTO

 

Video Bandwidth

[:SENSe]:BANDwidth|BWIDth:VIDeo <freq>

[:SENSe]:BANDwidth|BWIDth:VIDeo?

Sets the video bandwidth.

Note that using this command turns the automatic video bandwidth setting OFF.

Factory Preset / *RST:	1 MHz
Range:	1 Hz to 3 MHz in a 1:3 sequence
Default Unit:	Hz
Front Panel Access:	BW, VBW
See Also:	[:SENSe]:BANDwidth|BWIDth:VIDeo:AUTO

 

Video Bandwidth Coupling

[:SENSe]:BANDwidth|BWIDth:VIDeo:AUTO OFF|ON|0|1

[:SENSe]:BANDwidth|BWIDth:VIDeo:AUTO?

Sets the state of the coupling of the video bandwidth to the resolution bandwidth.

Setting the value to ON or 1 will result in the video bandwidth being coupled to the resolution bandwidth. That is, when the resolution bandwidth changes, the video bandwidth changes.

Setting the value to OFF or 0 will result in the video bandwidth being un-coupled from the resolution bandwidth. That is, changing the resolution bandwidth will not change the video bandwidth. When this command is issued, the video bandwidth setting itself will not change.

The default value is ON. That is, sending :SENS:BAND:VID:AUTO is equivalent to sending :SENS:BAND:VID:AUTO ON.

Factory Preset / *RST:	ON
Front Panel Access:	BW, Auto VBW
See Also:	[:SENSe]:BANDwidth|BWIDth:VIDeo:RATio

 

Video Bandwidth to Resolution Bandwidth Ratio

[:SENSe]:BANDwidth|BWIDth:VIDeo:RATio <number>

[:SENSe]:BANDwidth|BWIDth:VIDeo:RATio?

Sets the ratio of the video bandwidth to the resolution bandwidth for use when the video to resolution bandwidth coupling is enabled.

Note that the front panel interface sets the inverse ratio: the resolution bandwidth to the video bandwidth.

Factory Preset / *RST:	0.33
Range:	0.00001 to 1
Front Panel Access:	BW, RBW/VBW (note that this is the inverse ratio)
