SENSe Subsystem
Set the resolution bandwidth. This value is ignored if the function is
auto-coupled.
Factory Preset
and *RST: 100.0 kHz for NADC, PDC, cdma2000, W-CDMA
(3GPP), W-CDMA (Trial & Arib), basic, service
500.0 kHz for GSM
2.0 MHz for cdmaOne
Range: 1.0 kHz to 5.0 MHz
Remarks: To use this command, the appropriate mode should be
selected with INSTrument:SELect.
Waveform - Query Actual Resolution Bandwidth
[:SENSe]:WAVeform:BANDwidth:RESolution]:ACTual?
Due to memory constraints the actual resolution bandwidth value may
vary from the value entered by the user. For most applications the
resulting difference in value is inconsequential but for some it is
necessary to know the actual value; this query retrieves the actual
resolution bandwidth value.
Remarks: Implemented for users of Glacier and other applications
that require precise resolution bandwidth readings. To
use this command the appropriate mode should be
selected with INSTrument:SELect.
History: Version A.05.00 or later
Waveform—Resolution BW Filter Type
[:SENSe]:WAVeform:BANDwidth|BWIDth[:RESolution]:TYPE
FLATtop|GAUSsian
[:SENSe]:WAVeform:BANDwidth|BWIDth[:RESolution]:TYPE?
Select the type of Resolution BW filter that is used. This is an Advanced
control that normally does not need to be changed.
FLATtop - a filter with a flat amplitude response, which provides the
best amplitude accuracy.
GAUSsian - a filter with Gaussian characteristics, which provides
the best pulse response.
Factory Preset
and *RST: GAUSsian
Remarks: To use this command, the appropriate mode should be
selected with INSTrument:SELect.
