Filter
Mod Selects filter time in seconds in Modulated mode only
(Numeric) Auto, Off,
2 ms to 16,000 sec
Set the filter time constant for Modulated mode measurements. The
(in 2 ms steps) filter may be set to Off for minimum filtering, Auto for a calculated
optimum filter based on the time base setting or the time constant in
seconds can be entered using any of the numeric entry methods. For
other modes, see Averaging, below.
SENSe[1|2]:FILTer:STATe {OFF, AUTO, ON}
SENSe[1|2]:FILTer:TIMe <0.002 to 15.00> (sec)
Video BW
Pulse, Mod & Stat Selects either the narrowband or wideband detector response
(Toggle) Low, High
Press Chan # > Extensions > Video BW > Low to select a narrowband
sensor detector response that is useful for displaying noisy, low
frequency signals or to reduce carrier feed through. Not all sensor
models have this feature.
Press Chan # > Extensions > Video BW > High to select a wideband
response that is useful for measuring short pulses. The actual detector
bandwidths vary with the sensor model selected.
SENSe[1|2|3|4]:BANDwidth {LOW, HIGH}
Averaging
Pulse Selects the number of samples that are averaged at each point
(Numeric) 1 to 16,384
Press Chan # > Extensions > Averaging to activate this function. Use
any of the data entry controls to select the number of samples to be
averaged at each point of the waveform to produce the waveform
display. Default = 8.
