HP WaterSkis E1412A, WaterSkis E1312A manual DETectorBANDwidth

DETector:BANDwidth

[SENSe:]DETector:BANDwidth <bw> selects the slow, medium or fast filter based on the bandwidth you specify. The multimeter uses these three different filters which enable you to either optimize low frequency accuracy or achieve faster ac settling times on ac voltage or ac current measurements.

Parameters

Parameter Name	Parameter Type	Range of Values	Default Units
<bw>	numeric	320200MINMAX	none

--Specifying a parameter less than 200 but greater than 20 selects the 20Hz filter.

--Specifying a parameter less than 20 but greater than 3 selects the 3Hz filter.

--Specifying a parameter greater than 200 but not greater than 300E+03 (300kHz) selects the 200Hz filter.

--Any value greater than 300kHz will cause a “Data out of range” error. The maximum range for all three filters is 300kHz. Specify the lowest frequency expected in the input signal. The multimeter selects the appropriate filter based on the table below.

Comments • The following table lists the filter frequency range and the settling time for making measurements.

AC Voltage or Current	AC Filter	Max Reading Rate for
Input Frequency	Selected	Adequate Settling
3Hz to 300kHz	Slow filter	1 reading/7 seconds
20Hz to 300kHz	Medium filter	1 reading/second
	(default)
200Hz to 300kHz	Fast filter	10 readings/second

•The ac filter selection is stored in volatile memory and returns to the 20Hz filter (medium) when power is removed or after a module reset. The upper limit on all three filters is 300kHz.

The slow filter is 3Hz, the medium filter is 20Hz and the fast filter is 200Hz.

The CONFigure and MEASure commands select the 20Hz filter.

*RST Condition: DET:BAND 20 (medium filter)

Example Set the ac Signal Filter for Fast Measurements From 200Hz to 300kHz

DET:BAND 200 Selects the fast filter.
