Frequency <strong>Measure</strong>ment Configuration<br />
Features and Functions 3<br />
This section contains information to help you configure the instrument for<br />
making frequency measurements.<br />
Low Frequency Timeout<br />
The instrument uses three different timeout ranges for frequency<br />
measurements. The instrument selects the slow (3 Hz), medium (20 Hz), <br />
or fast (300 Hz) filter based on the input frequency that you specify with<br />
this command for the selected channels.<br />
Applies to frequency measurements only.<br />
Timeouts for Specified Frequency Range Settings:<br />
Input Frequency Timeout<br />
3 Hz to 300 kHz (Slow)<br />
20 Hz to 300 kHz (Medium)<br />
200 Hz to 300 kHz (Fast)<br />
1 second<br />
100 ms<br />
10 ms<br />
The CONFigure and MEASure? commands automatically select the 20 Hz<br />
(medium) filter.<br />
The instrument selects the default 20 Hz (medium) filter after a Factory<br />
Reset (*RST command). An Instrument Preset (SYSTem:PRESet command) or<br />
Card Reset (SYSTem:CPON command) does not change the setting.<br />
Front Panel Operation: DMM or Channel (Configure) > AC FILTER<br />
Remote Interface Operation: Specify the lowest frequency expected in the<br />
input signal on the specified channels. The instrument selects the<br />
appropriate timeout based on the frequency you specify (see table above).<br />
[SENSe:]FREQuency:RANGe:LOWer {3|20|200} [,(@)]<br />
If you omit the optional parameter, the command applies to the<br />
internal DMM.<br />
