Description
Sync Source Select the synchronization source: U/I/OFF. The overall interval of the signal voltage, current or data
updating cycle can be selected as the synchronization source for measurement.
Freq Filter Set the status of the frequency filter. When “ON” is selected, the frequency filter is turned on. When
“OFF” is selected, the frequency filter is turned off.
Line Filter Set the status of theline filter. When “ON” is selected, the line filter is turned on. When “OFF” is
selected, the line filter is turned off.
Crest Factor Set the crest factor: CF3/CF6
Update Rate Data Updating Rate Setting key: when this key is pressed, the capture interval of the voltage, current,
power and other data, i.e. data updating rate, can be set. When the data updating rate is increased,
rapid load changes of the power system can be obtained. When the data updating rate is decreased,
relative low-frequency signals can be measured. Options of the dataupdating rate:
0.1s/0.25s/0.5s/1s/2s/5s

2.10.2 Crest factor
The crest factor is the ratio of the waveform peak to the effective value. The Measurement Conditions crest factor of
5335B is specified as the times of the crest value which can be input under the rated input conditions. The crest factor
