Parameter Description
f Frequency of the output signal. Only available for AC voltage
or current output.
Possible values: Any value between 5.0 and 400.0Hz or soft
keys 16.7Hz, 50Hz, 60Hz or 400Hz.
Default: 50Hz
Measurement Measurement mode.
Mode
Possible values: DC, RMS or f-sel. filter. Default: RMS
DC measurement:
Measures the DC part of the signal only.
RMS measurement:
Performs a standard true RMS measurement of the signal.
Frequency selective measurement:
Allows high precision measurement of the fundamental wave
of an applied signal. All frequencies outside the output
frequency plus/minus the filter bandwidth are supressed by at
least 110 dB. This measurement mode is deactivated for
output signal type DC.
See also "B-width" below.
B-width Filter bandwidth for frequency selective measurement. Only
available for measurement mode Freq. sel. filter.
Possible values: 3Hz to 20Hz. Default: 6Hz
Depending on the filter bandwidth selected, the measurement
time can differ considerably. The typical time needed for a
frequency selective measurement depends on the filter
bandwidth as follows:
Filter bandwidth
3Hz
6Hz
Load Only available for AC signal output.
Setting the Load parameter to "on" and specifying the
winding resistance and the unsaturated inductance in the
fields R and L will prevent saturation of the connected CT.
The output generator of the CT Analyzer then keeps the DC
part of the output current at zero using a current regulator
permanently running during the output of AC signals.
Possible values: On or Off. Default: Off
