Measurement
Description
Voltage Source
Select which channel the voltage waveform is on.
Current Source
Select which channel the current waveform is on.
Harmonics
Specify the number of harmonics to calculate. whether to calculate harmonics on the
voltage or the current waveform, and how to determine the frequency of the primary
waveform.
Standard
Select between general harmonics analysis or testing to a specific standard, such as IEC
61000-3-2 Class A or MIL-STD-1399 Section 300A.
Harmonics Source
Specify whether to calculate harmonics on the voltage or the current waveform.
Frequency Reference
Select how to determine the frequency of the primary waveform. Choices are None, IEC
61000-3-2, V, I, Fixed.
Fixed Reference
Specify the fixed reference frequency of the primary waveform. This control is only
available when Frequency Reference is set to Fixed.
Display
Selects the harmonics to display.
Line Frequency
Select teh line frequency of the DUT .
Class
Select the class from the drop-down list. Available values are A, B, C (Table 1), C (Table 2),
C (Table 3), and D.
Observation Period (OP)
Enter the observation period.
Set Scale & RL for OP
Sets the scale and record length for the observation period.
Power Factor
