•
Vrms (Volts) - RMS voltage reading.
•
Irms (Amp) - RMS current reading.
•
Z (Ohms) - Impedance magnitude in Ohms. Note: Z=V/I.
•
Phase (Deg) - The phase in degrees.
•
R (Ohms) – Resistance in Ohms - the real part of impedance (in rectangular coordinates).
•
jX (Ohms) – Reactance in Ohms - the imaginary part of impedance (in rectangular coordinates).
•
P (Watts) - Power in Watts.
Note:
•
Rel P (dBc) - Power relative to the carrier in dBc.
•
Rel Ph – Phase relative to the fundamental in degrees.
Note: This is only reported if relative phase is enabled. See “Enable relative phase measurements” in Stan-
dard Tracking Mode Options.
•
Attn V (dB) - The attenuation applied (in dB) to the voltage channel during this frequency measurement.
•
Attn I (dB) - The attenuation applied (in dB) to the current channel during this frequency measurement.

Note: The Time Plot view displays each dataset over time. The dataset number is displayed on the X-axis.
Reconstructed Waveform View
Figure 9 Data Viewed As a Waveform
Note: The Waveform view displays a single waveform of a fundamental tone constructed from the har-
monic components captured. Waveform reconstruction is only possible if relative phase is enabled. See
“Enable relative phase measurements” in Standard Tracking Mode Options.
