"FFT Phase Ch2-Ch1, FFT Phase to Refch"
The phase difference between the phase characteristic obtained
from the calculation of the complex FFT for
●
channel 2 and channel 1
●
the channel number specified under the following "Channel"
parameter field and the reference channel specified in the "Ref
Channel" parameter field in the Analyzer Config panel in the case
of a multichannel instrument
of the FFT or Post FFT analyzer measurement function which is dis-
played as Trace A or Trace B over a frequency x-axis.
In contrast to a comparably slow frequency sweep with phase mea-
surement, the phase measurement using FF provides very rapid
phase measurement results.
Figure 5-23: The yellow trace shows the phase characteristic near the 10 kHz fre-
quency line.
"File: Trace A" Trace A is loaded from a file. The file name is entered in the subse-
quent parameter field.
"File: Trace B" Trace B is loaded from a file. The file name is entered in the subse-
quent parameter field.
