User-Defined Dynamic Range
This portion of the FFT tool (red box 4,
) is used to examine the SNR of a specific channel within
a given frequency band defined by the
Low Frequency
and
High Frequency
fields. The SNR displayed in
this window also appears under the
Dynamic Range
heading, as shown in
Figure 30. Changing the User-Defined Dynamic Range for Channel 1
5.3.5
Input Amplitude (V
PP
)
The
Input Amplitude
field (red box 5,
) is a user input that is important for accurately calculating
the CMRR of each channel.
5.3.6
Waveform Zoom
This zoom function allows a closer examination of the FFT at frequencies of interest, as shown in
Figure 31. FFT Plot Using Waveform Zoom Function
