ADS130E08 ANALYSIS TOOLS
5.3.4 User-Defined Dynamic Range
This portion of the FFT tool (red box 4, Figure 27) 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.

5.3.5 Input Amplitude (V_PP)
The Input Amplitude field (red box 5, Figure 27) 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.
