Figure 2-25 Group Delay Measurement Example
The displayed measurement trace shows the device under test delay, relative to the "calibration" mixer. This
measurement is also useful when the device under test has built-in filtering, which requires >30 dB range
(the maximum of R input). PORT 1 to PORT 2 range is >100 dB.
