Mixer Measurement Example

Mixer Measurement Example

The program included in Example 8A is one of several mixer measurements discussed in
your analyzer’s user’s guide.

NOTE

This example program is for use on any 8753ET/ES analyzer and on 8720E
series analyzers with Option 089.

Example 8A: Comparison of Two Mixers — Group Delay, Amplitude
or Phase

Using this program, you can measure how two mixers compare in terms of group delay,
amplitude or phase. Refer to

Figure 7-2

.
