Making Measurements
Measuring Conversion loss
If necessary to view the measurement trace, press
Autoscale .
2. To interpret the conversion loss measurement, refer to Figure 3-15 or
your analyzer’s display if you are making this measurement on your
instrument.
a. The values shown on the horizontal axis represent the source RF
output. The values shown on the vertical axis are the power ratio in
decibels
of the transmitted signal through the device divided by
the incident power. To display the result in logarithmic magnitude
format (designated by Log Mag at the top of the measurement screen),
the analyzer computes the measurement trace using the following
formula:
Conversion Loss
=
10
log
where
= the power measured at the IF output of the mixer and
where
= the incident power at the RF input.
b. A level of 0
would indicate a perfect device (no loss or gain). Values
greater than 0
indicate that the mixer has gain. Values less than
0
indicate mixer conversion loss.
3. If you wish, you can quickly determine the mixer’s minimum conversion
loss by pressing
