Making Measurements
Measuring Transmission Response
1. To view the entire measurement trace on the display, press
2. To interpret the transmission measurement, refer to Figure 3-6 or
your analyzer’s display if you are making this measurement on your
instrument.
a. The values shown on the horizontal axis are the frequencies in MHz.
The values shown on the vertical axis are the power ratios 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:
Transmission
=
10
log
where
= the power transmitted through the device and
where
= the incident power.
b. A level of 0
would indicate a perfect through cable or device (no
loss or gain). Values greater than 0
indicate that the DUT has gain.
Values less than 0
indicate loss.
3. To quickly determine the filter’s minimum insertion loss, press
Marker
Search Mkr
Max.
3-22
4. Note the marker readout in Figure 3-6 provides the frequency and
amplitude of the minimum insertion loss point.
