STEP 4. Analyzing Measurement Results
This section describes how to use the marker function to read out important parameters for
the transmission measurement of the bandpassfilter (insertion loss, -3 dB bandwidth).
Measuring the Insertion Loss
Step 1. Display a marker.
•
[Marker] - Marker 1
Step 2. Using one of the following methods, move the marker to the center frequency of the
bandpass filter.
• On the entry bar, press
[9] [4] [7] [.] [5] [M/μ].
• Turn the rotary knob ( ) on the front panel to set it to the center frequency (947.5
MHz).
Step 3. Read the marker value displayed as shown in Figure 3-17. In this example, the response
value denotes the insertion loss.
