Making Measurements
Using Bandwidth Limits to Test a Bandpass Filter
Figure 1-77 Bandwidth Markers Placed 40 dB Below the Bandpass Peak
Displaying the Bandwidth Value
1. Display the bandwidth value by pressing the softkey until ON is displayed on
the softkey.
When this softkey is set to the ON position, the measured bandwidth value is displayed in the upper left
corner of the display, to the right of the bandwidth Pass/Wide/Narrow message. This value changes as
the analyzer continues measuring the bandwidth. The bandwidth value is displayed in
Figure 1-78.
If the filter is failing the bandwidth test, the color of the bandwidth value is red, the same color as the
failure (Wide) message of
Figure 1-76. If the filter is passing the bandwidth test, the displayed bandwidth
value is green (the same color as the bandwidth test Pass message).
