Custom Setup Example

This example explains how to monitor several signals, plus a potential intermodulation product, to see if there is a correlation between the nearby signals and an intermittent interference problem.

The signals on or near the rooftop are:

•	An FM broadcast station at 106.5 MHz

•	A paging transmitter at 157.86 MHz

•	Three cellular sites:

•	US CDMA PCS channel 50 (1932.5 MHz)

•	AMP/EIA 553 channel 525 (885.750 MHz)

•	GSM 1800 channel 512 (1805.2 MHz)

•	A Ham repeater at 147.36 MHz

•	A Ham repeater at 446.5 MHz

•	A land mobile repeater at 451.7875 MHz

•	A public safety repeater at 485.5625 MHz

•	In addition, the site is near the flight path of an airport. The approach frequency is 121.4 MHz.

Set up a measurement channel for each of the signals to be observed plus extra channels for any intermodulation products to be observed.

After the channels are set up, press Shift | File | Save then press the Change Type submenu key and select Setup from the list by using either the Up/Down arrow keys or the rotary knob, then press Enter. Name the setup for easy recall later and press Enter.
