INITIAL CONNECTIONS AND ADJUSTMENTS

Other connections to the ME-525A/USM are given below with the type of connector required at the ME-525AIUSM.

Connector (or connections) required at the unit (signal source) under test will not be the same for all applications.

RF IN

The RF IN connector is a type N connector. Input impedance is 50 ohms nominal.

The maximum

amplitude (rms) to be applied to the RF IN input is 7.0 volts (1.0 watt).

IF OUT

The IF output is available at the front panel IF OUT connector (type BNC). The level is approximately 0

dBm, and the nominal source impedance is 50 ohms.

AF OUT

The recovered audio signal is available at the front panel AF OUT connector (type BNC). The level is 1

volt rms at 1000 counts on the digital panel meter display, and the source impedance is 600 ohms.
