The TR501 is a two-wide unit compatible with the Tek TM500-Series Power Modular. Sweep rates are controlled with the Spectrum Analyzer and the output level is controlled from the Tracking Generator.
For later expansion of the system, a TM503 Mainframe is recommended which allows for the addition of a DC-Series Frequency Counter Module for direct measurement of the center frequency. When used as a CW source, the TR501/7L12 system has a 200 Hz stability increasing overall system dynamic range to over 100 dB. Allows swept frequency tests from 100 kHz to 1.8 GHz to be made with a 7L12 Analyzer.
