Boonton Radio Corp 202-G FM-AM Signal Generator

On one of my visits with Alan Douglas, he insisted that I take this Boonton 202-G signal generator as a condition for getting some other item that I wanted from him.

The 202-G is a bit of an odd duck. It's a variant of the Boonton 202-F, which itself is a variant of the 202-E. The 202-E was the general-purpose version of the signal generator, covering 54 to 216 Mc. The 202-F  was a modification of the 202-E designed to handle the 175 to 250 Mc. telemetry band. Similarly, the earlier 202-D was the telemetry-band variant of the general-purpose 202-C.

This chart shows the evolution of Boonton Radio Corp signal generators up to the 202-E and 202-F. It is taken from the BRC journal The Notebook, Number 18, Summer, 1958.

In 1959, Boonton introduced the 202-G to cover the full range of the recently-extended telemetry band (215 to 260 Mc.)

In addition to extending the frequency coverage, Boonton added internal modulation frequencies covering the center frequency of some of the IRIG baseband FM channels. See Table 3-1A of the IRIG Telemetry Standard RCC Document 106-09, Chapter 3, April 2009.
