Signaling Encoder and Decoder Screens

The Decoder’s Signal Source

The decoder always gets its signal immediately after the de-emphasis network of the AF analyzer. De-emphasis can be turned on or off on the AF ANALYZER screen, or can be controlled while using the decoder by assigning a global USER key to the De-Emphasisfield.

Decoder Frequency Measurements

The decoder uses a different timebase for frequency counting than the AF Analyzer. Therefore, their measurements may be different when measuring the same signal (by a very small amount).

The Encoder

The encoder’s uses AF Generator 2 to generate its signals. The available signaling formats are AMPS-TACS, NAMPS-NTACS, DTMF, and a function (waveform) generator.
