AM/FM OUTPUT (Opt ion 002 only) Outputs the internally- generated AM or FM waveform. This output can drive 500 or greater. The AM output is scaled the same as it is generated, either 100%/V or 10 dB/V. The FM scaling depends on the FM deviation chosen. The following table shows the scale versus deviation.

AM INPUT There are two AM operation modes: linear and log.

When the synthesizer is in linear AM mode, the input accepts a -1 to +lV signal. With an AM input of OV, the RF output level (the reference level) is unaffected; at -lV input, the RF is shut off, and with a +lV input, the RF output is 100% (3 dB) higher that the reference level. Therefore, there must be 23 dB of margin between the reference power level and the maximum available at a given frequency. The on (OV input) to off (-1V input) ratio is a function of power level and frequency, but is always greater than 20 dB.

The amplitude of the RF output changes linearly as the AM input changes.

When the synthesizer is in log AM mode, the input accepts a wider range of input signal. For every -lV input, the RF output level
