“Optimizing Synthesizer Performance” in Chapter 1.

(Opt ion 002 only) Outputs the 

generated AM or FM waveform. This output can drive 

 or

greater. The AM output is scaled the same as it is generated, either

 or 10 

 The FM scaling depends on the FM deviation

chosen. The following table shows the scale versus deviation.

There are two AM operation modes: linear and log.

When the synthesizer is in linear AM mode, the input accepts a

-1 to 

 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 

 input, the RF output is 100% (3 

 higher that the

reference level. Therefore, there must be 

 

 of margin between

the reference power level and the maximum available at a given
frequency. The on (OV input) to off 

 input) ratio is a function

of power level and frequency, but is always greater than 20 
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
