AM/FM OUTPUT
(Option 002 only) Outputs the internally-
generated AM or FM waveform. This output can drive50 
or greater. When driving 100  or less, a selftest error ma
ybe
generated. 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 op eration mo des: linear and log.
When the swept signal generator is in linear AM mo de, the input
accepts a
0
1 to +1 V signal. With an AM input of 0 V, the RF
output level (the reference level) is unaected; at
0
1 V input, the RF
is shut o, and with a +1 V input, the RF output is 100% (3 dB)
higher that the reference level. Therefore, there must b e

3dBof
margin between the reference p ower level and the maximum available
at a given frequency. The on (0 V input) to o (
0
1 V input) ratio is
a function of power level and frequency, but is always greater than
20 dB. The amplitude of the RF output c
hanges linearly as the AM
input changes.
