Table 1: Allowed modulation waveforms for each modulation type

MODULATION RATE

Pressing [RATE] displays and sets the modulation rate. Use the keypad and

unit indicators of Hz, kHz, or MHz (or the MODIFY up/down keys) to set the

modulation rate.

The modulation rate is the frequency of the modulation waveform. For exam-

ple, if the modulation type is AM, the waveform a sine wave, and the rate

1 kHz the modulating waveform will be a 1 kHz sine wave. For sweeps the

modulation rate is the inverse of the sweep time (ie., a 10ms sweep would be

entered as 100 Hz). Burst modulation has no associated modulation rate and

the message "not applic" is displayed if [RATE] is pushed.

The modulation rate has a range of 0.001 Hz to 10 kHz for AM, FM, and PM.

The range for sweeps is 0.001 Hz to 1 kHz (1000s to 0.001s sweep time).

The modulation rate may be set with two digits of resolution. If the modulation

waveform is set to ARB (AM ARB, FM ARB, or PM ARB) the modulation rate

has a different meaning. See the ARBITRARY MODULATION section for

more details.
