Power Sweep

In this mode, the CPU has the ALC step the RF out-

put through a range of levels specified by the user.

This feature can be used in conjunction with the

sweep mode to produce a set of identical frequency

sweeps, each with a different RF power output level.

Amplitude Modulation

Amplitude modulation (AM) of the RF output signal

is accomplished by summing an external or internal

modulating signal into the ALC loop. External

modulating signals come from the front panel or

rear panel AM IN inputs; the internal modulating

signal comes from the A8 Function Generator PCB.

The AM Input Sensitivity DAC and the AM Calibra-

tion DAC, under the control of the CPU, adjust the

modulating signal for the proper amount of AM in

both the linear (log amp in) and the log (log amp by-

passed) modes of operation. The adjusted modulat-

ing signal is summed with the level reference, slope,

and detector inputs into the ALC loop. This pro-

duces an ALC control signal that varies with the

modulating signal. The action of the ALC loop then

causes the envelope of the RF output signal to track

the modulation signal.

Pulse Modulation Operation

During pulse modulation, the ALC level amplifier

(A10 ALC PCB) is operated as a sample/hold ampli-

fier.The level amplifier is synchronized with the

modulating pulses from the A6 Pulse Generator

PCB so that the ALC loop effectively operates only

during the ON portion of the pulsed modulated RF

output.

Pulse

Generator

Operation

The A6 Pulse Generator PCB provides the internal

pulse generating function for the 682XXB/683XXB.

It also interfaces external pulse inputs from the

front or rear panel connectors to the pulse modula-

tor driver in the external mode.

The pulse generator produces a pulse modulation

waveform consisting of single, doublet, triplet, or

quadruplet pulse trains at variable pulse rates,

widths, and delays. It operates at two selectable

clock rates—10 MHz and 40 MHz. In addition, the

pulse generator produces a sync pulse and video

pulse output that goes to the rear panel and a sam-

ple/hold signal that goes to the A10 ALC PCB. The

sync pulse output is for synchronizing auxiliary in-
