GENERAL INFORMATION
1-9
Modulation ALC:
Levels the applied external modulation over the range 0.75 to 1.25 V
RMS. High and low indicators in display indicate when the input is
outside leveling range.
Sweep mode
Any or all of the sources may be set to a carrier frequency sweep mode.
The sweeps are defined by entry of the start, stop and step frequencies.
A common step time can be set from 50 ms to 10 s per step. A
common trigger input at a rear-panel BNC connector may be used to
trigger a step or a complete sweep. Sweep can also be set to
continuous.
Frequency standard
The carrier frequency and internal modulation frequency are
synthesized from either an internal reference oscillator or an external
reference.
Internal standard:
10 MHz OCXO.

External input:
Requires an input of 220 mV RMS to 1.8 V RMS into 1 k

on rear-panel
BNC connector. Input frequency can be 1 MHz or 10 MHz.
External output:
Rear-panel BNC socket provides an output of 10 MHz at a nominal level
of 2 V pk-pk into 50
Ω.
Remote control
