Synthesized Generator

The synthesized generator has low phase noise

and 1 Hz frequency resolution.

VCOs are used for frequencies above 3 GHz and

an integrated RF synthesizer for the 10 MHz to

3 GHz range. Internal filtering results in excellent

harmonic performance of <-55 dBc.

Optional step attenuators are available to set low

output powers for amplifier or receiver testing.

In CW mode the generator can be used for local

oscillator substitution. A power sweep is provided

for amplifier gain compression testing. External

FM can be applied by connecting an AF source to

the rear panel. With the FM option, an internal

generator provides frequency modulation of the

source.

When used with a scalar analyzer the generator

provides a swept synthesized output for frequency

characterization of components and systems.

List Mode

Frequency list mode provides up to 1024 frequencies that can be

entered into a list and output on receipt of a trigger command. The

trigger modes comprise: internal continuous, internal single step,

RS-232 control lines and external. The trigger sources can be from

either: menu softkey, GPIB or RS-232 command (GET or *TRG) or

a TTL trigger if the optional trigger board is fitted.

List mode can be enabled in either forward or reverse direction

through the frequency list.

Several lists can be stored as instrument settings to internal memo-

ry or floppy disks.

By using a 6230A or L series detector it is possible to carry out level

calibration.
