OPTIONAL FEATURES
RACK MOUNTING, -R5 OPTION
A rack mounting kit is available. The -R5 rack mount kit may be installed after first
removing the one Phillips screw on the side panel adjacent to the front handle.
DC OFFSET, -OS OPTION
A DC offset can be added to the output signal by applying a DC voltage to the rear-panel
OS connector. Internally, it is connected to the output centre conductor via a high quality
RF inductor. Do not exceed ±50V, 250 mA.
MONITOR OUTPUT, -M OPTION
The monitor output provides an attenuated replica (20 dB down) of the voltage on the
main output. The monitor output is designed to operate into a 50 Ohm load.
ELECTRONIC AMPLITUDE CONTROL, -EA OPTION
The output amplitude can be set to track the voltage on this input. Zero Volts in
corresponds to zero amplitude output, and +10V in corresponds to maximum amplitude
out. This mode is activated by selecting "Ext Control" on the front-panel amplitude menu,
or with the "source:voltage external" command.
