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
This option adds a bias tee circuit on the output, with a rear-panel “OS” connector. This
connector allows an externally generated DC offset to be added to the output. The desired
DC offset is applied to this connector, which is connected to the output centre conductor
through a high-quality RF inductor. Do not exceed ±50V, 250 mA.
DC OFFSET, "-OT" OPTION
This option adds a bias tee circuit on the output, and adds an internal 0 to ±5V DC bias
source. The offset level can be set by the front-panel controls, or by computer commands.
The internal DC source is active by default, unless the “volt:low ext” command is sent, or
the external mode is selected from the front panel offset menu. In that case, the user must
add the desired externally-generated DC offset to the rear-panel solder terminals (± 50
Volts / 250 mA maximum).
