Recorder Output

The rear panel Recorder Output connector produces a DC voltage that
corresponds to the power level in Watts of the channel, depending on the
measurement mode. This DC voltage ranges from 0 to +1 Vdc. The output
impedance is typically 1 kW . Channel and display offsets and duty cycle
have no effect on the Recorder Output.
For example, the Recorder Output can be used to;
• record swept measurements on an X- Y recorder
• level an output from a source using external leveling or
• monitor the output power on a strip chart recorder. A setup for
