Recorder Outputs
The rear panel Recorder Output connectors (A and B) produce 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 kΩ . Channel and display offsets, and duty cycle have no effect on the Recorder Outputs.
For example, the Recorder Outputs can be used to;
•record swept measurements on an
•level an output from a source using external leveling, or
•monitor the output power on a strip chart recorder. A setup for recording swept measurements is shown in Figure
