Recorder Output; Test Setup For Recording Swept Measurements - HP E4419B User Manual

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 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
recording swept measurements is shown in Figure 2-20.
See Figure 2-22 for details on which power meter functions are
implemented in the recorder output.
