Recorder Output; Test Setup For Recording Swept Measurements - Agilent Technologies E4418B User Manual

Power Meter Operation

Recorder Output

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 kΩ . 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 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.
