Recorder Output
The rear panel Recorder Output connectors (1 and 2) produce a dc voltage that
corresponds to the power level in Watts of the selected measurement window.
This dc voltage ranges from 0 to +1 Vdc. The output impedance is typically 1 kΩ.
For example, the Recorder Outputs can be used to:
– Record swept measurements
– Level an output from a source using external leveling, or
– Monitor the output power
To access the Recorder menu press
to switch the Recorder Output signal on or off and set the scaling of power levels
automatically or manually. The
manually scale the power levels to represent the 1 Vdc maximum and 0 Vdc
minimum output voltage of the Recorder Output. Otherwise, you can set the
Recorder Output to Auto to enable auto-scaling.
In auto-scaling, the minimum power is fixed at –150 dBm and the maximum
power is automatically scaled based on the current power level. The auto-scaled
maximum power ranges from –140 dBm, steps every 10 dBm until +230 dBm
depending on the current power level. The auto-scaling is not applicable if the
measurement of the selected window is a difference, ratio, channel C, or D
measurement.
Procedure
Set the recorder output as follows:
Ensure you have selected the channel you want to set up.
