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 type. This DC voltage ranges from 0 to +1 Vdc. The output
impedance is typically 1 k
Ω
, while 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
•
Level an output from a source using external leveling, or
•
Monitor the output power
To access the
Recorder
menu, press
, and enable
Rec
. This allows
you to switch the recorder output signal on or off, or to enable or disable
autoscaling of the signal. The
Max Power
and
Min Power
value fields allow
you to scale the power levels to represent the 1 Vdc maximum and 0 Vdc
minimum output voltages of the recorder output.
