Chapter 4 Input/Output
Sets the input/output interface.
Input Impedance
Sets the input impedance for voltage-to-power conversions (refer to equation (2-4)).
The default input impedance is 50 Ω. To measure a 75 Ω device, you should use a 75
Ω to 50 Ω adapter (option) supplied by RIGOL to connect the analyzer with the
system under test, and then set the input impedance to 75 Ω.
Ext Gain
Compensates for gain or loss in the measurement system outside the instrument.
Remarks:
⚫ The value does not affect the trace position, but will modify the parameters such
as reference level readout and the marker amplitude readout.
⚫ You can use the numeric keys, the knob, and the arrow keys on the front panel
to modify this parameter; also you can modify it on the touchscreen. For details,
refer to descriptions in "Parameter Setting".
