Test Signal Level

The E4980A/AL's test signal level can be set as the effective value (RMS value)
of a sine wave of the test frequency from the unit's internal oscillator. You can
set either the oscillator voltage level or the oscillator current level. The output
impedance is 100 .
The set value of the oscillator current level is the value set when the
measurement contacts (UNKNOWN terminals) are shorted together.
The set value of the oscillator voltage level is the value set when the
measurement contacts (UNKNOWN terminals) are opened.
The E4980A/AL can measure a device using a constant voltage or current level
by using the automatic level control function. (The automatic level control
function (ALC field) can be set to ON from the MEAS SETUP page.) When a
constant voltage or current level measurement is performed, an asterisk mark
(*) appears at the end of the LEVEL display. For more information about the
automatic level control function, refer to
Test signal level and resolution (Standard)
When option 001 (power/DC bias enhance) is not installed, the oscillator
voltage level can be set with a resolution listed in
current level can be set with a resolution listed in
