Monitoring the Test Signal Level (AC)
The signal level actually applied to a DUT differs from the setting applied to
the signal source because some electrical loss occurs between each test
terminal and the DUT. The E4990A provides a feature that allows you to
monitor both the voltage and amperage values of the test signal level
actually applied to the DUT, whether you measure the signal source level
by voltage or current. This feature is called "test signal level monitor".

Monitoring the DC Bias Level
In most cases, the DC bias level actually applied to a DUT differs from the
setting applied to the dc bias source because some electrical loss occurs
between each test terminal and the DUT. The E4990A provides a feature
that allows you to monitor either the voltage or amperage value of the dc
bias actually applied to the DUT. This feature is called the "DC bias level
monitor."
Monitoring the Test Signal at Sweep Start
You can monitor the dc bias level (either voltage or amperage) at the
beginning sweep through the dc Voltage/Current Bias Monitor field, which
is located in the right-upper part of the screen LCD and labeled DCV, DCI.
This field is updated at each sweep.
