You can set the units for output amplitude to Vpp, Vrms, or dBm.
See “Output Units” on page 64 for more information.
•
For dc volts , the output level is actually controlled by setting the
offset voltage. You can set the dc voltage to any value between
±
5 Vdc
into 50 ohms or
±
10 Vdc into an open circuit. See “DC Offset Voltage”
on page 62 for more information.
To select
dc volts
from the front panel, press
Offset
and
hold it down
