VOLTage:UNIT {VPP|VRMS|DBM}
VOLTage:UNIT?
Select the units for output amplitude (does not affect offset voltage or
high/low levels). The default is VPP. The :UNIT? query returns "VPP",
"VRMS", or "DBM".
• The function generator uses the current units selection for both front
panel and remote interface operations. For example, if you select
"VRMS" from the remote interface using the VOLT:UNIT command,
the units are displayed as "VRMS" on the front panel.
• The VOLT? query command (see page 156) returns the output
amplitude in the units set by the most recent VOLT:UNIT command.
• The output units for amplitude cannot be set to dBm if the output
termination is currently set to "high impedance". The units are
automatically converted to Vpp. See the OUTP:LOAD command on
page 163 for more information.
• Unless you specify the units as part of the APPLy or VOLT command,
the VOLT:UNIT command takes precedence. For example, if you
select "Vrms" using the VOLT:UNIT command and do not include
units with the APPLy or VOLT command, the value specified for the
amplitude parameter in the APPLy command will be in "Vrms".
