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 192) 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 199 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”.
