VOLTage:LOW? [MINimum
︱
MAXimum]
Query the low voltage level.
VOLTage: RANGe:AUTO{OFF
︱
ON
︱
ONCE}
Disable or enable the voltage auto-ranging. The default is “On” where the
waveform generator selects an optimal setting for the output amplifier and
attenuators. When the auto-ranging is “Off”, the current setting is used.
z
The “ONCE” parameter enables the auto-ranging, selects an optimal
setting and then disables it.
z
The APPLY command overrides this command and turns the auto-ranging
on.
z
Disabling the auto-ranging can avoid momentary disruption caused by
attenuators switching while changing amplitudes. However, the amplitude
and offset accuracy may be adversely affected when reducing the
amplitude below the expected range change.
VOLTage: RANGe:AUTO?
“0” (off) or “1” (on) indicating the auto-ranging enable state is returned.
VOLTage:UNIT {VPP
︱
VRMS
︱
DBM}
Select the unit of the output amplitude. The default is VPP. The waveform
generator used the same unit for front panel and the remote interface, so the
front panel display in the unit that you select from remote interface.
If you don’t specify the unit in the APPLy or VOLT commands, the function
generation uses the unit specified in this command.
When the output termination is set to “high impedance”, you cannot specify the
output amplitude in dBm. The unit will be automatically converted to Vpp.
VOLTage:UNIT?
Query the unit of the output amplitude. “VPP”, “VRMS” or “DBM” will be
returned.
