3.3 Channel Power Measurement
Unit Example Notes
dBm :UNIT:POW
DBM
dB relative to one milliwatt
dBmV :UNIT:POW
DBMV
dB relative to one millivolt
dBmA :UNIT:POW
DBMA
dB relative to one milliamp
W :UNIT:POW W Watts
V :UNIT:POW V Volts
A :UNIT:POW A Amperes
dBmV :UNIT:POW
DBUV
dB relative to one microvolt
dBmA :UNIT:POW
DBUA
dB relative to one microamp
The unit dBuA can also appear as a "Transducer Unit" on page 566
When querying the Y-Axis unit, you can query the Transducer Unit to distinguish
between regular dBuA and the dBuA transducer unit. If :CORR:CSET:ANT?
returns NOC (for No Conversion), you are using a normal Y Axis dBuA. If it returns
UA, you are using a Transducer Unit dBuA
dBpW :UNIT:POW
DBPW
dB relative to one picowatt
dBmV/m
(Transducer
Unit)
:UNIT:POW
DBUVM
Sets the amplitude unit for the selected amplitude scale (log/lin) to dBmV/meter.
This selection is only available if a Correction is turned on, and the Transducer Unit
for that Correction is not None
See "Transducer Unit" on page 566
dBmA/m
(Transducer
Unit)
:UNIT:POW
DBUAM
Sets the amplitude unit for the selected amplitude scale (log/lin) to dBmA/meter.
This selection is only available if a Correction is turned on, and the Transducer Unit
for that Correction is not None
See "Transducer Unit" on page 566
dBpT
(Transducer
Unit)
:UNIT:POW
DBPT
Sets the amplitude unit for the selected amplitude scale (log/lin) to dBpT (dB
relative to one picotesla). This selection is only available if a Correction is turned on,
and the Transducer Unit for that Correction is not None
See "Transducer Unit" on page 566
dBG
(Transducer
Unit)
:UNIT:POW
DBG
Sets the amplitude unit for the selected amplitude scale (log/lin) to dBG (dB relative
to one Gauss). This selection is only available if a Correction is turned on, and the
Transducer Unit for that Correction is not None
See "Transducer Unit" on page 566
dBmA
(Transducer
Unit)
:UNIT:POW
DBUA
Sets the amplitude unit for the selected amplitude scale (log/lin) to dBmA. This
selection is only available as a Transducer Unit if a Correction is turned on, and the
Transducer Unit for that Correction is not None
See "Transducer Unit" on page 566
The unit dBuA can also appear as a normal Y Axis Unit (see above)
