Keys
To Set A Measurement Reference Point. Use the :REFerence:VALue commands to
set a measurement reference point.
Syntax
:REFerence:VALue <real number>
Example
OUTPUT 714;"MEAS:RFR:POW:REF:VAL 20"
This sets the measurement reference point for the TX power measurement to
20 watts.
NOTE: When setting a measurement reference point, any non–attribute unit’s unit-of-measure must
be specified in the command string, otherwise the current attribute unit is assumed by the Test
Set. Refer to “To Specify Units-of-Measure for GPIB Data Transfer” in
the Operating
Overview chapter of the E8285A User’s Guide.
To Query A Measurement Reference Point.
Use the :REFerence:VALue?
commands to query a measurement reference point.
Syntax
:REFerence:VALue?
Example
OUTPUT 714;"MEAS:RFR:POW:REF:VAL?"
ENTER 714;Ref_val
This queries the measurement reference point for the TX power measurement.
NOTE: When querying a measurement reference point through GPIB, the Test Set always returns
numeric values in attribute units, regardless of the current display units or GPIB units settings.
Numeric values are expressed in scientific notation.
