VNA Master™Programming Manual : Spectrum Analyzer Commands : :CONFigure Subsystem
 
:CONFigure Subsystem
This set of commands prepares the instrument for the selected measurement. It disables any currently‑enabled measurements and activates the specified measurement. It sets the instrument to single sweep mode, waiting for an :INITiate command. It does not initiate the taking of a measurement.
Current instrument settings may be changed to default values. These changes are identified with their respective measurement commands.
 
Configure Adjacent Channel Power Ratio
:CONFigure:ACPower
Description
Configures the default adjacent channel power ratio measurement. Disables any other active one‑button measurements, including channel power, occupied bandwidth, AM/FM demodulation and C/I. Sets the main channel bandwidth equal to the span. Sets the adjacent channel bandwidth and channel spacing equal to the main channel bandwidth. Sets the detection method to RMS. Sets the instrument to single sweep mode (:INITiate:CONTinuous OFF). Measurement settings can be modified by using the [:SENSe]:ACPower commands before initiating a sweep.

Configure Channel Power
:CONFigure:CHPower
Description
Configures the default channel power measurement. Disables any other active one‑button measurements, including ACPR, occupied bandwidth, AM/FM demodulation, and C/I. Sets the integration bandwidth equal to the span. Sets the detection method to RMS. Sets the instrument to single sweep mode (:INITiate:CONTinuous OFF). Measurement settings can be modified by using the [:SENSe]:CHPower commands before initiating a sweep. Note that this measurement is not valid in zero span.

Configure Field Strength
:CONFigure:FSTRength
Description
Configures the default field strength measurement. Disables any other active one‑button measurements, including channel power, adjacent channel power, occupied bandwidth, AM/FM demodulation, and C/I. Sets the antenna to the first antenna in the instrument’s antenna list. Sets the instrument to single sweep mode (:INITiate:CONTinuous OFF). Measurement settings can be modified by using the [:SENSe]:FSTRength commands before initiating a sweep. Note that this measurement is not valid in zero span.

Configure Occupied Bandwidth
:CONFigure:OBWidth
Description
Configures the default occupied bandwidth measurement. Disables any other active one‑button measurements, including channel power, ACPR, AM/FM demodulation, and C/I. Sets the method to %. Sets the % of power to 99 %. Sets the instrument to single sweep mode (:INITiate:CONTinuous OFF). Measurement settings can be modified by using the [:SENSe]:OBWidth commands before initiating a sweep. Note that this measurement is not valid in zero span.
