4.2 Spectrum Analyzer

CONFigure Commands

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 will not initiate the taking of a measurement.

Current instrument settings may be changed to default values. These changes will be identified with their respective measurement commands.

The CONFigure? query returns the name of the current measurement.

Configure Adjacent Channel Power Ratio

:CONFigure:ACPower

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

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.

Configure Field Strength

:CONFigure:FSTRength

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.

[:SENSe]:FSTRength:ANTenna

 

Configure Occupied Bandwidth

:CONFigure:OBWidth

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.

Configure Tracking Generator Measurement

:CONFigure:TGENerator ABSStats|RELStats

This command configures the selected tracking generator statistic measurement. It disables any other active one-button measurements, including channel power, occupied bandwidth, AM/FM demodulation and C/I.

Sets the tracking generator measurement state to ON.

Sets the instrument to single sweep mode (:INITiate:CONTinuous OFF).

Measurement settings can be modified by using the [:SENSe]:TGENerator commands before initiating a sweep.

When the ABSStats option is selected, the measurement results are equivalent to the results that are displayed by choosing Shift-4(Measure), then Tracking Generator, then Abs Max, Min, Avg from the front panel.

When the RELStats option is selected, the Normalize state is set to ON and the measurement results are equivalent to the results that are displayed by choosing Shift-4(Measure), then Tracking Generator, then S21 Insertion Loss, then S21 Max, Min, Avg from the front panel.
