Spectrum Master Programming Manual : CDMA Commands : :FETCh Subsystem
 
:FETCh Subsystem
This set of commands returns the most recent measurement data of the active measurement. They will not switch to another measurement.
To make a new measurement, use the INITiate command. To get new measurement data, use the READ or MEASure query commands.
:FETCh:DEMod:CDPower?
Title
Fetch Demodulated Channel Power
Description
Returns the most recent Code Domain Power measurement results.
Data is returned as 12 comma‑delimited values: Pilot Power in the current user set unit (dBm/W/mW), Channel Power in the current user set unit (dBm/W/mW), Noise Floor in dB, Rho, Carrier Feed Through in dB, Tau in ps, RMS Phase Error in deg, Frequency Error in Hz, Frequency Error PPM, Page in dBm, Sync in dBm, and Q Page. All invalid values are replaced with “--”.

:FETCh:OTA:MPATh?
Title
Fetch OTA Multipath
Description
Returns the most recent Multipath measurement results.
Data is returned as 14 comma‑delimited values: six Ec/Io Values in dB, six Tau values in ps, Channel Power in the current user set unit (dBm/W/mW), and Multipath Power in dB. All invalid values are replaced with “--”.

:FETCh:PFail?
Title
Fetch PASS/FAIL
Description
Returns the most recent PASS/FAIL measurement results. Measurement results are returned in a block of ASCII text in the format of <header><block>. The ASCII header specifies the number of data bytes. It looks like #AX, where A is the number of digits in X and X is the number of bytes in the <block>. The block consists of a set of records which indicate individual test results. Records are comma‑separated. Each record follows the format <test ID>: <input1> <input2> <min> <max> <value1> <value2> <PASS/FAIL/OPTION NOT INSTALLED>. The <test ID> field indicates which test was performed to retrieve these results. The < input1> and < input2> fields indicate the test setup. The <min> and <max> fields indicate the minimum and maximum values against which <value1> and <value2> were compared to arrive at the final PASS/FAIL result. If the specified test is not available in the instrument, the <PASS/FAIL> field will indicate “option not available” instead of “pass” or “fail”. All unused fields for a given test are represented by a double dash (“--”). To receive valid measurements, the Pass/Fail measurement must be the active. The current measurement can be queried using CONFigure?. Use the :CONFigure PFail command to set Pass/Fail as the active measurement.

Title
Fetch Adjacent Channel Power Ratio
Description
Returns the most recent Adjacent Channel Power Ratio measurement results.
Data is returned as 9 comma‑delimited values: The Absolute Adjacent Channel  1 Power, Absolute Adjacent Channel  2 Power, Absolute Main Channel  1 Power, Absolute Main Channel  2 Power, Absolute Main Channel  3 Power, Absolute Main Channel  4 Power, Absolute Main Channel  5 Power, Absolute Adjacent Channel  3 Power, Absolute Adjacent Channel  4 Power. All values are returned in dBm. Note that the values for all five main channel carriers are shown even if the number of carriers set on the instrument is below five.

:FETCh:RF:EMISsion?
Title
Fetch RF Spurious Emission
Description
Returns the most recent Spurious Emission measurement result. Data is returned as 5 comma‑delimited values for each marker/boundary (40 values total): Marker Amplitude in dB, Marker Frequency in Hz, RBW in Hz, Pass/Fail, and Mask Boundary Frequency in Hz. Markers that are not on will return “--” for Marker Amplitude, Marker Frequency, RBW, and Pass/Fail. All Mask Boundary Frequencies will show normally.
