10-4 :FETCh Subsystem Chapter 10 — GSM Commands
10-6 PN: 10580-00341 Rev. C MS2720T PM
10-4 :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?
Title: Fetch Demodulator
Description: Returns the most recent Demodulator measurement results. The
Demodulator measurement must be the active measurement. The
current measurement can be queried using CONFigure?. Use the
CONFigure:DEMod command to set Demodulator as the active
measurement.
Data is returned as 9 comma-delimited values: Phase Error (rms),
Phase Error (peak), EVM (rms) in %, EVM (peak) in %, Origin Offset
in dB, C/I in dB, Magnitude Error (rms) in %, Modulation Type, and
TSC. “--” is returned for data that is not valid at that instance.
Related Command: MEASure:DEMod?
CONFigure:DEMod
READ:DEMod?
: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 to set
Pass/Fail as the active measurement.
