Programming the Phase Discontinuity Measurement

Programming the Phase Discontinuity Measurement

Last updated: January 16, 2009

This section provides an example of how to make phase discontinuity measurements via GPIB.

The basic procedure to perform phase discontinuity measurements is as follows:

  1. Establish an RB test mode connection between the UE and test set (see Step 4: Make a Connection ).
  2. Set UL CL Power Control Mode to Active Bits ( CALL[:CELL]:CLPControl:UPLink:MODE ).
  3. Set UE Target Power to the appropriate level ( CALL:MS:POWer:TARGet[: AMPLitude]? ).
  4. Set up the measurement using the SETup:WPDiscon commands.
  5. INITiate the measurement using the INITiate command.
  6. FETCh the measurement results using the FETCh:WPDiscon commands (or use the READ:WPDiscon[:ALL]? command to both initiate and fetch the measurement as a sequential operation).

90 OUTPUT Testset;"CALL:CLPControl:UPLink:MODE ACTive"
100 ! Set UL CL Power Ctrl Mode to Active Bits.
110 OUTPUT Testset;"CALL:MS:POWer:TARGet 21"
120 ! Set MS Target Power to +21 dBm.
130 !
140 ! *** Set Up Measurement Parameters ***

160 OUTPUT Testset;"SETup:WPDiscon:PCPattern DN5_4UP"
170 ! Set Power Control Pattern to 5DOWN/4UP.
180 OUTPUT Testset;"SETup:WPDiscon:NPRepetition 10"
190 ! Set the Number of Pattern Repetitions to 10.

210 ! *** INITiate and FETCh Measurements ***
220 !
230 OUTPUT Testset;"INITiate:WPDiscon"
240 ! Initiate a Phase Discontinuity measurement.

260 ! Fetch Phase Discontinuity measurement results.
270 ENTER Testset;Int,Num_slts,Wc_pd_slt,Wc_pd,Wc_evm_slt,Wc_evm
280 ! Retrieve the results.
