If several SACCH reported values are needed from the same report, the first value needed should be queried
three times (to receive a stable new report). Then the additional values should be immediately queried using
the :LAST? query before the next report arrives or the measurement parameters are changed again.
The :LAST? query is not a hanging query; values are returned from the last SACCH report. As shown in the
following program example (line 60), the :LAST? command is optional. If :NEW? is not used in the
MS:REPORTED command, the :LAST value is automatically reported.
Program example:
10 OUTPUT 714;"CALL:CELL:POW -83"
20 OUTPUT 714;"CALL:MS:TADV 11"
30 OUTPUT 714;"CALL:MS:TXL 11"
40 OUTPUT 714;"CALL:MS:REPORTED:TXL:NEW?;NEW?;NEW?"
50 ENTER 714;Ignore_result,Ignore_result,Valid_result ! Only use Valid_result
60 OUTPUT 714;"CALL:MS:REPORTED:RXL?;TADV?"
70 ENTER 714;Rceived_lvl,Timing_adv
80 END

SACCH Report Measurement Results

• MS TX level reported results reflect the value set in the Call Parms, MS TX Level field.
• TCH timing advance reported results reflect the value set in the Call Parms, Timing Advance field.
• RX Level reported reflects the received level of TCH in dB, from the Call Parms, Cell Power field that the
MS measured during the preceding SACCH.
• RX Qual reported reflects the perceived quality of the signal used for the RX level SACCH report.

:NEW?
t0: measurement parameter is changed to a new value.
t1-t2: MS measures the new value.
t3: the test set receives the first SACCH report that
contains valid results reflecting the new parameter value.
