group is displayed.
Inc Redund Sets On or Off of the Incremental Redundancy of re-forwarding PDTCH during Test Mode: Ack test.
Averaging Displays the average value of Peak TX Power, Phase Error, and Frequency Error. Sets the averaging
number from 2 to 200, or Off. When this function is not required, select Off.
PWR CNTL Sets one of the factors defined for Power Control Levels according to the Radio System. The allowable
range is as follows:
GSM850, GSM900: 2 to 19 (+39dBm to +5dBm)

Selects measurement slot from 2 to 4 depending on the setting of the Slot Config.
Test Mode Selects from ACK, A, or B.
ACK: Measurement of Peak TX Power, Phase Error, Frequency Error, and BLER
A: Measurement of Peak TX Power, Phase Error, and Frequency Error
B: Measurement of Peak TX Power, Phase Error, Frequency Error and BER. Active in Unacknowledged
Mode for UL/DL.
* The changing magnification softkey is available. Refer to Storing Numeric Values on page 8 and Changing Magnification Softkey on
