17 Total power over a slot (Average) is a floating point number (in dBm) of the

total RF power over a measurement slot.

18 First Slot Number is an integer number of the first slot in Capture Interval. This

is not averaged even if the averaging function is On. It is always the last cycle of

the measurement.

19 DPCCH Slot Format: (floating) If Sync Type is DPCCH, the DPCCH slot

format value used for synchronization is returned.

0.0: Slot Format 0

1.0: Slot Format 1

2.0: Slot Format 2

3.0: Slot Format 3

4.0: Slot Format 4

5.0: Slot Format 5

If Sync Type is PRACH, the value returned is -999.0.

In BTS mode, the value returned is -999.0.

20 Preamble Signature: (floating)

BTS mode:

The returned value is always -999.0.

MS mode:

In Preamble Signature auto-detection mode, the detected signature code number

(from 0.0 to 15.0) is returned when the Sync Type is PRACH Message.

In Preamble Signature manual setting mode, the retuned value is the same as the

parameter setting. When the Sync Type is not PRACH Message, the returned

value is NAN.

21 Average Peak EVM (Average Peak) is a floating point number (in percent) of

the averaging for Peak EVM readings on each slot over the entire measurement

area.
