worst burst.
2 Power averaged is the power (in dBm) of N averaged analysis step intervals, if averaging is on. The power is
averaged across the useful part of the analysis step interval. Average m is a single timeslot from the acquisition. If
there are multiple timeslots in the analysis step interval, only one timeslot is used for average m. This means that N
analysis steps are acquired to make the complete average. If averaging is off, the value of power averaged is the
same as the power single burst value.
3 Start is the index of the data point at the start of the useful part of the burst
4 Stop is the index of the data point at the end of the useful part of the burst
5 T0 is the index of the data point where t0 occurred
6 Burst width is the width of the burst measured at 3 dB below the mean power in the useful part of the burst.
7 Maximum value is the maximum value of the most recently acquired data (in dBm).
8 Minimum value is the minimum value of the most recently acquired data (in dBm).
9 Burst search threshold is the value (in dBm) of the threshold where a valid burst is identified, after the data has been
acquired.
10 1st Error point is the time (in second) which indicates the point on the X Scale where the first failure of a signal was
detected. If the limit passes, returned data has no meaning.
11 Detected TSC is the most recently detected TSC. The returned value is 0~7 (Burst Type : Normal/Higher Symbol
Rate (HSR)) if TSC detected. If TSC not detected, the returned value is –999.0. If Amptd or NONE (Power vs Time
only) specified in Sync Type, the returned value is –999.0. In multi slot condition, the returned value is the detected
TSC of the specified slot(Time Slot ON) or the first evaluated slot(Time Slot OFF).
Note: The returned value in Sync (Synchronization Burst) is.

12 Detected Mod scheme is the most recently detected modulation scheme. The returned value is as follows.
0 for GMSK, 1 for Normal Burst (NB) 8PSK, 2 for NB 16QAM, 3 for NB 32QAM, 11 for Higher symbol rate Burst
(HB) QPSK, 12 for HB 16QAM, 13 for HB 32QAM
13 Estimated Carrier Power (ECP) in dBm
14 Time Offset Power Results in dB
If averaged number N = 1, the power measured and calculated at Offset Times relative to the mean power across
the useful part of the burst
If averaged number N > 1, Time Offset Results return the limit margin worst case results. That is, 12 time offset
results of the burst which has the worst limit margin are returned
12 Time Offsets can be set by SCPI commands, please see PVT Time Offsets for details
