Index Result Parameter
0 Overall Pass/Fail Result shows the mask test result (0.0 = pass, 1.0 = fail, -1.0:
Not tested)
1 Power of single burst is the mean power (in dBm) across the useful part of the
selected burst in the most recently acquired data, or in the last data acquired at
the end of a set of averages. If averaging is on, the power is for the last 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 average is off, the value of the 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 First error point is the time (in seconds) which indicates the point on the X-scale
where the first failure of a signal was detected. If the limit passes, this data has
no meaning.
