View/Display
Metrics window
Name Corresponding Results Resolution
Number of slots n=1 1st element
Number of slots found in the captured data. (In case of PRACH
Power measurement, it always returns 0.)
nnn
Slot (1) If Meas Method is Waveform, it counts up from 1 to the
number of slots.
(2) If Meas Method is Chip Power, there are two ways to show
the slot number:
- If the Slot Number menu key on the Display menu is Rel, the
result counts up from 1 to the number of slots.
- If the Slot Number menu key on Display menu is Abs, the result
shows the absolute slot number determined by the scrambling
code.
In case (1), no corresponding information is returned via SCPI.
In case (2), the first slot number is always returned via SCPI (n=1
4th element).
nnn:
Result n=3
Averaged absolute power level of each slot, which is also
displayed as a light blue trace in RF Envelope window.
nn.nn dBm
Delta Adj Pwr n=5
Relative power level to the previous slot
nn.nn dB
Rel Pwr n=6
Relative power level to the first slot
nn.nn dB
PRACH Power Measurement
There are two windows, the "RF Envelope window" on page 2865 (upper) and the "Metrics window" on
page 2865 (lower).
