PvT Summary (TEDS)
is a summary of power vs. time information for the composite signal (all TEDS subcarriers) for elements of the slot (overall slot power and data and power off levels).
If the trace is blank and NO DATA appears in the upper-right corner or if the trace is blinking between a display and NO DATA, there is a problem with the VSA setup or the signal input. Check the slot format, channel bandwidth and modulation type in the TEDS Demodulation Properties dialog box.
The following are parameters for :
|
Parameter |
Description |
|---|---|
|
Ref Pwr |
Average power of all sync and pilot symbols. See Comp Error Summary. |
|
Slot Pwr |
Composite slot power in dBm deciBels referenced to a milliWatt: dB relative to 1 milliwatt dissipated in the nominal input impedance of the analyzer. Slot power is a measurement of the average RMS power over an entire slot. |
|
Rel Slot Pwr |
Slot power relative to the reference power (Ref Pwr). |
|
Burst Pwr |
Composite burst power in dBm. Burst power is a measurement of the average RMS power in the burst itself. |
|
Rel Burst Pwr |
Burst power relative to the reference power (Ref Pwr). |
|
Off Avg Pwr |
Composite power in dBm of the "power off" period. The off period includes the time before the ramp-up of the burst and after the ramp-down of the burst. See PvT Off Analysis Time for more information. |
|
Rel Off Avg Pwr |
Average power of the "power off" period relative to the reference power (Ref Pwr). See PvT Off Analysis Time for more information. |
|
Off Pk Pwr |
Peak power in dBm of the "power off" period. The off period includes the time before the ramp-up of the burst and after the ramp-down of the burst. See PvT Off Analysis Time for more information. |
|
Rel Off Pk Pwr |
Peak power of the "power off" period relative to reference power (Ref Pwr). See PvT Off Analysis Time for more information. |
|
Sym 0 Time |
Time from trigger to the first symbol, which is useful for slot alignment measurements. |
