Keysight N9010A EXA Service Guide
E The burst signal cannot be detected because of
inappropriate parameter settings or incorrect signal.
An in appropriate parameter setting could cause the signal
to be partially, rather than fully, on the display, Burst
Search Threshold and/or Burst Search Length may need to
be adjusted.
An incorrect signal could have either insufficient power, the
rising or falling edges cannot be detected, or the burst is
less than 126 microseconds.
Carrier signal is not actually bursted.
W-CDMA: Either the signal being analyzed has insufficient
power, the rising or falling edges cannot be detected, or
the burst is less than 126 microseconds.
W_CDMA: Cannot synchronize measurement with PRACH
channel for Power Control measurement, because the
signal cannot be found. Make sure PRACH is present in the
W-CDMA uplink signal, and that the preamble signature
and scramble code are set correctly.
GSM: Data was acquired but a GSM burst was not found,
with the timeslot mode disabled.
NADC, PDC: A valid burst is not found when the Device is
MS.
E 1xEV-DO: Data was acquired but a 1xEV burst was not
found, with the timeslot mode disabled.
Bluetooth: The burst that has been found does not
correspond to the currently selected Bluetooth packet type
(the burst length may be too short).
WLAN: The instrument cannot find a valid WLAN burst. You
may need to extend the search length.

E The pilot burst used for time reference is not active.
