217 7 Demod Error E This error is normally generated because of
one of the following reasons:
1. There is no carrier signal.
2. Walsh channels other than the pilot are
active.
3. There is some other modulation problem
that will prevent the measurement from being
made.
This problem must be corrected before the
measurement can continue.
cdma 2000 & W-CDMA: Cannot correlate to
the input signal and no active channel is found.
(from composite EVM measurement) An active
channel must meet the default threshold
criteria that it is within 20 dB of the highest
power code channel. The threshold can be
changed using the active set threshold
function in the Meas Setup menu.
cdmaOne: A correlation failure with the pilot
CDMA channel occurred during synchronous
demodulation.
1xEV-DO: Cannot correlate to the input signal
and no active channel is found. (from
composite EVM measurement) An active
channel must meet the default threshold
criteria that it is within 20 dB of the highest
power code channel. The threshold can be
changed using the active set threshold
function in the Meas Setup menu.
In the PSA, this error was reported as one of
the following error numbers: 10872, 10962,
13070, 10228, 10768
217 7 Demod Error;Can’t
correlate
E Cannot correlate to the input signal and no
active channel is found. (from composite EVM
measurement) An active channel must meet
the default threshold criteria that it is within 20
dB of the highest power code channel. The
threshold can be changed using the active set
threshold function in the Meas Setup menu.
217 7 Demod Error;Data
interval too short
E There are not enough input I/Q pairs for the
measurement calculation. This may be caused
by an incorrect data capture.
217 7 Demod Error;No
active channel
E There is no active channel detected.
