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 PSA, this error was reported as one of the following
error numbers: 10872, 10962, 13070, 10228, 10768

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.

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.
