Condition Errors 201 to 299, Signal Integrity
217 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.
217 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 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 Demod Error;Muxed
bits not found
E Multiplexed Data Demod Bits are not generated even
though Data channel is selected, because all 16 data
code channels are not active
217 Demod Error;No
active channel
E There is no active channel detected.
217 Demod Error;No full
subframe found
E No sub-frame or only part of one sub-frame is detected.
217 Demod Error;Not an
active slot
E There is no active slot detected.
