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.
