Code Description
−20337 The specified time stamp occurs after the end of the limit.
−20335 Waveforms are not contiguous. You can concatenate two waveforms (A, B) with same dt only if they are contiguous, that is if t0_B = t0_A + N * dt, where N is the number of samples of waveform A.
−20334 Cannot align waveforms because their time stamps are separated by more than 10 times the duration of the longest waveform.
−20333 Cannot align two waveforms with same dt if their samples are not clocked in-phase. Alignment of two waveforms is possible only if the samples share the same dt and are in-phase, that is the difference between their t0s is a integer multiple of dt.
−20332 Internal error: The number of threads attribute is less than zero. If the problem persists, contact National Instruments technical support.
−20331 Internal error: The parameter struct pointer is Null, possibly because of changes to the calling VI block diagram. If the problem persists, contact National Instruments technical support.
−20330 Internal error: The result pointer is Null, possibly because of changes to the calling VI block diagram. If the problem persists, contact National Instruments technical support.
−20329 Internal error: The cursor struct pointer is Null, possibly because of a change to the calling VI block diagram. If the problem persists, contact National Instruments technical support.
