| 8043 | Delays must be a multiple of {0} samples | Ensure the pulse duration parameter is valid. |
| 8044 | Number of samples is less than the minimum pulse duration of {0} samples | Verify that the duration of all pulses meets or exceeds the minimum pulse duration. If necessary and possible, you may consider zero-padding the start/end of very short pulses such that they meet or exceed the minimum duration. |
| 8045 | A buffer overflow occurred during result collection. | Reduce the number of shots or measurements, or increase the rep_delay |
| 8047 | A pulse scheduling conflict occurred. | Increase the lengths of any short pulses, and/or insert more delay between them. |
| 8048 | A pulse or combination of simultaneous pulses exceeded the available DAC amplitude range. | Reduce the amplitudes of any large or overlapping pulses, compensating by making them longer if needed. |
