Common Commands 12-5
If a command error (CME) occurs, bit B5 of the Standard Event Status Register sets. If a
query error (QYE) occurs, bit B2 of the Standard Event Status Register sets. Since both of these
events are unmasked (enabled), the occurrence of any of them causes the ESB bit in the Status
Byte Register to set.
Read the Standard Event Status Register using the *ESE? query command.
