Technical data

This command clears all status data structures in a device. For the Serial BERT,
these registers include:
SESR IEEE 488.2
OPERation Status Register SCPI
QUEStionable Status Register SCPI
Execution of *CLS also clears any additional status data structures implemented
in the device. The corresponding enable registers are unaffected.
See “Reading the Serial BERT's Status - Concepts” on page 24 for more information
about the Status Byte.
*ESE[?]
*ESE <NR1>
*ESE?
IAgilentN490xStatus.Register (not IVI-compliant)
The Standard Event Status Enable Command (*ESE) sets the Standard Event Enable
Register. This register acts like a mask, so that the next time a selected bit goes
high, the ESB bit in the status byte is set. See “Reading the Serial BERT's Status
- Reference” on page 27 for details.
For example, if bit 0 is set in the Standard Event Enable Register, then when the
OPC bit in the Standard Event register goes true, the ESB summary bit is set in the
Status Byte.
The query (*ESE?) returns the contents of the Standard Event Enable Register.
*ESR?
IAgilentN490xStatus.SerialPoll (not IVI-compliant)
*ESR?
This query interrogates the Standard Event Status Register. The register is cleared
after it is read.
