*OPC?
Returns an ASCII "1" after the command is executed.
*WAI
After the command is executed, it prevents the instrument from executing any further
query or commands until the no-operation-pending flag is TRUE.
*PSC {1|0}
Sets the power-on status clear bit. When set to 1 the Standard Event Enable register
and Status Byte Enable registers will be cleared when power is turned ON. 0 setting
indicates the Enable registers will be loaded with Enable register masks from non-
volatile memory at power ON.
*PSC?
Queries the power-on status clear setting. Returns 0 or 1.
*ESR?
Queries the Standard Event register. Returns the decimal value of the binary-
weighted sum of bits.
*ESE <value>
Standard Event Enable register controls
which bits will be logically OR’d together to
generate the Event Summary bit 5 (ESB) within the Status Byte.
*ESE?
Queries the Standard Event enable register. Returns the decimal value of the binary-
weighted sum of bits.
*STB?
Read the Status Byte. Returns the decimal value of the binary-weighted sum of bits.
*SRE <value>
Service Request Enable register controls which bits from the Status Byte should be
used to generate a service request when the bit value = 1.
*SRE?
Queries the Service Request enable register. Returns the decimal value of binary-
weighted sum of bits.
Status Reporting
The status reporting system is configured using two types of registers. An Event
register and a Summary register. The Summary register is known as the Status Byte
register and records high-level summary information acquired by the Event registers.
