*ESR?

Meaning and Type

Event Status Register Device Status

Description

This query reads the Standard Event Status Event register. Reading the register clears it. The bit configuration of this register is the same as the Standard Event Status Enable register (*ESE). See "Chapter 4 - Status Reporting" for a detailed explanation of this register.

Query Syntax

*ESR?

 

Parameters

(None)

 

Returned Parameters

<NR1>

(Register binary value)

Manufacturer

 

xxxxA

4-digit model number followed by a letter

 

nnnnA-nnnnn

10-character serial number or 0

*OPC

Meaning and Type

Operation Complete Device Status

Description

This command causes the interface to set the OPC bit (bit 0) of the Standard Event Status register when the power supply has completed all pending operations. (See *ESE for the bit configuration of the Standard Event Status register.) Pending operations are complete when:

•All commands sent before *OPC have been executed. This includes overlapped commands. Most commands are sequential and are completed before the next command is executed. Overlapped commands are executed in parallel with other commands. Commands that affect output voltage, current or state, relays, and trigger actions are overlapped with subsequent commands sent to the power supply. The *OPC command provides notification that all overlapped commands have been completed.

•Any change in the output level caused by previous commands has been completed (completion of settling time, relay bounce, etc.)

•All triggered actions are completed

*OPC does not prevent processing of subsequent commands, but Bit 0 will not be set until all pending operations are completed.
