Bit No. Meaning

0 Operation Complete

This bit is set on receipt of the command *OPC after all previous commands have been

executed.

2 Query Error

This bit is set if either the controller wants to read data from the instrument without having

sent a query, or if it does not fetch requested data and sends new instructions to the instru-

ment instead. The cause is often a query which is faulty and hence cannot be executed.

3 Device-Dependent Error

This bit is set if a device-dependent error occurs. An error message with a number

between –300 and –399 or a positive error number, which describes the error in greater

detail, is entered into the error queue. See also Chapter 10, "Error Messages and Trouble-

shooting", on page 1417.

4 Execution Error

This bit is set if a received command is syntactically correct, but cannot be performed for

other reasons. An error message with a number between –200 and –300, which describes

the error in greater detail, is entered into the error queue.

5 Command Error

This bit is set if a command which is undefined or syntactically incorrect is received. An

error message with a number between -100 and -200, which describes the error in greater

detail, is entered into the error queue.

6 User Request

This bit is set when the instrument is switched over to manual control or when a user-

defined softkey is used (see SYSTem:USER:KEY).

7 Power On (supply voltage on)

This bit is set when the instrument is switched on.
