SYSTem Commands 11

U2761A Programmer’s Reference 113

SYSTem:ERRor?

Syntax

SYSTem:ERRor?

This query returns the next error number and its corresponding message

string from the error queue. The queue is a first-in, first-out (FIFO) buffer

that stores errors as they occur. Errors are cleared as you read them.

Remarks

• If more than 20 errors have occurred, the last error stored in the queue

(the most recent error) is replaced with –350,"Queue overflow".

• If no errors have occurred when you read the error queue, the U2761A

responds with +0,"No error".

• The error queue is cleared by the clear status (*CLS) command or when

power is cycled. The errors are also cleared when you read the queue.

• Refer to Chapter 16, “Error Messages” on page 141 for the error

messages.

Example

The following query reads and clears one error.

SYST:ERR?

Typical response:

–101,"Invalid character"

SYST :ERR ?

1 2 ... 116 117 118 119 120 121 122 123 124 125 126 ... 168 169
