*ESE?. Data is returned as a binary-weighted value. The Event Status Enable Register is written to by

of ESR register results in setting of ESB status register. ESE register value can be modified by

command *ESE followed by value of mask register (integer in range 0 –255). Reading of the register

can be performed with command *ESE?. The register is automatically reset after switching on. The

The Output Queue stores response messages until they are read from control unit. If there is at

Error Queue

The Error Queue stores error messages. They are placed in a "first in, first out" queue.

The queue is read destructively using the query command "SYSTem:ERRor?" to obtain a code

number and error message. The query "SYSTem:ERRor?" can be used to read errors in the queue

until it is empty, when the message "0, No Error" will be returned.
