Agilent Technologies E1563A, E1564A Status System Registers, Subsystem Syntax STATus

STATus

The STATus subsystem reports the bit values of the Operation Data/Signal Register and Questionable Data/Signal Register. It also allows you to unmask the bits you want reported from the Standard Event Register and to read the summary bits from the Status Byte Register.

The Operation Data/Signal Register and Questionable Data/Signal Register groups consist of a condition register, an event register and an enable register. STATus:OPERation and STATus:QUEStionable control and query these registers.

Status System Registers

The STATus system contains seven registers, four of which are under IEEE

488.2control: the Standard Event Status Register (*ESR?), the Standard Event Enable Register (*ESE and *ESE?), the Status Byte Register (*STB?) and the Service Request Enable Register (*SRE and *SRE?).

QUEStionable Status Register

The QUEStionable Status register indicates failures as described in the following table. Limit failures occur at the sample rate so the condition register bits change rapidly and cannot be read until the measurement completes. You should read the EVENt register which latches the CONDition register once a measurement cycle to see if a limit failure occurred. You will then need to determine which reading failed by printing the reading number and the measurement value.

Bit #	Description
0	VOLTage overload
8	CALibration failure
9	Channel 1 limit failure
10	Channel 2 limit failure
11	Channel 3 limit failure
12	Channel 4 limit failure
