STATus:QUEStionable:CONDition

Description: Return the current value (condition) of the SCPI Questionable Status register. The follow-

ing table shows the bit assignments in the register:

Bit Value Definition

0 1 Voltage 1 = an internal power supply voltage is out of spec.

1 - 2 -- Not used always returns 0

3 8 Power 1 = there has been a power error.

4 16 Temperature 1 = a sensor has drifted by more than 4C from autocal.

5 - 7 -- Not used always returns 0

8 256 Calibration 1 = sensor requires calibration and/or zeroing

9 - 12 -- Not used always returns 0

13 8192 Instrument Summary

14 16384 Command Warning

15 -- Not used always returns 0

Syntax: STATus:QUEStionable:CONDition?

Returns: 16-bit register value (0 to 32767)

Valid Modes: Any

STATus:QUEStionable:ENABle

Description: Set or return the Questionable Enable mask value. This value is used to enable particular

bits for generating a service request (SRQ) over the GPIB when certain conditions exist in

the Questionable Status register. When a mask bit is set, and the corresponding STB bit

goes true, an SRQ will be generated. No SRQ can be generated for that condition if the mask

bit is clear. The bits in the Status Byte register are generally summary bits, which are the

logical OR of the enabled bits from other registers.

Syntax: STATus:QUEStionable:ENABle <n>

Argument: <n> = 0 to 32767

Valid Modes: Any

4.5.20 IEEE-488.2 Commands

The purpose of IEEE488.2 commands is to provide management and data communication instructions for the system by

defining a set of “*” commands (an asterisk followed by a three character code). These commands allow device control

and status monitoring, and are the basis for some of the commands of the SCPI STATus subsystem (see previous).

*CLS

Description: Clear Status command. This command resets the SCPI status registers (Questionable Sta-

tus and Operation Status), the error queue, the IEEE488.2 Status Byte (STB) and Standard

Event Status (ESR) registers, and the measurement.

Syntax: *CLS

Argument: None

Valid Modes: Any
