STATus:QUEStionable:ENABle

Syntax

STATus:QUEStionable:ENABle <enable_val>

STATus:QUEStionable:ENABle?

Description

This command enables bits in the enable register for the Questionable Data Register group. The selected bits are then reported to the Status Byte.

For more information on the Status System for the instrument, see Status System Introduction.

Used With:

34901A 20 Channel Multiplexer (2/4-wire) Module
34902A 16 Channel Multiplexer (2/4-wire) Module
34907A Multifunction Module (digital input and totalizer channels only)
34908A 40 Channel Single-Ended Multiplexer Module

Parameters

Name Type Range of Values Default Value

<enable_val> Numeric An integer from 0 to 65535, specifying the bits to enable as a bit sum. This is a required parameter.

Use the <enable_value> parameter to specify which bits will be reported to the Status Byte. The decimal value specified corresponds to the binary-weighted sum of the bits you wish to enable in the register. For example, to enable bit 0 (decimal value = 1) and bit 10 (decimal value = 1024), the corresponding decimal value would be 1025 (1 + 1024).
The *CLS (clear status) command will not clear the enable register but it does clear all bits in the event register.
The *RST command has no effect on this register.

Return Format

The query command reads the enable register and returns a decimal value corresponding to the binary-weighted sum of all bits set in the register. For example, if bit 0 (decimal value = 1) and bit 10 (decimal value = 1024) are enabled, the query command will return +1025.

Examples

The following command enables bit 9 (decimal value = 512) in the enable register.

STAT:QUES:ENAB 512

The following query returns which bits are enabled in the register.

STAT:QUES:ENAB?

Typical Response: +512

STATus:QUEStionable:ENABle
