Instrument Control Toolbox

ChassisIndex

Specify the index number of the VXI chassis

Description

You configure ChassisIndex to be the index number of the VXI chassis associated with your instrument.

When you create a VISA-VXI or VISA-GPIB-VXI object, ChassisIndex is automatically assigned the value specified in the visa function. For both object types, the Name and RsrcName properties are automatically updated to reflect the ChassisIndex value.

You can configure ChassisIndex only when the object is disconnected from the instrument. You disconnect a connected object with the fclose function. A disconnected object has a Status property value of closed.

Characteristics

Usage	VISA-VXI, VISA-GPIB-VXI
Read only	While open
Data type	double

Values

The value is defined after the instrument object is created.

Example

Suppose you create a VISA-GPIB-VXI object associated with chassis 0 and logical address 32.

• v = visa('agilent','GPIB-VXI0::32::INSTR');
  

The ChassisIndex, Name, and RsrcName properties reflect the VXI chassis index number.

• get(v,{'ChassisIndex','Name','RsrcName'})
  ans = 
      [0]    'VISA-GPIB-VXI0-32'    'GPIB-VXI0::32::INSTR'
