ExternalDevice Object

Description

ExternalDevice objects allow you to set properties and methods for each external device.

Accessing the ExternalDevice Object

Obtain a handle to an External Device by specifying an item in the External Devices collection.

Although the following example shows how to create a PMAR external device, you can substitute any supported external device for "PMAR" and DeviceType: "Power Meter".

Supported External Device Objects

ExternalSource Object

ExternalDCDevice Object

PowerSensorAsReceiver Object

ExternalPulseGenerator Object

 

dim app

Set app = CreateObject("AgilentPNA835x.Application")

dim externalDevices

Set externalDevices = app.ExternalDevices

dim devicecount

devicecount = externalDevices.count

externalDevices.Add "NewPMAR"

dim newExternalDevice

Set newExternalDevice = externalDevices.Item("NewPMAR")

newExternalDevice.DeviceType = "Power Meter"

newExternalDevice.IOConfiguration= "GPIB0::14::INSTR"

newExternalDevice.IOEnable = true
