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

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
