.Item

Optional - Item is the default property of a collections object and therefore can be called implicitly. For example, the following two commands are equivalent:

Channels.Item(3).Averaging = 1
Channels(3).Averaging = 1

n

(variant) - Number of the item in the collection.

In addition, the following collections allow you to specify the name of the item as a string:

• The Measurements, Traces, and FOM collections. For example:
  measCollection("CH_S11_1").InterpolateMarkers

• The Cal Sets collection. For example:
  Calsets("MyCalSet").Description = "New Description"

• The ExternalDevices Collection. For example:
  Set extDev = externalDevices.Item("NewPMAR")

• The GuidedCalibrationPowerSensors Collection. For example:
  Set PowerSensor = GuidedCalibrationPowerSensors.Item.Name = "26GHzPowerSensor"
