EmbeddedLO Object


Description

Provides access to the properties that allow measurement of mixers that contain an embedded LO.

Accessing the EmbeddedLO Interface

Access the  Interface through the IMixer Object.

Dim app As AgilentPNA835x.Application
Set app = CreateObject("AgilentPNA835x.Application")
app.Preset

' FCA Measurements can't share the channel with standard measurements
' Because preset creates a single measurement in channel 1, we first delete the standard measurement

Dim standardMeas As IMeasurement
Set standardMeas = app.ActiveMeasurement
standardMeas.Delete

' Create a Measurement object, in this case using the IMeasurement interface

Dim meas As IMeasurement
Set meas = app.CreateCustomMeasurementEx(1, "SMC_Forward.SMC_ForwardMeas", "SC21")

' See if this measurement object supports IMixer

Dim mixer As IMixer
Dim embeddedLO
Set embeddedLO = mixer.EmbeddedLO

Note: The Find Now feature on the Embedded LO dialog is performed remotely by doing a 'Single Sweep" with ELO enabled.  See example program.

 

See an example program that shows how to create and calibrate a standard SMC or VMC measurement or a fixed output SMC measurement.
