I am driving a waveguide setup directly off the PNA-X via a coax-to-waveguide transition. This is a one-port measurement with my DUT attached to the waveguide. I would like to improve stability by using my ECal unit to correct for system drift caused by cable motion. I'm basically looking to treat my waveguide system like the 85070E software treats the probe and refresh the ECal calibration over time. Is this possible with a PNA unit alone, or do I need some specialized scripting that is not available directly in the PNA but has been written into the 85070E software? I already have cal kit for the waveguide unit set up with a short, offset short, and a load as standards.
