Can I measure the capacitance between two capacitor plates of 16453A dielectric fixture with an 4284A LCR meter?

I have the following pieces of HP/Agilent/Keysight equipment. I put some photos, just in case someone is not aware of the specific pieces

  1. 4291B material/impedance analyzer, with option 010, which is material measurement.
  2. High impedance test head for above.
  3. 16453A dielectric test fixture which has an APC7 (7 mm) connector at the bottom

 

The 16453A is supported with the 4291B,, so that combination works fine for measuring the permittivity of dielectrics.

 

I also have

 

  1. A 4284A LCR meter
  2. 16085B 4TP to 7 mm adapter

 

What I want to know is if there's any way to measure the capacitance of the dielectric between the plates of the 16453A fixture using the 4284A LCR meter and 16085B 4TP to 7 mm adapter. I realise this is not a supported configuration, so I'm not asking for how one might compute permittivity using the combination, but whether it is possible to measure the capacitance. The 4284A is an LCR meter, so in principle I'd expect it to be possible to measure the capacitance between the plates of the 16453A with a dielectric in place, but I don't know how. There's the obvious problem that if doing an open/short calibration, with the latch of the 16453A open, it is not a true "open".

 

There are two things I can eaisly do.

 

  1. Measure the capacitance between the plates of the 16453A using the 4291B
  2. Measure the capacitance of the complete 16453A fixture using the 4284A LCR meter

But neither of them address the problem I am trying to solve, which is how to measure the capacitance between the plates of the 16453A using the 4284A LCR meter and 16085B 4TP to 7 mm adapter 

 

I don't need someone to tell me the 4284A / 16453A is not a supported configuration, as I already know that. But I thought the 4284A would allow one to measure the capacitance of fixtures made by a user. In this case, I could easily consider the 16453A a user made fixture.
