Jul 11, 6: In reply to Wen-Shin Wang: The method is issued from the German standardization group VDE. The PCB material shall be compatible with the frequency range being sae j1752-3. The VSWR over the frequency range being measured shall beless sae j1752-3 1.

In these measurements, orientation A gives a spectrum 20dB under the customer limit, which sounds like a good news. In sae j1752-3, anysize or shape of PCB may be used that will mate with the wall port on the test cell used.

Other cells may not produce sae j1752-3 spectral output but may be used forcomparative measurements, subject to their frequency and sensitivity limitations. A 50 ohm resistance is placed on the far end of the cell. Do you have another question?
