HotVNA-S -- NA-SpecialX
HHF is leading in vector hot S-parameter measurements including the test-set design around 2.45 GHz. Our meanwhile established product HotVNA-S allows to perform calibrated complex S-parameter measurements with our VNA-modules. However, every hot-S-parameter configuration is costumer specified.
Often, you need to test your high power components under high power conditions! The drift of the phase is often a very identification of process control, management or detection for instabilities.
HotVNA-S is optimized to test microwave ovens as well as passive components like GHz-plasma, wave guides, cables, connectors, filters, antennas and more. Manufactures of these components can used HotVNA-S to perform accurate tests with typ. 6000W and much more.
A typical configuration of a HotVNA-S-instrument for 6000 W and 2.45 GHz is shown in Fig. 1.

This VNA-hot-S-parameter measurement system consists out of a high power magnetron and other high power parts from the company Fricke und Mallah (:fm) and the 250W PA as well as the VNA-modules from HHF.
One full architecture of this HotVNA-S for one-port measurements is given in Fig. 2.

HHF sells this costumer defined measurement places with an open python-software. The included necessary calibration standards are shown in Fig. 3.

It is well known, that the calibration quality can be tested by the ripple test. Fig. 4 shows the very good results from the open python software.

Hot-S-parameter measurements are necessary to characterize in the R+D-world the DUT in real conditions or to perform in the production world a perfect process control. Fig. 5 shows the very good results from the open python software including the measurement errors of the 6kW signal at the both sidebands of the receiver.
