WebDec 7, 2016 · You might look up "Hot S22" measurement, where you try to measure S22 of a power amplifier with a large signal coming out of it. Of course exceeding the maximum input power of the VNA is a bad idea. Aside from blowing up the VNA, even if you don't exceed the maximum recommended power, too much power can compress the mixers or … WebAs with transmission measurement, we must setup the N9340A’s parameter controls must be set up and open the tracking mode before making a reflection measurement. In particular, a signal separating device like an electronic bridge or directional coupler should be placed between the input and reflected signal. Figure 3 DUT Z0 Load port2 port1 port3

WebThe measurement of impedance at an amplifier's output while it is running is called a "hot S22" measurement. Hot S22 typically needs 2 ports to perform. This kind of measurement takes a lot of care to perform. Any time you have an amplifier being measured with a VNA, there is the chance of damaging the VNA due to the output power of the amplifier.
