Testing the AE20401 5.8 GHz Frequency Counter / RF Power Meter kit from Ascel-Electronics.
Here testing a dummy-load for return loss @ 2,2GHz generated by the MiniVNA (old style) and the Extender. I measure 29.5 dB which equals about 1.07 in VSWR. Pretty good for this kind of equipment at these frequencies.
Meter hooked up the computer. The meter has a type A female USB jack so I had to make an odd Type A male to Type A male cable to get it connected. I have no idea why they have chosen to use this kind of jack in the instrument.
