Thanks - looks really nice.

For checking SMT active devices, the engineers I used to work with, used? fixtures with toggle-clamps to hold the DUT in place. On Wednesday, October 23, 2019, 12:37:42 a.m. GMT-4, Daniel Marks <profdc9@...> wrote:
I made a fixture PCB for my VNA and I think it would be useful as well for the NanoVNA.? You can find it at: It has the following features: 1.? Calibration standards for open, short, load, thru for SMA and BNC 2.? Four spots to solder on 0805 SMD components to create test loads for SMA, and an area left so that one can label the loads. 3.? ZIF socket for leaded component testing, both SMA and BNC 4.? A spot to place a spring clip into the board so that you can lay components flat against the board and clip them in to test them. I do not think these calibration standards will necessarily work out to 900 MHz but should be useful for convenient testing at HF/VHF. A picture of the test fixture is below. Dan |
