Coarse Calibrations

[2011/06/14]: Some coarse calibrations are performed.

1. A full sweep 0-1000MHz after calibrations (VNA Transmission Mode).

2. Test on a HAM-DIY 7.023MHz Crystal after calibrations.

3. Spectrum analyzer mode after coarse calibrations.

A full sweep 0-1000MHz. There have some unwanted responses (320MHz, 960MHz, 64MHz, and 10MHz).

It looks like there have some leakages of 64MHz signal and it’s harmonics.
