FeedbackLoop | #121 - Bird SignalHawk SH-362S spectrum analyzer and VNA repair @feedback-loop | Uploaded 3 years ago | Updated 12 hours ago
The instrument had a couple of faults: some flicker and jitter on the display, and some noise in the signal in VNA mode mostly visible at lower frequencies. The flicker disappeared after reconnecting some internal connections. The noise was traced to a cracked soldering joint in the VNA module.
