FeedbackLoop | #44 - HP 8590A spectrum analyzer repair - part 2 of 3 @feedback-loop | Uploaded 8 years ago | Updated 22 hours ago
In the previous video I replaced a par of blown diodes in the RF mixer of HP 8590A with Avago (Broadcom) HSMS-2802. In this video I experimented with HSMS-2812, HSMS-2822 and even with unmatched pair of 1N5711.
