Hi all,
Today, we open up an Agilent E8361A 10 MHz – 67 GHz vector network analyzer which was reported to have an unlock error. After spending some time preparing for the repair, we try several methods through software and hardware to troubleshoot a suspected bad connection.
Ultimately, disassembling, cleaning, and reassembling most of the non-RF connections fixes the communication issue between a subassembly and the CPU. We conclude the repair by running the PNA Operator’s check to ensure that the source and receiver diagnostics all pass.
Stay tuned for more.
