TSP #64 - Repair of PXI-2596 (uWave Switch), PXI-4461 (SA) & PXI-4071 (7.5 Digit FlexDMM)
In this episode, Shahriar repairs a few PXI module cards including a PXI-2596 Microwave Switch, a PXI-4461 Signal Analyzer and a PXI-4071 7.5 Digit FlexDMM unit. The PXI-2596 and PXI-4461 have both suffered mechanical damage to the on-board components. Some re-wiring as well as component replacement is necessary to correct the problems.
The PXI-4071 module halts the PXI system boot up entirely. The card is missing a flash memory IC and could potentially have a bad PXI bus main IC. The PXI bus IC replacement does not correct the problem. This implies a missing firmware on the flash memory IC.
