Re: Power meter E4416A problem power on

 

¿ªÔÆÌåÓý

The switch contacts are laminated into the front panel overlay.? Cheap to manufacture but the failure rate is high after 4-6years of constant service.? The part number is E4418-66502 Key Flexi Circuit ($302 from Keysight) and is used in the E4416, 17, 18, and E4419.? It might be cheaper to buy a defective power meter and scavenge it for the overlay.? You can search ebay for front panel overlay and you should find some for sale.? I've seen prices range from $30 to 125.00 on ebay and they're all selling the same item that is of course, Make in China. . . .? There are some listed now for $27, titled For Agilent/HP E4418A/B /E4416A/E4419A/B/E4417A Press Key Film membrane keypad

You're going to have to replace the keypad assembly, this is a very common problem in all the new series of instruments and the E19xx series of meters.
Price isn't too bad and you can find them for much less on Ebay.
