Are you measuring these resistors in circuit???? I have never seen resistors like these decrease this significantly in value unless they have been "cooked"?(burnt).? ?Your data does not make a bit of sense.? Don't mean to offend you but I have 64 years of experience along these lines so what do I know about basic electronics???? ? ? ?Terry On Wednesday, March 16, 2022, 01:03:26 PM CDT, Mike Merigliano <mmerig@...> wrote:
The EXT HORIZ function of my Tektronix 453 does not work, and I found some resistors that were way-out of specification. They are:
R634 (reads as 550, should be 11K)
R644 (reads as 4k, should be 10K with 1% precision)
R646 (reads as 1.37 K, should be 820K)
The signal diminishes as it enters the resistor network. Everything else looks okay.
i know the part numbers, the power ratings, and the precision, but originals are hard to find. I assume that carbon film or metal film would work okay, Any recommendations as to the kind of resistor to use?
