Awesome, thank you! Can you post them here, or are they too big?

What kind of rack? Standard 19" or something smaller? I want to make a narrow rack for my bench gear.

Found two, the last from May2023.
After removing names and other sensitive data I´ll upload it here.
A little disappointment is that they´re using testfrequencies up to 10khz max.
But they will have their reasons to do so I guess.

Here are the dumps of the I2C EEPROMS (the B85RC64TA, and the AT24C512)
They should be exactly 8K and 64K bytes.

What do you consider low TC? There's a pretty huge range available. I'd like to get the best option without paying too much per resistor.

Is 25ppm/C good enough? I have some in my cart that range from 5ppm to 25ppm/C.
nctnico:
What is the spec of the LCR meter? If you want some calibration worthy standards then get parts that are 10 times better. In some designs I use 0.01% 2ppm SMT resistors as references (which are calibrated using a 6.5 digit DMM later on). These resistors are like 15 euro each from Mouser IIRC.
