I've been playing with my new distortion analyzer and decided to test a few resistors. Raw data like this could be interesting to AKers, so here's a dump.
The attached ZIP file has 23 PNG images taken with a very simple test fixture that puts a 10K test object (DUT) in series with a high-quality 1K wirewound resistor and applies 12.86Vrms at 1KHz across the DUT (14.14Vrms total). The analyzer looks at voltage across the 1K resistor, which is an accurate function of current through the DUT. The file names include a rated wattage field (.25W, .5W, etc), a type field where:
cc = carbon composition
cf = carbon film
mf = metal film
mof = metal oxide film
ww = wire wound
... and a sample number. The file designated 'bypass' was obtained with generator and analyzer directly linked and with the generator output dialed down to 1.286V. All of the carbon comp resistors are old stock.
