It appears to be a slide rule for determining the measurement error for oscilloscopes based on signal and probe characteristics. Find the manual for the 'scope pictured and maybe it'll have instructions. National Semiconductor once gave away similar slide rules for determining transmission line characteristics for PCB design, like trace impedance. I gave a set to a guy at work who collects slide rules and he hugged me! Dave Edit: Looks like TI has the calculator, now. http://www.ti.com/lit/an/snla035/snla035.pdf |
