For the MSO2000 and MDO3000 Series, the thresholds are adjusted per probe pod (a grouping of 8 channels) and therefore, the TTL signals would be on one pod while the LVPECL signals would be on the second pod. How To Completely Check The High Voltage Circuit In CRT Monitor/Television. If you already own an oscilloscope you will find it useful occasionally, but it is not worth buying one for valve radio work alone. Oscilloscopes are in stock and ship same-day at Mouser Electronics from industry leading manufacturers. Check out my new article on how to build an Arduino oscilloscope with 7 lines of code.
