In case folks don’t know about the “El Cheapo Special” - you can make very respectable 2GHz passive scope probes with 150ps rise times out of RG-174 coax cable and 1k resistors.<p>Clip the cable in half, solder the core to the 1k resistor, and the other end of the 1k resistor to the signal you want to probe.<p>Solder the shield braid to board GND.<p>50ohm terminate your scope, set probe amplification to 20x, and voila!<p>Excellent tip recommended both by Paul Horowitz (Art of Electronics) and Howard Johnson (High Speed Digital Design). Works like a charm!
