To implement 50 Ω coax measurements, customers can order a 50 Ω coax cable such as ACX2382-ND from DigiKey. Simply cut the coax in half to create two coax measurement cables. Strip a small portion of the insulating sheath at the end of the cable, twist, and tin the shield to create the ground connection. Use an external 50 Ω BNC feed through terminator (ARFX1069-ND or 501-1036-ND) and set the scope to AC coupled, 1X, with bandwidth limiting off.
