Hi DC blocked 50 ohm terminations are indeed a bit odd. One answer is to simply use the 75 ohm version and move on. The gotcha there is that they may / may not have a block that works well at 10 MHz ( = the cap is to small ). The one thing *not* to do is to run the device with no termination on the cable. The gizmo will be perfectly happy. Your lab will be a mess. The coax will normally be long enough to make a great antenna at 10 MHz. Leaving the end un-terminated puts it in “antenna mode”. You will have RF all over everything. I have a lot of experience with this specific problem …..
