Hello John,
It depends on your requirement. It would be ok for signals up to 100kHz. The disadvantage would be the higher capacitance of the normal coaxial cable. Probe cables have only half the capacitance of 50Ohm coaxial cables.
I don't agree.
The most important thing is the distributed series resistance of the inner conductor. A value of 100 to 200 Ohm per meter gives the best pulse performance. If you would make a 10:1 probe using a normal coaxial cable, you would have nearly 100% overshoot for rise times below ten nanoseconds.
Best regards, Helmut
