I have a signal generator with BNC outputs, and a couple of AC voltmeters with only BNC connectors. I've a mix of RG58 (53.5Ω), RG59(73Ω), and might even have RG62 (93Ω) . Does it matter?
I've no idea what the output impedance of the signal generator a Wavetek 186. I've managed to hook it up to both a Fluke DVM and the HP, (they're not tube but solid state) to get a .316v sine wave, and it seems as long as the voltage of the sine wave at various freq's is correct that would be the the focus. I've a mix of RG58 (53.5Ω), RG59(73Ω), and might even have RG62 (93Ω). Does it matter for this purpose?
NOTE: My understanding is for clock & SP/DIF you need 75Ω. Second question, is RG59 close enough?
