Im in the process of calibrating a previously dead tektronix 564 oscilloscope (half tube half transistor).
The manual says "Connect the calibrator output to both inputs using a bnc 'T' connector and a 50ohm cable"
I have a heck of a time understanding impedance matching so I want to run this by you guys
The calibrator is on board the oscilloscope and I have a rg 59 cable going from that to a bnc T which is plugged into channel 2 and the other side to another rg 59 which goes to another T. One side of that T is plugged into channel 1 and the other is terminated with a 50 ohm bnc termination resistor.
Does the 50 ohm resistor pull the otherwise 75 ohm cable down to 50?
