I have a trusty old Sound Technology ST1000A FM generator and I have a
question regarding the variable FM output level. The owner's manual states
that the output impedance is 50 ohms, VSWR1.3, 200Vdc isolation. My
question is if I am using this device to check the sensitivity of an FM
tuner, will the output level be affected if I connect the output terminal to
an RG-58 cable and then use a 75 ohm to 300 ohm matching transformer to make
it compatible with the old FM tuners? It seems to me the 2:1 step up ratio
of the matching transformer should affect the level not even considering
the fact that the 75 ohm input of the matching transformer does not match
the 50 ohm output of the cable.

Thanks for your reply.
