frequency of interest. Measure the peak output at the other end of the cable on the
scope through the 50 ohm termination.
Use the formula :
Example:
4-36
Cable
Assembly
dB = 20 log (V out / V in)
Info: If you use 1 volt peak for V in, V in = 1
At 750 kHz you get a reading of 160 mV
.16 v
log .16
x 20
-15.9 dB loss
