b
Connect the network analyzer's reference channel to A10 J2 using
an N(m)-to-BNC(f) adapter and SMB(f)-to-BNC(m) cable.
c
Connect a 10 k
Ω
d Connect a 50
resistor.
e
Connect the network analyzer's source to the 50
termination using an N(m)-to-BNC(f) adapter and a BNC cable.
3 Normalize the measurement.
a
Wait for a complete sweep on the network analyzer.
b
Store the trace data in a storage register.
c Set the network analyzer to divide the reference channel by the
storage register.
