I recently purchased an older model HP8753 Vector network analyzer. It came
with the reflection test set and calibration standards.
I have looked for some time on the net and cannot find any documents that
describe how to make practical measurements.
Initially I want to characterise some passive components (caps etc) and I
also want to be able to measure the unput impedance of an active device.
Can someone please point me in the right direction or maybe explain how I
set up a test. I have seen responses in books showing the impedance of a
capacitor and the self resonant response but when I connect a Cap to the
test port on the reflection test set I can see the correct capacitance curve
on the Smith chart display but when I switch to mag, the line is flat acorss
the band. I cannot tell from the Smith Chart where it is self responant.
Thanks in advance for any help
