Hi
I am trying to identifiy the impedance and
response of a device. I am using Agilent 4140B pico ammeter\D.C voltage
source. The way it is to be done is as following.
1.
Trigger the DC voltage to Dirac delta pulse (a waveform of infinite
amplitude with zero period), step function in real. The pulse will have
in it pulses of all possible amplitudes ideally. Subject the
transmissions lines of the device to pulse and read the response of the
device. The response should have signature of the device impedances.
2.
Generate a sine wave by trigger the DC voltage at various levels and
collecting them to form a waveform a period for a partciluar time. The
response of the device should have the signature of it and also let me
know information about the reflection, refraction, dissipation and
absorption. It is like impedance matching and transmission line
characterization.
I am having difficult in implementing the concept. Examples will be helpful.
Kindly advise.
Regards
Karan
