Lab 2.
Seeing in
frequency.
A working 3D bench with a spectrum analyzer, a two channel function generator and the KL-93002 AM modulator. See the odd harmonics of a 10 MHz square wave, then the carrier and sidebands of a tone modulated AM wave, and learn what the span and the resolution bandwidth really do.

Your details
When you enter, your name, ID, section and network (IP) address are recorded for attendance. Your readings and report stay on this computer.
01
Read the concepts page: Fourier series and transform, square wave harmonics, tone AM lines, span and resolution bandwidth.
02
Guided mode walks through Exercise 1 and Exercise 2 of section 2.2 and ticks each step when the bench is really set.
03
Record the analyzer screen for each exercise and export a PDF sheet with the spectrum captures and marker values.
