A built-in spectrum analyzer
3 Series built in spectrum analyzer
See the built-in spectrum analyzer at work.
Whether you’re a spectrum analyzer expert or an occasional user, you’ll be able to put the built-in spectrum analyzer right to work. Unlike other oscilloscopes that offer FFT “spectrum analysis”, the 3 Series has a true spectrum analyzer built right in.
Not getting to the root cause of EMI failures can prevent you from shipping product. The 3 Series MDO with its built-in spectrum analyzer can help you sniff out sources of EMI fast.
Go beyond AC and DC theory to cover mixed signal designs with logic channels and built-in spectrum analyzer. Tek scopes have earned their reputation for reliability and are the brand of scope most often found in industry labs.
