Spectrum Analyzer for Beginners Rigol DSA815-TG Tutorial #spectrumanalyzer #DSA815 #rf #Rigol #hf

Spectrum analyzer basics in one video. This beginner tutorial teaches the Rigol DSA815-TG from the ground up — kept deliberately simple, no prior knowledge required. From the first key press to a finished filter measurement using the built-in tracking generator. ▬▬▬ What you'll learn ▬▬▬ • What a spectrum analyzer does (power over frequency, not voltage over time) • Core terms: span, resolution bandwidth (RBW), VBW, marker, ref level, attenuation • How to read the display (Ref, Att, sweep time, status line) • Setting up the AMPT menu properly • Measuring a 433 MHz radio module (TI CC1101) over a cable • Receiving a PMR446 signal over the air with a telescopic antenna (Max Hold trick) • Using the tracking generator: record a reference trace, measure a low-pass filter, find the -3 dB cutoff • Avoiding the classic beginner mistakes (span too wide, wrong RBW, wrong attenuation, missing adapter) ▬▬▬ Equipment used ▬▬▬ • Rigol DSA815-TG spectrum analyzer (9 kHz – 1.5 GHz, with tracking generator) – https://rigol.com • Tekbox RF Accessory Set (adapters, attenuator, BNC telescopic antenna) – https://tekbox.com • Coax cables N / SMA / BNC, adapters SMA↔N↔BNC • Attenuators 10 dB / 30 dB • Device under test: 433 MHz radio module with TI CC1101 • SMA low-pass filter for the 433 MHz band • PMR446 handheld radio ▬▬▬ Important safety note ▬▬▬ The RF input handles a maximum of +20 dBm (100 mW) continuously and 50 V DC. When testing amplifiers or unknown sources, ALWAYS put a suitable attenuator in line first. ▬▬▬ Next tutorial ▬▬▬ Coming up: analyzing buck converter noise with near-field probes and a first round of EMC pre-compliance testing.
