In this episode Shahriar extensively reviews the Rigol DSA1030A-TG3 Spectrum Analyzer. A wide variety of experiments are performed using the Rigol spectrum analyzer to serve both as a tutorial to use the instrument and to demonstrate its capabilities. Some measurement results are also performed using other calibrated instruments to verify the accuracy of the spectrum analyzer. The Rigol DSA1030A-TG3 can be purchased directly from Rigol Inc.
The following experiments are performed:
1) Signal amplitude, frequency and phase-noise measurements.
2) Low amplitude signal measurements (< -130dBm).
3) Low frequency measurement capabilities (< 9kHz).
4) PRBS length calculations and characterization.
5) Wireless 2.5GHz FM signal transmission and demodulation.
6) Attenuator and band-pass filter response measurements.
7) Amplifier bandwidth and output compression measurements.
8) Calibration and measurements of VSWR using the tracking generator.
9) Characterization of the tracking generator signal quality.
What brand are those power leads you used to feed DC to the OCXO, right near the 11:00 mark? I haven’t found anything like them from Pomona or EZ-Grab. Thanks, very helpful videos…

Man, he must have $50k worth of equipment!
regarding this SA, for $6k, I feel there are better choices, namely LP Tech LP-3000 for the same price (including TG).
Great video! Is it possible to use the DSA1030A to measure the performance of a Bluetooth antenna? I mean the bandwidth is enough for 2.4 GHz but do I need to consider harmonics above the 3GHz bandwidth of this spectrum analyzer?
You will not be able to see any frequency content above 3GHz using this spectrum analyzer alone. However, if you use an external mixer, you can down-convert the frequencies of interest down to below 3GHz.
Very nice exposition. Thank you.
If possible, might you explain and demostrat how the power sweep function on the tracking generator might be useful? I am guessing that it has some advantage over just using the normalize function.
The power sweet can be used to compensate for the losses of your cables, connectors, etc. By applying a power sweep as a function of frequency you can ensure that your DUT receives constant power across all frequencies.
Outstanding video as always, Shahriar. Thanks very much.
Thank you!
