RIGOL DSA815-TG Spectrum Analyzer, Sweep Type, 9kHz~1.5GHz, Resolution Bandwidth 10Hz~1MHz, Display Average Noise Level -155dBm, with Tracking Source, EMI Option Included

Well versed usable Analyzer , with a reasonable range of features. Accurate and reliable A brand you can rely upon. A must have for anyone working in amateur radio , repair and design. Very happy.

Ordered this SA , received today , box tatty , opened the already weary box and no instructions , no power lead , nothing but the unit ?. WHY ? .. Is this a used returned unit ? . Looks like i will return it and look at other makes , not happy with it at all...

Ottimo strumento da laboratorio con licenza EMI instalata. Le funzioni di misurazione avanzata ed swr sono fornite in versione trial e costano vome lo strumento nuovo. Peccato Buona comunicazione con il venditore

Todo perfecto, producto impecable. Cumple las especificaciones y se entregó rápido y sin problemas. Recomendable como analizador de espectro de entrada (es el mas básico de la gama)

Je n’avais plus d’analyser de spectre depuis que j’ai quitté le boulot : grace à amazone, j’ai pu en acquérir un à un prix raisonnable !

The delivery was ahead of expected date. Shipping was quick. Product arrived interacted. Great value for the functionality and quality of the equipment.

The DSA815-TG is a very good value for its price. Anyone who has tried to tune up RF filters and duplexers without a spectrum analyzer and tracking generator while doing it manually knows that sometimes you are shooting in the dark. With the Rigol DSA815-TG you can see the response, where the peaks and notches are and make the adjustments. With the right adjustment of the span and the RBW (Resolution BandWidth), you can read notches to -100 db as the noise floor drops when the bandwidth narrows. Wide spans and very narrow bandwidth can take a lot of time to trace, but that is usually reserved for a final picture once the adjustments are made. The tracking generator is necessary for anybody serious about cavity and duplexer tuneup. For example, in tuning a used UHF duplexer I found that the isolation would suddenly go away as I turned the notch piston capacitor in the duplexer beyond a certain point. It is possible the capacitor might have been damaged by too much tweaking by a previous owner, or damaged by lightning. I backed off the adjustment and still had lots of isolation for the system. The alternative would be not to use the duplexer since I did not know what happening had I not been using the DSA815-TG. In another instance, the duplexer had two notches that could not be completely merged by adjustment, probably because I was about 8 Mhz out of band on the duplexer, but there was still lots of isolation and the duplexer was still very usable and is now inservice. Once the adjustments are complete, you can print-save a copy of the screen to a USB for later reference. Although once adjusted, duplexers usually should not need readjustment for a long time, but this is still a great resource when checking the duplexer later to remember exactly what the final results were. The only hit is I do not understand the reasoning for locking out VSWR measurements unless you pay for a kit software/hardware license upgrade. This is a matter of convenience because you can find VSWR with a return loss bridge and chart. Calculating VSWR is not complicated and they could still sell a hardware kit if they like. For that matter, all the accessories are very expensive, but considering the basic functions of the DSA815 that you get for the initial price, it is a good value.
