El tinySA es un analizador de espectro pequeño, destinado principalmente a 0.1MHz a 350MHz
Especificación: * Resolución de pantalla 320 * 240 píxeles * Pantalla diagonal 2.8 pulgadas * 16 bits por píxeles RGB * Control táctil resistivo * Control de interruptor Jog * Control de puerto serie USB * Puerto opcional TTL USART (NO implementado) en el PCB interno * Fuente de alimentación lineal para evitar el ruido de conmutación.
Analizador de espectro con dos entradas, entrada MF/HF/VHF de alta calidad para 0.1MHZ-350MHz, entrada UHF de menor calidad para 240MHz-960MHz.
Filtros de paso de banda de resolución conmutable para ambos rangos entre 2,6 kHz y 640 kHz
Pantalla a color que muestra 290 puntos de escaneo que cubren hasta el rango completo de frecuencia baja o alta.
Atenuador paso de entrada de 0dB a 31dB para la entrada MF/HF/VHF.
Cuando no se utiliza como analizador de espectro se puede utilizar como generador de señal, salida de seno MF/HF/VHF entre 0.1MHZ-350MHz, salida de onda cuadrada UHF entre 240MHz-960MHz.
Carga USB
Tiempo de carga máximo 1 hora en puerto USB mínimo de 500 mA o cargador USB. Funcionamiento con batería completamente cargada durante al menos 2 horas
Control de PC
La interfaz USB implementa el protocolo Serial over USB (CDC) y hay un gran conjunto de comandos que se pueden invocar a través de la interfaz serie. Estos comandos se pueden utilizar para realizar mediciones o actualizar la configuración interna. El controlador para Windows se instalará automáticamente después de conectarse a una PC con Windows. El controlador para Linux está integrado en el kernel

On-line Reviews of this product mention that it is available for around $50. What is puzzling me is the high Amazon price.

El rango dinámico es bastante escaso por lo que algunas pruebas no las puede hacer.

Radio frequency spectrum analyzers can be very expensive, heavy and complex. Only in the last couple of years has the technology been available, at a reasonable performance level and portability.TinySA (and it's big brother, TinySA Ultra) and RF Explorer are the leading breakthrough products in Spectrum Analyzers. They each excel at different aspects of measuring RF and , all in a similar price ballpark.The original TinySA is by far the cheapest, at around $60-70. It is also the most feature-limited (though it is very full-featured by historical measure). It is marketed largely to ham radio operators, but I bought it to sniff out RF interference that might affect my wireless microphone systems that I use for my documentary work.Documentation is a bit sparse, as this is designed and supported essentially by a single person. There is no documentation in the box. However, there is a Wiki and series of short tutorial videos created by the developer to cover setup and menu controls. Most third-party reviews and video tutorials focus on ham radio and other use-cases that are unrelated to my needs.The TinySA's 0-950mhz band width is perfect for me to sniff out the UHF band from 470-608mhz (the remaining legal bands in the US) for interference sources. This device is described as "less accurate" in the 350mhz and up band, but it's plenty accurate enough for me.If I was coordinating large numbers of wireless mics for a venue or a large production, this would not be the best tool for me. I would be much better served by the 3x more expensive RF Explorer, which has a decent desktop computer application and can export frequency scans to a file that can be read by Shure's industry standard free frequency coordination app ( must, if you are looking to coordinate large numbers of RF sources. RF Explorer is a professional standard in portable RF test gear that can interface with the apps for advanced analysis and frequency coordination.TinySA Ultra has a bigger screen and extra bells and whistles and boasts a much broader range of frequencies it can scan (including way up into the wifi range) but if you just need a very portable, reliable, inexpensive standalone RF "sniffer" to help you avoid and solve RF interference problems in frequency ranges up into the UHF range, TinySA does the job beautifully.

This is overall a pretty decent spectrum analyzer for the price. Good for hobbyists, but I would not say it's good for much else.It's small and portable.I can't fully vouch for the accuracy of it, but the few items I've tested with known frequencies, it picks up fairly well.The only negative feedback I have for this product is that the touch UI is super finicky and the screen calibration seems to be off. But other than that, like I said, good for hobbyists

The TinySA works just fine! And so far in testing, the accuracy of this device is not to bad.First thing, an ACTUAL instruction manual would have been really nice. There is no documentation at all on how to operate the TinySA. Luckily there are several YouTube vids out there to help you along..The menu IS a bit confusing.... There is a lot of back and fourth in the menu to set the parameters you desire. Once again, nothing is clearly explained. The “LISTEN” feature seems to be disabled, this allows you to listen in on the frequency being monitored. I don’t even think there is an actual speaker in this unit. This is my MAJOR DISAPPOINTMENT! As this feature would have been very handy from time to time.When doing the SELF TEST of CALIBRATION, the high and low ports must be connected together with the supplied jumper cable!!!If you do not follow this procedure, the unit will fail the test and not calibrate correctly.For the price, it’s definitely a great unit and worth every penny....... Just watch the videos on how to use and setup the TinySA, as I stated..... It is a bit confusing to operate.

It obviously has some limitations, especially resolution bandwidth, image rejection and scan speed but for the price and size it is extremely useful. With careful use, some external attenuators and filters it is capable of quite good accuracy and performs 90% of the tasks you want an SA to achieve. There is no tracking generator but a noise diode is an easy to build replacement for many uses - however you may as well just buy a NanoVNA too which has a reflection bridge built in. Heck with some software you can even use an NanoVNA as a tracking generator for the TinySA but it isn't a very pure source and would need filtering.The antenna that comes with it is very fragile. I broke it quickly. The connection between the telescoping bit and the SMA connector is implemented in a very thin-walled metal tube just after the hinge joint where it passes through the white insulation. It snapped at this point without a lot of pressure while attempting to move the hinge joint which was fairly tight when I received it. I'd recommend slackening the screw in the hinge a little to minimise the force needed and reduce the risk of breaking the thin connection to the SMA center pin.
