Característica:
La frecuencia de muestreo de cada canal es de 24M / s; En realidad, 10M es suficiente para hacer frente a una variedad de ocasiones.
8 canales: puede recopilar señales cuando analiza datos, como I2C, UART, muestreo y análisis.
Cómo usarlo:
Paso 1. Descargue sigrok PluseView (https://sigrok.org/wiki/Downloads) e instálelo.
Paso 2. Conecte el analizador lógico a un puerto USB.
Paso 3. Ejecute el instalador del controlador Zadig (en la carpeta C: 'Archivos de programa (x86)').
Paso 4. Ejecuta PulseView. Conecte el cable a la señal (CH0, por ejemplo) y los pines a tierra en el analizador lógico en un extremo y los puertos lógicos (salida digital D3 o lo que sea en el para Arduino) en el otro extremo.
Paso 5. Escriba un pequeño boceto para generar una forma de onda PWM en D3 y haga clic en el botón "Ejecutar" en PulseView y ahí está en la pantalla de PulseView.

Le clip non hanno nulla da vedere con i femmina in femmina dovuto saldare dei pin... poi i PIN sul device si sono strappati verso l'interno...le ho risaldati col wire wrap perché le piste si sono tranciate...per 20 euri nn posdo pretendere di piu

This logic analyzer is an excellent value for what you spend. It works well with Saleae Logic software; however, if you're freshly installing the application, you must update your system's permissions, otherwise the application will not recognize the device (this applies to Linux; Windows may require a different approach).The only issue I had is that the jumper wires included aren't compatible with the clips without modification (ie pop one end off of the jumper wire, disassemble the clip, insert exposed end of wire into top of disassembled clip cap, solder the exposed end of the wire to the rivet inside of the clip, reassemble the clip).However, it feels kinda weird complaining about minor assembly/modification in hobbyist grade electronics, so I won't.

Por el precio que cuesta esta muy bien. El unico problema es que las pinzas no se pueden conectar directamente a los conectores hembra que trae. Se puede solucionar soldandole unos pines macho a la lengueta trasera de las pinzas. Por lo demas es una herramienta maravillosa para analizar comunicaciones y datos en un bus.

El analizador y su software de apoyo (bajarse aparte, de uso libre) funciona correctamente.Le pongo 4* por eso, pues me permitió localizar un fallo en un I2C de mi proyecto, y por este precio...Pero las pinzas son inútiles, tal como vienen: no se pueden insertar los cablecillos, pues la entrada de conexión no es, en absoluto, compatible.Como aparece en fotos de otro contribuyente, para poder usar esas pinzas: hay que abrirlas (fácil) y luego soldar en un hoyuelo que tienen un cablecillo oportuno, para poder luego enchufar ese hilo a los conectores del analizador.Trabajo innecesario si los suministradores hubiesen incluido pinzas de verdad compatibles con los conectores.

First of all, recommended. It actually works. Initial test on Microchip PIC on the hardware I2C bus @ 100kHz w/Sigrok 0.4.0 on Linux Ubuntu 18.04 host. I2C decoder works great!And now the notes:- Pulseview does not recognize the device running in a Win10 VM with Linux Ubuntu host under VMware Workstation 16.1.x. This is documented on Pulseview website. So I wouldn't recommend you try this. But native install on the host OS works just fine.- Pulseview (sigrok actually) has an install package for Ubuntu. sudo apt-get install sigrok gets you everything you need. It is true that to see the device as a user, you need to install udev rules. However, if you are ok with this, 'sudo pulseview' takes care of the permissions issues and it works without adding the rules. You can also install the AppImage as an alternative if you wish.- If you install the Win10 version, there is significant documentation provided in .pdf and .html including information on install. Otherwise, see here https://sigrok.org/doc/pulseview/unstable/manual.html- The I2C decoder (added by just clicking on the decode button and then selecting the signals) works right out of the shoot I did notice that with pre channel trigger set to 0, it would miss a couple of bytes at the very beginning. Setting the pre channel trigger to 10% fixed this. So a minor thing to be aware of.- Overall, the GUI is fairly intuitive and simple. I just clicked around and was able to get it to work without reading the manual.- Frankly, the only thing I could ask the vendor is to have matching color clips for the wires. Since colors are expensive, I am sure, maybe just some adhesive dots on white clips would be an alternative. Not a biggie.- Best $13 I've spent in quite a while

I'm a software engineer and I like to build stuff with raspberry pi and arduino for fun. I have an old four trace oscilloscope and a cool little LCD credit card sized 2 trace scope. The scopes are useful enough, but I wanted to do a little more digital signal analysis on one of my projects. I bought this as a "why not, its less that $15 dollars, worse comes to worse, I'll return it."Well, it didn't go well at first. The software was not all that intuitive to install. I use raspbian for the raspberry pi and ubuntu for my laptop. Both had PulseView and both installed just fine. Problem is that it didn't work!!! I thought the device we defective. It turns out that the drivers for it are kind of optional and required an extra step of installing sigrok as well.After that, it performed pretty well. My first test was to examine the I/O between a raspberry pi and an ultrasonic range finders. It did a good job.If you are just hacking small hardware projects, this little thing is amazing. If you are doing something hard core or with much faster signal rates, this is probably not for you. If you are building something on an protoboard with a SBC, this is perfect. It's now a useful part of my tool chest.

The LA itself appears to work flawlessly with PulseView. It comes with a shrouded/keyed ribbon cable connector, but the supplied ribbon cable has a bunch of single ends on it. No problem; just shove the singles onto the connector one at a time, following the diagram on the unit and your desired color-code. I guess you might call that a "feature" if you want to code it differently?Speaking of color-coding, the standard resistor colors match the unit if you use a straightforward order (CH1/PIN1/brown, CH2/PIN2/red, etc.), but they're off by one in PulseView (CH0/black, CH1/brown, etc. map to physical CH1, CH2, etc.). Just keep that in mind. In light of the previous paragraph, you could re-code it, but black is on the wrong side of the ribbon to make that pretty.The clips don't have the familiar pegs on the sides that I'm used to putting single pin headers on. Tennis4Ever said in his review that he had to solder them, so I tried to think of how to get my pencil into that tiny hole. Eventually I figured out that you can pull the cap off. Then you get a solderable tab in the big wide open. Stick a wire to that, let it cool, and put the cap back on. Then it's up to you to figure out how to connect that to the LA.-1 for the clip design and no manual to explain it.

Analizador lógico barato y fácil de usar. Yo lo uso con el software PulseView y el driver de SigRok.Recordad que no es un osiloscopio y no puede leer valores analógicos, sólo señal digital.
