content: If the price is an issue those very cheap ones, Do a lot of things, at least until your circuit is not that fast. Be more clear about your application.If money is not an issue look for the ones that have a shielded cable like this onehttps://es.aliexpress.com/item/32905798335.html?spm=a2g0o.productlist.0.0.4d3891d3C03zLz&algo_pvid=6c968720-6c61-4adb-ad43-67b76e70ca42&algo_expid=6c968720-6c61-4adb-ad43-67b76e70ca42-2&btsid=0ab6fa8115837277770918297ec5a6&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_To buy the unshielded one is a better option to buy the very cheap one aboveBy the Way, Pelé is better than MaradonaShielded one

content: thanks for the answer, mine is hobby, for that reason, I noticed a basic DSlogic, but I also don't want the lowest of the list of logical analyzers, the DSlogic Plus seems too expensive for my applications, but the decoder of Rigol DS1054Z sometimes falls short.in spanishgracias por la respuesta, lo mio es hobby, por ese motivo, me fije en un DSlogic basic, pero tampoco quiero lo mas bajo de la lista de analizadores logicos, el DSlogic Plus me parece demasiado caro para mis aplicaciones, pero el el decodificador de rigol ds1054z a veces me queda corto.

content: I have two analyzers for now in sight, around US $ 100.- that would be the maximum limit. For my pocket it would be the basic USB dslogic, but I do have to kill the pig.1- Zeroplus LAP-C 16032 logic analyzer2- DSlogic usb plusin spanishtengo dos analisadores por ahora en vista, que rondan los u$s100.- que seria el tope maximo. para mi bolsillo seria el dslogic usb basic, pero si tengo que matar al chanchito.1- Zeroplus LAP-C 16032 logic analyser2- DSlogic usb plus

content: Quote from: Adrian_Arg. on March 09, 2020, 06:05:18 pmThe LAP-C 16032 has only 100MHz sample rate (on all 16 channels) and it does not go up by reducing the channels, like the DSlogic plus, that can do up to 400MSa/s if using only 4 channels. The Zeroplus software only runs on windows. I have both and I used the Zeroplus for long time and the software is more stable. I switched to the DSlogic and I like the fact that the software runs on Mac OSX as well, but I found it resets frequently, I guess is was because of high current pull on standard USB 2.0 port. I purchased the DSlogic basic and "upgraded" to plus by soldering the extra SRAM and modifying the SPI EEPROM.

content: The DSlogic usb plus has a state clock input and this is an important feature. The 400 MHz sample rate is going to be plenty for most hobbyists, it will certainly cover my projects as I rarely clock external logic at more than 50 MHz.For $149, it seems like quite a nice device. I might very well consider it for my next LA. I currently have a DIY FPGA based LA and, of course, the Analog Discovery 2 has that capability as well although nowhere near as fast.16 channels is somewhat limiting, even 32 fell short on a couple of my projects but I can usually work around it.

content: Quote from: Adrian_Arg. on March 10, 2020, 07:45:55 pmI was working on a reincarnation of the IBM 1130 minicomputer in a Spartan 3 FPGA Starter Board. I routed a 32 bit debug bus through the various modules so that I could see, for example, how the disk drive (actually a compact flash device) was interacting with the DMA channel and the interrupt flag. There was a lot of state information that needed to be observed and this could often run well beyond 32 bits. So, I created internal logic flags that signified a particular event and fed those to the debug bus instead of the actual signals. It took a bit of thinking about how to summarize the data and output a flag but it all worked out fine.That particular board had 3 50-pin edge connectors so I could use just one of them for the 32 bit LA. One connector was all wrapped up in SRAM addressing so I didn't use it, the second connector was used by the LA and the third was used by the Compact Flash and a 4 channel FTDI serial<=>USB interface. Pretty busy!At times, I wish I had 64 channels! But I got over it. Sixteen channels would have been a struggle. It would have worked but there would be more head scratching to see what was going on.

content: Quote from: Adrian_Arg. on March 10, 2020, 09:58:24 pmThe ROMs appear to be available, maybe one day you can build an emulation. With FPGA technology, you can build anything you want. I don't know what you do for cartridges, maybe those have been dumped as well.The IBM 1130 was introduced in 1965 and I started working with it in 1970. At the time, it was the only machine that could be leased for less than $1000/month (probably the low end version). It was a great machine for an EE student when coupled with the IBM Electronics Circuit Analysis Progra (ECAP), a predecessor for all the SPICE tools.http://ibm1130.org/I still use my system for various projects, particularly those that benefit from the equivalent of the drum plotter. I like writing FORTRAN code.
