Logic analysers from well-known companies are usually quite expensive, however, for some time now, there have also been inexpensive providers with clones on the market. I got hold of such a clone to carry out a few tests with it. <\/p>\n\n\n\n<p>At this point, it must be said that I do not agree with how some clone manufacturers handle the intellectual property of well-known manufacturers. On the other hand, I am also not willing to spend several hundred euros privately for such a device if I only use it sporadically and not professionally. There is also free firmware and programs for these cheap things, which work and are sufficient for my purposes. Another consideration would be to build such a device yourself with an Arduino or similar. However, the finished solution already has a housing, a more or less standardized connection and is ready to use.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<h1 class=\"wp-block-heading\">Facts<\/h1>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\"><table><thead><tr><th><strong>Description<\/strong><\/th><th>Worth<\/th><\/tr><\/thead><tbody><tr><td>Channels<\/td><td>8<\/td><\/tr><tr><td>USB<\/td><td>Mini<\/td><\/tr><tr><td>LEDs <\/td><td>2<\/td><\/tr><tr><td>Maximum input voltage<\/td><td>-25V to +25V<\/td><\/tr><tr><td>Sampling Rate<\/td><td>100 Megabits per second<\/td><\/tr><tr><td>Bandwidth<\/td><td>25 megahertz<\/td><\/tr><tr><td>Analogue bandwidth<\/td><td>1MHz<\/td><\/tr><tr><td>Operating temperature<\/td><td>0\u201370\u00b0C<\/td><\/tr><tr><td>Input Impedance<\/td><td>1 Megaohm<\/td><\/tr><\/tbody><\/table><figcaption class=\"wp-element-caption\">LogicAnalyser \u2013 <br><br><br><br><br><br><br><br><br><br>,Data and Facts<\/figcaption><\/figure>\n\n\n\n<h1 class=\"wp-block-heading\">Areas of application<\/h1>\n\n\n\n<ul>\n<li>Analysis of digital circuits.<\/li>\n\n\n\n<li>Support for Arduino projects<\/li>\n\n\n\n<li>Analysis of communication between components<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Views<\/h2>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-1 is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"600\" height=\"254\" data-id=\"5074\" src=\"https:\/\/www.fambach.net\/wp-content\/uploads\/LogicAnalyzerTop.jpg\" alt=\"\" class=\"wp-image-5074\" srcset=\"https:\/\/www.fambach.net\/wp-content\/uploads\/LogicAnalyzerTop.jpg 600w, https:\/\/www.fambach.net\/wp-content\/uploads\/LogicAnalyzerTop-300x127.jpg 300w\" sizes=\"(max-width: 599px) calc(100vw - 50px), (max-width: 767px) calc(100vw - 70px), (max-width: 991px) 429px, (max-width: 1199px) 637px, 354px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"151\" data-id=\"5072\" src=\"https:\/\/www.fambach.net\/wp-content\/uploads\/LogicAnalyzerBack.jpg\" alt=\"\" class=\"wp-image-5072\"\/><\/figure>\n<\/figure>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-2 is-cropped wp-block-gallery-2 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/www.fambach.net\/en\/?attachment_id=5073\"><img loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"232\" data-id=\"5073\" src=\"https:\/\/www.fambach.net\/wp-content\/uploads\/LogicAnalyzerPins.jpg\" alt=\"\" class=\"wp-image-5073\"\/><\/a><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/www.fambach.net\/en\/?attachment_id=5075\"><img loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"239\" data-id=\"5075\" src=\"https:\/\/www.fambach.net\/wp-content\/uploads\/LogicAnalyzerUSB.jpg\" alt=\"\" class=\"wp-image-5075\"\/><\/a><\/figure>\n<\/figure>\n\n\n\n<p><\/p>\n\n\n\n<h1 class=\"wp-block-heading\">Installation<\/h1>\n\n\n\n<h2 class=\"wp-block-heading\">Sigrok PulseView<\/h2>\n\n\n\n<p>Download: <a href=\"https:\/\/sigrok.org\/wiki\/Main_Page\">https:\/\/sigrok.org\/wiki\/Main_Page<\/a><\/p>\n\n\n\n<p>Download and install software.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Driver<\/h3>\n\n\n\n<p>My clone uses the open-source fx2lafw driver, which can be downloaded from the following link.<\/p>\n\n\n\n<p>Download: <a href=\"https:\/\/sigrok.org\/download\/binary\/sigrok-firmware-fx2lafw\">https:\/\/sigrok.org\/download\/binary\/sigrok-firmware-fx2lafw<\/a><\/p>\n\n\n\n<p>If another driver is needed, further information can be found on the PulseView website.

I bought the first one sometime before 2020 and never got it to work. After that, I ordered the AZ-Delivery version, but that one also had its problems. However, once you know how it's done, the installation is quite simple. I'm unsure why the first attempt didn't work. Now both devices are working and I can dedicate myself to my new series of TTL ICs. I might order a 16-bit version and take a look at it.<\/p>\n\n\n\n<h1 class=\"wp-block-heading\">Related Posts<\/h1>\n\n\n<ul class=\"display-posts-listing\">\n<li class=\"listing-item\"><a class=\"title\" href=\"https:\/\/www.fambach.net\/en\/logic-analyzer-kurz\/\">Logic Analyser (Clone)<\/a><\/li>\n<li class=\"listing-item\"><a class=\"title\" href=\"https:\/\/www.fambach.net\/en\/arduino-esp8266-zusatzplatine-7\/\">Zadig<\/a><\/li>\n<li class=\"listing-item\"><a class=\"title\" href=\"https:\/\/www.fambach.net\/en\/customkeyboard\/\">CustomKeyboard Library<\/a><\/li>\n<li class=\"listing-item\"><a class=\"title\" href=\"https:\/\/www.fambach.net\/en\/codeshorty-serieller-interrupt\/\">CodeShorty: Serial Interrupt<\/a><\/li>\n<li class=\"listing-item\"><a class=\"title\" href=\"https:\/\/www.fambach.net\/en\/raspberry-pi-als-nvr-mit-shinobi\/\">Raspberry Pi as NVR with Shinobi<\/a><\/li>\n<li class=\"listing-item\"><a class=\"title\" href=\"https:\/\/www.fambach.net\/en\/mysd-anpassung-der-arduino-bibliothek\/\">MySD adjustment of the Arduino library<\/a><\/li>\n<li class=\"listing-item\"><a class=\"title\" href=\"https:\/\/www.fambach.net\/en\/debug-ausgaben-im-quellcode\/\">Debug output in source code<\/a><\/li>\n<li class=\"listing-item\"><a class=\"title\" href=\"https:\/\/www.fambach.net\/en\/switchlib\/\">SwitchLib<\/a><\/li>\n<li class=\"listing-item\"><a class=\"title\" href=\"https:\/\/www.fambach.net\/en\/mpv-linux\/\">MPV (Linux)<\/a><\/li>\n<li class=\"listing-item\"><a class=\"title\" href=\"https:\/\/www.fambach.net\/en\/ispy\/\">ISpy<\/a><\/li>\n<\/ul>\n\n\n\n<h1 class=\"wp-block-heading\">Sources<\/h1>\n\n\n\n<p><a href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1509\/1638\/files\/Logic_Analyzer_Datasheet.pdf?104423\">https:\/\/cdn.shopify.com\/s\/files\/1\/1509\/1638\/files\/Logic_Analyzer_Datasheet.pdf?104423<\/a><\/p>\n\n\n\n<p><a href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1509\/1638\/files\/Logic_Analyzer_Pinout.pdf?44545\">https:\/\/cdn.shopify.com\/s\/files\/1\/1509\/1638\/files\/Logic_Analyzer_Pinout.pdf?44545<\/a><\/p>\n\n\n\n<p><a href=\"https:\/\/www.saleae.com\/downloads\">https:\/\/www.saleae.com\/downloads<\/a><\/p>\n\n\n\n<p><a href=\"https:\/\/learn.sparkfun.com\/tutorials\/using-the-usb-logic-analyzer-with-sigrok-pulseview\/all\">https:\/\/learn.sparkfun.com\/tutorials\/using-the-usb-logic-analyzer-with-sigrok-pulseview\/all<\/a><\/p>\n\n\n\n<p class=\"wp-embed-aspect-16-9 wp-has-aspect-ratio\"><a href=\"https:\/\/www.youtube.com\/watch?v=rR5cEFRO9_s\">https:\/\/www.youtube.com\/watch?v=rR5cEFRO9_s<\/a><\/p>\n\n\n\n<p><a href=\"https:\/\/ideas.saleae.com\/f\/changelog\">https:\/\/ideas.saleae.com\/f\/changelog<\/a><\/p>\n\n\n\n<p><a href=\"https:\/\/sigrok.org\/download\/binary\/sigrok-firmware-fx2lafw\">https:\/\/sigrok.org\/download\/binary\/sigrok-firmware-fx2lafw<\/a><\/p>\n\n\n\n<h1 class=\"wp-block-heading\">Log<\/h1>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\"><table><thead><tr><th>Date<\/th><th>Description<\/th><\/tr><\/thead><tbody><tr><td>28.04.2020<\/td><td>Post created, device not recognised.<\/td><\/tr><tr><td>18.05.2024<\/td><td>I replaced the driver with Zadig.
