Sigrok Compatible ZeroPlus Logic Cube LAP-C USB Logic Analyzers Support up to 32 Channels, 75 MHz Bandwidth

Back in 2015, I discovered USB123 USBee AX PRO, an ultra cheap logic analyzer (now $5 shipped) with 8 channels, and up to 24 MHz. I purchased one at the time, and successfully tested it with Sigrok & Pulseview open source tools that now work in Linux, Windows, Mac OS, FreeBSD, Android, and several other operating systems. As I read through my list of RSS feeds today, I noticed Peter Scargill had tested ZeroPlus Logic Cube Lap-C 322000 logic analyzer also connected to your PC via USB, but with better specifications including 32-channels, and 75 MHz. Peter used the company’s Windows software (ZEROPLUS Logic Analyzer LAP-C_Standard_V3.14.03), but a quick search confirmed ZeroPlus Logic Cube Lap-C family is supported by Sigrok. LAP-C 322000 is the top model from the family with the following hardware specifications: Sample Rate – Internal clock (timing mode): 100Hz~200MHz; external clock (state mode): 100MHz Bandwidth – 75MHz Working Range – -6V~+6V Accuracy – ±0.1V Memory – 64Mbit, …

BayLibre ACME Cape for BeagleBone Black Measures Power and Temperature with Sigrok

Sigrok open source signal analysis software suite had a major release last week-end with libsigrok 0.4.0, libsigrokdecode 0.4.0, sigrok-cli 0.6.0, and PulseView 0.3.0. The new version added numerous bug fixes for supported hardware such as UNI-T UT61E digital multimeter or USBee AX Pro logic analyzer, and added support for several logic analyzers, oscilloscopes, multimeters, programmable power supplies, an electronic load, an LCR meter, a scale, and one BeagleBone Black cape, namely BayLibre ACME. The ACME initiative was launched in order to get rid of the limitations of proprietary solutions, and provide an open source hardware and software multi-channel power and temperature measurements solution to the community. BayLibre ACME cape supports up to 8 probes to measure VBUS (0 to +36V), VSHUNT ( 2.5uV up to 81.92mV), CURRENT AND POWER. Three current / power probes have been developed with all featuring TI INA226 for the ADC conversion: ACME HE10 Power Probe 6-pin HE10 header with up to 6A max current, 13mΩ …

Using USB123 USBee AX Pro $5 USB Logic Analyzer with PulseView in Linux

I recently wrote about an ultra low cost USB logic analyzer called USB123 USBee AX Pro, which I bought for $9.58 on DX, but I was later informed it also goes for $5.44 on Aliexpress including free shipping to most countries, and a few dollars extra for shipping to some other countries. Nevertheless, I’ve now received it, and instead of testing it with a closed source (and cracked) Windows software, I installed and ran PulseView open source graphical interface for sigrok, which I previously tested on UNI-T UT61E digital multimeter. The package includes USBee AX PRO mini logic analyzer, 10 dupont wires for 8 channels (digital only) and 2 ground pins, as well as a mini USB to USB cable for connection to a computer. The instructions to use the logic analyzer can be found on Sigrok Wiki. My computer runs Ubuntu 14.04, but Sigrok and PulseView can also be installed on other Linux distributions, as well as Windows, Mac …

USB123 USBee AX PRO is a $10 USB Logic Analyzer Clone Compatible with Sigrok

A few months ago, I wrote about low cost logic analyzers selling for $75 and up, but yesterday, I stumbled upon an even cheaper, and admittedly lower end, logic analyzer called USB123 USBee AX PRO, allegedly a clone of the original USBee AX PRO minus the analog inputs, that sells for $9.99 on Dealextreme. [Update: It can also be bought for $5.60 on Aliexpress including shipping to most countries] USBee AX PRO specifications: Sampling rate – 24Msps Sample rate – 24MHz @ 8 channels Input voltage range: 0~5V Digital channel: 8 Low input voltage: < 0.8V; High input voltage: >1.4V Supported Protocols – SPI, IIC, UART, SMBus, I2S, CAN, Parallel, Custom, Search, Async, 1-Wite, PS/2 Dimensions – 5.4 cm x 2.7 cm x 1.8 cm Weight – 60 grams The tool ships with 10 Dupont cables and a USB cable to transfer data to your PC. DealExtreme also provides CDROM image with a user’s manual and utilities such as USBee …

Sigrok and Pulseview in Ubuntu 14.04 with UNI-T UT61E Digital Multimeter

A couple of months ago, I received a new digital multimeter UNI-T UT61E that can send data to a computer via a serial cable, and allows you draw some nice charts. I’ve already done that in Windows 7 with the provided tools, and reported on the power consumption of some Chinese Android TV boxes. However, since I use Ubuntu 14.04 as my main operating system, Linux based tools would be more convenient, and open source sigrok-cli command line client and its graphical interface pulseview are supposed to support UT61E DMM, so I had to give it a try. A Quick Look at UNI-T UT61 Digital Multimeter Before going into Sigrok, I’ll quickly show what the multimeter received from DealExtreme . It took longer than expected to ship because of of  included 9V battery, and at the first shipping attempt it was returned to DX, but after 8 weeks or so, I finally received the package. The multimeter came with test …
