The software is based upon Sigrok, which is the front end used to drive many of the Cypress based tools. SoftwareĭSLogic’s software is DSView, currently at version v0.93 on their website. The DVIULC6 is an array of clamping diodes, often found in HDMI or Ethernet interfaces. Inputs to the DSLogic are protected by a ST DVIULC6-4SC6 “ESD protection device”. At speeds like this, programmable logic is the way to go. Most of the internal logic is handled by a Xilinx Spartan 6 FPGA. At 200 MHz, the DSLogic drops down to 8 channels, at 400 MHz, it’s a 4 channel device. HardwareĭSLogic’s specs are rather nice – 400 MHz max sampling rate, 16 channels, and 256 Megabit on-board memory. Of course you can’t do all of this at once. Considering the cost of quality clips from Tektronix, (several dollars each), I can’t complain too much. I can understand Dreamsource Labs’ decision to go with the cheaper clips – they do work, they’re just a bit harder to work with. The plastic parts of these clips tend to fall apart (in fact, a few had all ready fallen apart in shipping), but are easy to snap back together. They’re the cheap kind that consist of a. The only disappointment in the package were the included test clips. While using coax doubles the connections, it’s vitally important to have proper grounding and signal integrity when measuring digital signals at speeds up to 400 MHz. Mine was an updated version, in which all the grounds are ganged at a small PCB on the connector end. There were some issues with this cable assembly breaking in the early versions of the tool. Each of the data lines is actually a superfine coaxial cable. The probe header itself is quite something. One end allows the probes to pop on to their. The unit itself is a flat (9mm tall) aluminum box similar to the Saleae logic in construction. The DSLogic ships in a fine multi-layer cardboard box which I marveled at for about 0.5 seconds before tearing it up to get at the goods. In this review we’re focusing on the logic analyzer portion of the tool. These days both the DSLogic and the oscilloscope extension are available at The Hackaday Store. I think it’s safe to say that they did well, raising $111,497 USD, more than 10 times their initial goal of $10,000 USD. DSLogic designed by DreamSource Labs, can be thought of as an open source evolution of the original Saleae device.ĭSLogic appeared in 2013 as a Kickstarter campaign for an open source logic analyzer with an optional oscilloscope extension.
They also inspired an army of clone devices based upon the same Cypress Semiconductor parts. Low cost, high-speed, and easy to use – these devices were perfect. There have been a number of USB based logic analyzers introduced in recent years, but they didn’t really catch on until Saleae released their “Logic” line of devices. You can see things you’d never see with another tool – like a data bus slowly settling out after the read or write strobe. Once setup though, logic analyzers were great at finding bugs. If not, you were stuck typing your signal names into the front panel keyboard.

Setting them up was a pain – if you were lucky, the analyzer had a PC keyboard interface. The logic analyzer came out when all else failed, when even a four channel scope wasn’t enough to figure out your problems. Logic connections were made through pods, with hundreds of leads weaving their way back to the test equipment. For many of us, the name invokes mental images of large HP and Tektronix iron with real CRT screens. Logic analyzers historically have been the heavy artillery in an engineer’s arsenal.
