Reviewing equipment is not my day job and so other priorities come first. Patience will be required by those wanting a review as these are just 'toys' to play with compared to my day job responsibilities. There are never enough hours in a day ;) |

Personally, I don't need a lengthy review. A thumbs up, or thumbs down, along with two sentences; one sentence for pros and one sentence for cons, and I'd be happy. :D Please don't misinterpret my comments, I fully understand you might be busy, and I'm completely happy, if you write something once you feel like it. Thank You, JimmyMz |

OK, I will sort something out this week for you. It will not be a lengthy review but will detail my findings when used on a digital test piece that I have. I also have the Hantek 1025G Function/Data pattern generator that will present the LA with some different data patterns. I really want to get stuck into testing these but alas life has been on the hectic side of busy since purchase. For info I also have a Sysclk-DX en-route to me. That has a lesser sampling frequency capability, but does offer data decoding and two low frequency oscilloscope channels in the one box. A true MSO it isn't but it may be an interesting 16 channel unit all the same. Sysclk-DX Specifications: Two input channels with a maximum analogue sampling rate of 24Msps Analogue Bandwidth 3 MHz Analogue Channels: 2 Input voltage measured: -10V to 10V Input impedance: 1MOhm/30pF Logic I/O Channels :16 Protocols: Channels: 16 Maximum sampling rate: from 1 to 24Msps with 4 trigger levels SPI, I2C, Async, USB, PS/2, SM Bus, Sync Serial, CAN, 1-Wire, Parallel busses as well as Custom Decoder capabilities Utilities: Bus Data Extractors Oscilloscope/Logic Analyzer Bus Decoders PacketPresenter Digital Signal Generator Data Logger Voltmeter Frequency Counter I2C Bus Controller Frequency Generator PWM Controller Pulse Counter Toolbuilder Source Code API Remote Controller http://www.aliexpress.com/item/Free-Shipping-Sysclk-DX-Mixed-Signal-Oscilloscope-and-logic-analyzer-USB-2-probe-P6100-20LA-probes/583945355.html I also own a Link Instruments 200Ms/s MSO-19 that is an 8 Channel MSO with one analogue input. http://www.linkinstruments.com/mso19.htm Its a very clever product but it has only 8 channels in the LA and cost a lot more than the other two LA's. Watch this space. |

I'm another fresh happy [hard to say] owner of this device, so here are my 5 eurocents: Hardware: * + big buffer * + build quality is much higher than expected * + a good FGPA+DDR+USB plaform (more on this later) * - clips quality is poor * - plastic bumpers of the housing produce strong "chinese equipment" smell (thrown away immediately) Software: * + trigger options beyond simple single edge/single pattern * + protocol decoders seems to work * - stucks in "Capturing..." state often (Stop button does nothing, or there is some very big delay?) * - no data save/load function, export only * - waveform render is extremely slow! zoom/scroll operations takes seconds * - using cursors is a bit complicated - right click, select from menu * - no external clocking option (although mentioned in manual, ACLK/BCLK pins present on a connector, but Hantek support had confirmed that it's not possible) I don't expect breakthrought sw updates from manufacturer, but hw part looks pretty powerful, so I'll try some DIY based on it (first - try adapting some 3rd party sw like open source sigrok). I did a quick research already, here are some results: * Both FX2 and FPGA boots to their final states from serial EEPROMs, not from PC (not so handy for experiments, but this can be fixed - disconnect both EEPROMs, switch Spartan to Slave Serial mode) * FX2's fw is pretty dumb, data passes directly to/from FPGA with no sw intervention (slave FIFO mode) * Spartan's JTAG pinout found (so I got access to spartan's pins via boundary scan) * All FX2-Spartan interconnect found * All Spartan-test port interconnect found * Both DRAMs are connected to Spartan's dedicated MCBs * The undocumented USBXI is FX2's USB, 2 Spartan's IOs (triggers?), power/gnd * Test port has two reference voltages (defines treshold voltages) generated by obscured U11,U12,U13. U13 is connected to SpartanIf somebody wants to play with this device, I can post more details. To codeboy2k: Cypress FX2 gives both simplicity and high throughput (20+ MBytes/s can be reached with a few lines of code, most of the hard work is done by hw). AFAIK comparable Atmel chips (ones with USB 2.0 HS ports) are ARM9s suitable for Linux, with much more complex programming. |

They are currently in a process of standardizing/modularizing logic sniffer firmware codebase so it can be reused on all of the supported devices. http://sourceforge.net/mailarchive/forum.php?thread_name=51923CBA.4000308%40ciellt.se&forum_name=sigrok-devel |
