User questions & answers

Question:	Anyone get this error msg? the application was unable to start correctly (0xc000007b). click ok to close the application
Answer:	I was experiencing the same error with Sigrok's PulseView x64 and ZaDiag x64 not properly starting, with the OS tossing a 0xc000007b error dialog every time I tried to launch either app. As with the other answerer, the 32bit version would install and would start, but not work correctly with this LA. I ended up giggling my way to success in determining that I didn't have the right .net libs yet installed on this box (a fresh install of Win10 x64). This site (www.techjunkie.com/0xc00007b/) pointed me to the right download needed, in the section 'HOW TO FIX ‘THE APPLICATION WAS UNABLE TO START CORRECTLY 0XC00007B’ ERRORS' - I did the Microsoft Visual C++ 'x64' recommendation (the 'x64 version' of the MS Visual C redistributable). After this, I was able to install and successfully launch the x64 versions of both the PulseView and ZaDiag apps. Currently, I am still struggling with getting PulseView x64 to work with this LA correctly, even after using ZaDiag x64 to change the driver to the default one it offers when it launches. Still working that and will update once I get it. For now, I reverted to using Saleae's Logic 1.2.29 Beta app (available from heresupport.saleae.com/logic-software/latest-beta-release - link good as of 10Jun19). To get Saleae's app to work with it, I had to repeatedly uninstall the device (including deleting the drivers) from the MMC Device Manager snap-in until, when searching for new plug and play hardware, it shows up as 'unknown device'. Once to that point, running the Saleae app should result in it seeing the driverless device with the HW IDs it is looking for and will assimilate it and install the drivers for it, and instantiate it as a 'USB Serial Bus controller|Saleae Logic USB Logic Analyzer', enabling this LA to be used from the Saleae Logic 1.2.29 app (images: i.imgur.com/J60jm8A.png & https://i.imgur.com/NA0MabE.png). As indicated above, once I get this LA to work with the 64-bit version of PulseView/ZaDiag properly, I will update this answer with additional details. Until then, take care. -t
Question:	Can you write I2C commands or is this only aquiring the commands
Answer:	I'm using the logic analyzer to show and decode logic only... and a Bus Pirate V3.6A to control the I2C bus. Sigrok and Putty for the Windows PC side of things. Nice combination!
Question:	What protocols does this support
Answer:	This product does not natively support any protocols. The protocol decoding is done by the host software. Check out the feature sets for PulseView and Saleae Logic software.
Question:	What software is required for Mac or PC
Answer:	https://support.saleae.com/hc/en-us/articles/115005972023-Saleae-Logic-Beta-Software now with real time (ish) display

User questions & answers

Question:	How fast is the sampling when doing continous capture? IS it usb3 compatable
Answer:	It is a USB 2.0 Device only from my experience. Also, its a 200Mhz max sample rate with all 16 channel enabled. The less channels enabled, the faster it can sample.
Question:	Is the unit comparable with the Saleae software
Answer:	Don’t know, but GNUPlot is free and an excellent software.
Question:	does this have an ext trigger input/output
Answer:	We provide enough memory.Not need external trigger. Internal trigger only
Question:	Does it work
Answer:	It works amazingly well especially considering the cost. The software is somewhat basic but includes a number of decoders that you have to pay big money for on other logic analyzers. I have never once had a failure of any kind using it. Even the PWM output channels are dead on when probed on the oscilloscope. Also the probe leads are some of the best quality silicone that I have ever seen on one of these. Give it a try you will not be disappointed.

Product description

The EspoTek Labrador is a USB Device that turns any PC (Windows/Mac/Linux), Raspberry Pi or Android device into a full electronics lab with oscilloscope and more. The software interface was designed from the ground-up to be intuitive for students and makers, while retaining some of the more complex features than experienced engineers can make use of. Best of all, the hardware and software is 100% open source - all code and design files are publicly available on GitHub. All Labrador users have access to the best support possible: a direct line to the product developer. If you have any issues or suggestions, simply send a question to the EspoTek Amazon Storefront and I’ll do what I can to help.

• Oscilloscope (2 channel, 750ksps)
• Arbitrary Waveform Generator (2 channel, 1MSPS per channel)
• Power Supply (4.5 to 15V, 0.75W max output, with closed-loop feedback)
• Logic Analyzer (2 channel, 3MSPS per channel, with serial decoding)
• Multimeter (V/I/R/C)

User questions & answers

Question:	What is the maximum input voltage for the oscilloscope
Answer:	The scope has an input voltage range of -20V to +20v. If you need more, the device is pretty simple to modify. Just solder on an additional resistor in parallel with R3 and R4 and then rebuild the software with the R3 and R4 variable changed. All the schematics and source code are online and freely available, and I'm happy to help you out if you get stuck modifying your device. ~Chris
Question:	How connect to android phone, otg cable required? Does it power via usb
Answer:	To connect to and Android phone, you will need an OTG-compatible device as well as an OTG cable. You do not need any additional power inputs.
Question:	so is this a 0.750 Mhz then
Answer:	Hey, not exactly sure what you're asking by this question, but the oscilloscope samples at 0.75 MSa/s. So not as fast as a full size $1000 scope from Tektronix or Rigol, but more than enough for most hobby projects. ~Chris
Question:	Hi admin, it's cool you actually answer questions. mine are: 1) how high a frequency can this stably measure? 2) how short a pulse can it measure
Answer:	I've currently spent the last 5 years of my life working on this project (and still going); the least I can do is answer a few questions! Do other people not do this? The scope samples at 750ksps, so theoretically it can measure a 375kHz sin wave. In practice, though, anything more than 100kHz is not really stable or recognisable. For the pulse, you could use the digital inputs of the scope that measure at 3Msps. You'd need at least 3 samples (low, high, then low again) to guarantee that the pulse was detected correctly, so that gives a minimum pulse length of 1us.

User questions & answers

Question:	difference between type 1 and type 2 models
Answer:	My understanding type one does NOT have internal power source (battery), whereas type two has the internal batter. You should also know that there are two different battery sizes. I chose the smaller, as I don't expect to be running it for more than 2 hours (per spec) at a crack anyway (that is, without plugging it in somewhere). And, yes, the calibration loads are included in both.

User questions & answers

Question:	is the tracking generator a trial period or permamently loaded
Answer:	When I ordered mine about two months ago, Siglent was offering the TG bundled with the SSA-3201x, and when I received my unit, all the extra functions were activated for a trial period, but the permanent license for the TG was included....a long-winded way of saying it was permanently loaded
Question:	The ssa3000x manual shows features that seem to be part of the advanced measurement opt. how do i know what features are included in the basic sa
Answer:	Everything except those options are standard and included with the SS3021X-TG. The manual will talk about the options when discussing the use of certain functions and notifies the user that these options are necessary for a given task. That's just my opinion. The tracking generator is of course standard, but SWR measurement, and freq. range increase,etc you must buy. hope this helps?
Question:	What other options are available and what is the cost
Answer:	Check with Siglent I believe one is a return loss bridge, dont remember the other. Seems like they were > $500.
Question:	The title on top of the sa says "9khz to 1ghz" and the specs just bellow go trough 2.1ghz. is it a mistake?. all 3021x go to 2.1ghz so yours don't
Answer:	U are right. It goes to 2.1 GHz not 1Ghz. There are only 2 models, both of which are hardware identical. Not sure why the advertiser chooses not to correct it. Remember also you can unlock the 3.2GHz capability in a 2.1GHz model.
