There are quite a few good resources already out there for the NanoVNA, but I’ve seen a few people mention that the prospect of updating the firmware is daunting. Indeed it is if you try to build it from scratch as the tutorials that I’ve seen have you do. However, that’s not really necessary for… Read More Updating the NanoVNA Firmware
As regular readers are well aware, my main PC runs Linux Mint, and has for many years. I do run a Windows 10 PC as well, in order to build code for that platform as well as to play games, but it’s my preference to do nearly all of my work on my Linux box.… Read More Some PC Software for NanoVNA
Anyone following Hackaday and other hobby electronics blogs/YouTube channels has probably noticed the buzz around the NanoVNA lately. Admittedly I don’t know a lot about it, other than the fact that the design and firmware is open source and now a bunch of Chinese manufacturers have started making it and that you can now get… Read More Onto the NanoVNA Bandwagon
OpenTechLab If you’ve been reading my blog for any amount of time, you’ve probably observed that I’m a big fan of all things open source, especially on the hardware side of things. One area where OSHW seems to be lagging a bit is in the test & measurement department, so it was a very pleasant… Read More Wideband Transmission #10
I know that quite a few of you are, like me, owners of the Rigol DSA815-TG. It’s been a reliable workhorse in my lab since I’ve acquired it, but the one thing I believe that I’ve wanted to most from it is a an RBW minimum of 10 Hz instead of the specified 100 Hz.… Read More Nice DSA815 Upgrade
Arduino in the Cloud I saw a recent post on the Make blog about the new cloud ecosystem for Arduino which has been dubbed Arduino Create. Since this will most likely be the future of Arduino, it seemed wise to get an early look at the platform. It includes quite a few features, but the… Read More Wideband Transmission #9
Back when I was working at Tektronix (wow, this summer it’s been 10 years since I graduated with a AAS in EET and started at Tek), they had a one-time program where an employee could purchase a new TDS1000/2000 series oscilloscope for half of the list price. This was back in the day before the… Read More TDS1012 LED Backlight Retrofit
Needing to upgrade my spectrum analysis capability, I recently sold my trusty boatanchor HP 8558B to help finance a portion of a new Rigol DSA815-TG spectrum analyzer. Last week I was able to order the 815, and today it finally showed up on my doorstep. I first came across the 815 last year, at the… Read More Quick Impressions of the Rigol DSA815-TG
Yes, a belated Happy New Year greetings! It’s hard to believe that 2013 is already well under way. I figured it was about time to give you a quick update on what’s going on in the shack right now. First up is the discrete component grabber receiver for 14.141 MHz that I prototyped to be… Read More HNY
