SCPI on Mac

Some more days passed and some more finishing touches added to my MacSCPI app. It is entirely dependent on hooking the device via the USBTMC driver, but it works fine and is stable: I had some problems with buffer padding and the output it is still not 100% gibberish–free , but I assume I have to play with …


USBTMC driver for Mac

After some head banging, I finally managed to send SCPI commands from my Mac to my Agilent (Keysight) DSOX2002A. I’ve worked on this since december last year. Almost a year, but I did not spent a sustained amount of effort. I did it just during my free time. I still have a day job that …


Bye, bye Vacation !

I took a break for almost two months and it was so good ! Away from any disturbance, just us, the Sea and some books. The first couple of weeks slipped away almost unnoticed. There’s something special about Mediterranean… exerts an irresistible charm. Laying on that sea’s shore I can just close my eyes and …


Rigol Spectrum Analyzer !

I’ve kept drooling for this for several years. Today I finally got it ! Moreover, it seems it is fully-option enabled, which is kinda weird because I haven’t ordered for such. However, here it is: the Rigol DSA 815 TG Spectrum Analyzer with tracking generator. This will enhance my lab’s capabilities in RF electronics and …


C#, SCPI and Keysight (Agilent) DSO-X 2002A

This post is a relic. The initial draft dates back in January 19, 2013. And was left as draft ever since. Past couple of days I was busy — among other things — learning a new programming language, C#. 🙂 Ok, here’s the deal: my scope (KeysightAgilent DSO-X 2002A) is SCPI–compliant device. If you remember, the reason behind …


…and the order from DigiKey

Ok. Today was THE mail day. I’ve received both my electronic parts orders, the one from RF Parts and the one from DigiKey, that I placed several weeks ago (but had some issues with a couple of backordered items). Ta–Da ! This is it: A lot of bags and goodies. Not to mention the pleasure of sorting …


My first order from RF Parts…

I was looking for a RF power module for my APRS beacon project and stumbled upon RF Parts. They are somehow of a niche–oriented online electronic part retailers, specialised on RF and — it seems — mostly on Ham Radio RF parts. I placed my order for two Mitsubishi power RF MOSFET Amplifier Modules and the package …


LTSpice Parameter Sweep

While designing/ working on my APRS project, I used LTSpice IV for some simulations. For those that don’t know, LTspice IV is a high performance SPICE simulator, schematic capture and waveform viewer from Linear Technology. It is a freeware and can be downloaded from this link. Versions for my both platforms exist, Win 7.0 and Mac. …


Red and Green

This will be a very short post. And only for the blog. I have a sweet spot (call it idiosyncrasy) for stationery. I mean, some people do heroin, some do alcohol, some do Oprah. I am addicted to stationery. Put me in a stationery shop — you can leave me there all day (give or take), …


144.8 Mhz TX for APRS (3)

This is a quick update post. The road I took with this little project is slowly getting to a dead end due to what it seems to be a lack of available crystals for 144.8 (like 48.26 or 28.96 MHz, for using the third or fifth harmonic). I believe that, currently, all APRS modules are …
