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 […]
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 […]
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 […]
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 […]
More work today and yesterday on this project. Still locking on 144 MHz, but this is normal, the crystal I used is a 48 MHz overtoned, working on the third harmonic in this case, thus spot on 144.0 MHz: I managed to clean the output, at the expense of transmitted power. I used a 7-pole 2m bandpass […]
Been busy at work lately, but still had some time for myself. Latest idea: a low-cost APRS beacon, done with a classical 144.8 Mhz TX and a μController. AX.25 on air. Automatically. So these days I’ve been busy making this: Winding coils, soldering, measuring. Fun. The frequency is remarkable stable, given the rudimentary nature of this. For example, […]
December again, another year passed. Traditionally, this is a month when I am taking a long break. But I was up to something in the past days and I wanted to share. I have created a driver for my KeysightAgilent DSO-X 2002A oscilloscope. Maybe not a big deal, but huge for me because this is […]
Keysight’sAgilent’s InfiniiVision 2000 X-Series Oscilloscopes Programmer’s Guide is highly recommended for anyone interested in remotely controlling KeysightAgilent InfiniiVision 2000 X-Series Oscilloscopes. Via back USB slot. For example: Unfortunately, the [remote] control is limited only to Win PCs. AFAIK. Have to write a review soon about the cool KeysightAgilent Connection Expert, the client app installed together with the KeysightAgilent […]
I just got it few days ago, a superb brand new Agilent 2002A Digital Storage Oscilloscope. Needless to say that I am absolutely thrilled by this 2G/s 70Mhz baby. It is a perfect addition for my electronics projects. Now I am playing with it, much to discover in the documentation. It comes with a CD […]
