There is no typing in of code required, just download and have the Arduino IDE send it to the Arduino. There are actually two varieties - one runs on the Arduino alone and interfaces to the PC (or

Hi Wayne, There is very little connection between this project and a Rpi. Noobs is the basic how to set up an operating system for the Rpi, either Raspian, a version of the main

Hi All, Let me say at the outset that I am new to this group and New to Raspberry Pi. As I understand it a Noob is a prewritten file of code that can be loaded into a Pi to control your project. So

Aw darn it... forgot once again to say send board requests to my direct e-mail n5ib (at) juno (dot) com -------snip-------- The ones marked * have had 3 or fewer requests, so may not yet be enough to

The test run of Experimenter Boards arrived a few days ago and I built one up. There were a couple of minor layout issues that I've corrected. Proved that the trial run was a good idea - hi -

Glad it's working! Was that trace on the bottom side of the PHSNA that grounds D2 actually cut, or was it a board defect? That amplitude behavior is not normal, in particular the big dip at 11 MHz.

Nick and Jim: Good news, guys!. Adding the jumper to the DDS module to shift from parallel to serial mode did the trick. The DDS is now putting out frequencies and successfully doing sweeps. Oddly

That's fine - if you only ever go above 35MHz. I'd say it complements the AD9850 / 9851, rather than replaces it: put them together for increased spectrum coverage. Personally, for a Network

I was thinking of how this chip could be used considering that the output is square wave and hence full of harmonics. Wondering if I could do with only a single generator ( vs using two, the second at

How about the ADF4351? It goes from 35MHz to 4.4 GHz. I got a board from Aliexpress and wrote some code to sweep it in any range of 256 steps of any step size. I could contribute that. Azzy

If you want higher frequencies, you need a different generator - or redesign the current one. The AD9851 typically runs at 180MHz, and the "cleanest" sine waves are under 60MHz. Due to the wonders of

Sorry to have been absent for a spell... have been preparing an exhibit on behalf of our local club for a Maker Faire at the public library this weekend. Refer to Fig 18 of the AD-9851 datasheet. To

I had downloaded from the files section the Type I DDS schematic which unfortunately is in Chinese. I have studied it with the help of the AD9851 datasheet and labeled the jumpers/connectors in

Hello, This email message is a notification to let you know that a file has been uploaded to the Files area of the PHSNA group. File : /DDS I schematic labeled.pdf Uploaded by : eb4apl

It's been a while since I thought about those jumpers. I looked at my early notes on putting my unit together. I started with an AD9850 type board, not sure if it was what we call "type I" or "type

DuWayne, You have my interest here. I checked out your blog and will also look at the driver source code. If you want to contact me at my email address, it is N1VC (at) yahoo (dot) com. Thanks, Vince

Nick: Thanks very much for the note. The short answer to the questions you posed in your note is that I have done everything you suggested down to the paragraph discussing the programming jumpers.

It's sure frustrating when something just doesn't want to work. I've got one going right now that's hung up, but I'll get it off dead center soon. (Not PHSNA related.) I'm trying to remember all the

You could use the existing PHSNA and bring out A4 A5 5v and ground to an external 5351 board. Then change the existing PHSNA code to control the 5351 and use the same graphing function. I have an

John, Thanks for the reply. This is worth looking into. Vince
