Difficult extenders to find. A quality product.

For Extender/Riser boards for 5345A & similar testgear

Excellent service for a product not available any where else. Extremely satisfied with these quality products.

Hi Gordon, thanks for the feedback & glad you liked them.

Worked as described

For 10MHz OCXO Frequency Standard Module or Kit

Bought 2 boards populated with everything except the OCXO. I fitted my Bliley OCXOs and the PCBs work well. Shipping was fast, and the packaging was good. Overall very happy with my oscillators. The adjustment is very sensitive, perhaps consider a larger number of turns trimmer pot for more precise adjustment.

EDIT: Thanks, I didn't even look, just assumed I had Rev C. You are correct of course, these resistors on Rev D allow me to solve the problem completely. As you correctly point out, most references will want around 2.5V, so I will probably change my pot to a 10K or 20K pot instead of the 50K pot. This also increases the number of turns per Hertz. Please note: I am being really, really picky here, mine is tuned to within 10 millihertz straight out of the packet.

Glad they are working out for you & thanks for the feedback. We will give your suggestion some consideration, for the next revision of the PCB.

Some thoughts:
- I believe you have the latest Rev_D of the PCB
- In this rev, you can get more sensitivity by replacing R1&R3 with higher value resistors. Ideally, they should have the same value, but that will depend a lot on whether the Vfc for your OCXO is close-ish to 2.5V (or nearer one of the extremes) They are in series with the POT and by increasing their values you can effectively increase the adjustment resolution, by reducing/narrowing the adjustment range. I will also email you the latest schematic directly. (let me know via PM if you need more info on this)
- FYI: In my experience with these OCXOs, including the Bliley, the adjustment sensitivity is sufficent to 'tune' within the operation range of this class of OCXO.

UPDATE: I just checked and it looks like there are pots with more turns & the same footprint available. I will order some in to evaluate with a view to offering them and an upgrade option. So not need to wait for a new PCB revision :)
Existing users, can simply desolder & replace the existing one, if required.

Great little module, perfect for prototyping

For SendIR, advanced Infrared emitter module (IR)

While you could definitely embed this in your end-project; I plan on using it for speeding up prototyping and to sort of remove a some human error. It is well built and documented. Looking forward to ReceiveIR.
Shipping to USA was fast.

Hi Josh

Many thanks for the kind words...

FYI: "ReceiveIR" is already available....but called "DetectIR" and can be configured with many IR receiver options.
(Unfortunately, it is currently only listed on our own website. When I get some spare time I will also list on Tindie along with our wider range of IR modules)

There ia also another "RecieveIR" module available, called A.IR Shield Rx. This is a dedicated shield for AnalysIR and plugs directly into platforms such as UNO or breadboards. However it can also be used for other purposes and features both a standard IR receiver & IR Learner in one very compact module. Allows signal recording & Carrier frequency measurement. Again only available via our website.

I reallly must get more of these IR modules listed on Tindie.....
