|An update on RF Explorer WSUB3G||Ariel Rocholl||4/13/12 2:57 AM|
After many months of hard work, we got a candidate design for final production of the new wideband model covering 15 to 2700MHz, labeled as WSUB3G.
It will be available as an Expansion Module RFEMWSUB3G, so you can plug it in any RF Explorer base unit, and will be available from SeeedStudio and distributors.
Can you plug a RFEMWSUB3G module on any base unit model? Yes. Some combinations
may make more sense than others, but functionality will be available in
whatever combination you need it to be used. So can you plug a RFEMWSUB3G into
a 433M model? Sure. And what about a 2.4G base unit? You bet. So there is a
natural upgrade path no matter which RF Explorer version you are using today or
planning to use tomorrow.
RF Explorer 3G Combo will be the highest end model, well suited for the Pro TV/Media/Audio user with a WSUB1G base unit and
a RFEMWSUB3G expansion module already assembled. This is convenient as the
WSUB1G model exhibits slightly better sensitivity and sweep speed in the UHF
range of major interest of this business area. In this way you can order and
use a WSUB1G device today and expand it later with RFEMWSUB3G, or order it as a
RF Explorer 3G in one single order, whatever is better for your needs. Price
will be the same one way or another.
Any question, let me know anytime.

Awesome News! I own a WSUB1G, and I love it. I'll be placing my order for the expansion module as soon as it is available. Great job.

This is great news about the RFEMWSUB3G expansion module. I am looking forward to installing one into my WSUB1G. I noticed that this will require me to do a firmware update (currently I have v1.08) and from reading the update instructions it appears I will need a Windows computer to do this. It should not be a huge problem for me to borrow a Windows PC to update the firmware, but it would be much more convenient if I could do the firmware update from a Mac. Is there any plan to make a Mac version of the RFExplorer Firmware Update Loader tool?

A Mac version for the Firmware update tool is on the plans, as well as one for Linux. I do not have an ETA for it yet, but I am sensitive on how important is for many of you.
In the meantime you can use either Parallel in your Mac or grab a Windows PC for this specific step.

WSUB3G module production process is progressing well but slower than we would like. We do not have a firm date on when they will be available, but hopefully will be a matter of weeks.
To help a bit on the many users who are waiting to get one, I can offer some boards from my lab. I have two spare at the moment and can have another 2 or 3 by next week. These boards have been fully tested and calibrated, can be delivered worldwide for $90 but don't include antenna or CNC top cover, so I would suggest only to interested users who already have an expansion daughter board and gets the WSUB3G as a replacement. In this way, the CNC top cover and antenna from the installed board can be reused.
If you are interested, send me an email to rfexplorer (at) arocholl.com with subject "WSUB3G Beta board", I will serve them in a first-in, first-out basis.

All available modules have been reserved already.

A quick notice for all WSUB3G Beta users:
There is a small HW difference between Beta and final boards, and it is a DC blocking capacitor the beta board doesn’t have. In the Beta boards, the power limiter diode is directly connected to the SMA port, whereas in the final board there is an extra 220pF capacitor. Other than that, your board has 100% the same components than the final HW. There are also some minor variations in the PCB, needed for mass automatic assembly process when compared to the manual process I used for the beta boards.
From performance perspective there is no difference at all, except if you expect to deal with your beta WSUB3G directly into a signal in a circuit where there is DC component, in that case you should use a DC block adapter or a specific cable with DC block.
All the final beta boards are delivered calibrated, with an advanced process we put in place in the product line. However, beta boards were not delivered calibrated. You should see an improvement in accuracy, particularly with DSP=Filter mode, when the board is calibrated, so you are suggested to calibrate it using the firmware v1.09 if you have access to a reliable signal source.
Thanks Ken Camuccio for pointing out the differences between Beta and Final boards were not properly documented.

Thanks for this information regarding the Beta vs. final boards. So are the 50 units that SeeedStudio are going to offer at a 20% discount the final boards or are these Beta boards?
|Re: An update on RF Explorer WSUB3G||Ariel Rocholl||9/9/12 2:05 PM|
There are no Beta boards left, all units with and without discount are final.
Thanks for checking,
