For those of you with an ADALM Pluto SDR, here's a 70 MHz - 6 GHz spectrum analyser & tracking generator:



Looks very interesting. Anyone played with this software?

Cheers,
David

Both the original nanoVNA and the V2 fit perfect in the 100x60x25mm? box you can find very cheap on eBay. Example: 5 for 4 Euro

My plastic manipulation skill are not perfect but the unit is well protected and at such a price per box its no problem if you destroy one.
Just make a hole in the click in cover and some holes in the side for USB and SMA. As there is no battery no need to expose the switch.

The linked eBay auction description says 5pcs for $4.00.
It's not each box, but each order of 5 pieces.

For any of you out there with a nanovna-h. I have just done this storage case for 3d printing

I am working on a taller case to add a 2nd tray for cables
The tolerances are tight. depending on your printer you may have to do a little light sanding for the lid to fit nice as it can be a tight fit.

Yes I believe it is a real H4. I just got it, a couple of weeks ago from R&L.
Here's the version info in the unit.

Version: 0.4.5-7-g57d62f2
Build Time: Jan 1 2020 17:27:30
Kernel 4.0.0
Arch. ARMv7E-M core variant: Cortex-M4F
Port Info Advanced kernel mode
Platform: STM32F303xC Analog & DSP

Here is the info on the label on the back cover of the unit.

Frequency:
50K-300MHZ
300M-900MHz
0.9G-1.5GHz
Power:5V USB (1A Max)
HW version: 4.2
SN: H4-200109xx

Hope this info helps.

forgot to remove the v2 of the subject its for the normal nanovan not the new v2

just a little project im playing with on the 3d printer. new storage case? for my nano.
?once im happy will put the files on thingiverse the lid is printing at moment
at moment its 2 tier. may poss? make a 3 tier version as well with large open tray for test leads.

Hi Erik
Very interesting to see the NanoVNA-QT software accept Touchstone files for calibration standards and it has both port 1 and port 2 reflection calibration and apparent for different genders. I anticipate the Thru then is a s2p file. This is a big step forward for the NanoVNA V2 compared to NanoVNA
Kind regards
Kurt

There are three options.
The V2 comes with its own PC SW derived from the Xana vna.
Next the best known option is nanoVNA saver as it was extended to be able to control the V2 And I have made Tapr-VNA also V2 compatible

Thanks Erik,
You anticipated my question regarding firmware upgrade. Hopefully Gabriel will continue her involvement on the firmware front. Too bad Gabriel didn't follow the NanoVNA-F's use of a virtual disk to perform firmware upgrades.

I don't mind DIY projects that don't involve smd soldering. I suspect a lot of buyers will do like you and build their own cases (3D printed or hand crafted),and operate the SAA-2 connected to a PC without a battery. The cost of cables and calibration standards to 3 GHz probably explains why the distributor decided not to include them. If the buyer purchases cheap aftermarket cables and standards and they don't perform as expected, the SAA-2 distributor can't be blamed.

NanoVNA saver basically behaves identical when controlling V1 or V2. At least during a short test
Tapr-VNA also behaves identical
The Xana derived SW works well and has to be used if you want to upgrade the firmware without ST-Link or similar.

edy555, the original NanoVNA designer, quietly shared a photo of his NanoVNA2 PCB on Twitter without any additional details (see attachment).

Erik can you tell me what software you are using with the SAA-2 and how well the software works compared to using the NanoVNA?

Thanks,

Can you send a screen shot of your " badly twitching display " ?

5 pieces for $3.98 each is no 4 Euro !

If a remember correctly the BOM cost is $10.
I suspect that most people would gladly pay a few bucks more for a full
package.
Sourcing batteries from China is a hassle (shipping restrictions) and
finding a reliable
source for good quality adapters and cables is a gamble. So far 80% of the
cables or
connectors that I ordered on AliExpress were junk or fake.

With time, when others start to manufacture clones, they will be forced to
provide a full kit
at the same price point.

Looks great, Erik.
Thanks for sharing.?
It's unfortunate that people would rather complain than read the designer's posts about attempting to meet a certain price point.?
This release is a great starting point for early adopters and it can only get better.

Our next Reddit Net on Brandmeister TG 98003 is going to be about the NanoVNA.

Full info here:

I'm sure we will have some complicated questions so it would be cool if some experts showed up. Hope to see you there!

Hi Kurt,
I purchased the battery from a local market. Have a look.
The Tindie seller hasnt shipped the package yet. Meanwhile I shall keep all things ready.

Its available on Tindie. Just order two from there instead of going through the SZ seller I was planning earlier.
