I spent most of the day playing around, going through menus and trying various features. I am extremely impressed. It's a tour de force of RF design.

In order I'd like to see:

An MCU with more memory e.g. STM32F303 to allow easily adding features, storage, etc. This is, in my view, the most important thing. It would allow better RBW filters and many other things such as a menu tree display option.

A single input port which is switched between ranges electronically.

A tracking generator

An electronic switch for turning a diode noise source on and off a la 8970B for automated NF measurements using an external voltage source of up to 24 volts as required by a 346B.

The option of either a 2.8" or a 4" screen. Both are desirable in different use cases. I'd probably buy both versions if the only difference was the screen size.

Coverage of the 2.4 & 5 GHz ISM/WiFi bands (outboard convertor?)

My sole complaint about the tinySA is it did not exist 20 years ago. It took many years for me to square buying my 8560A with my sense of thrift.

Thank you *very* much!

Have Fun!

Hi Reg, all the features will be implemented except for the tracking generator which will not be added. If you wish to use it for filtering adjustments, NanoVNA is a better choice.
Please bear with us as we have had to devote more development time to so many features.

I've got 2 nanoVNAs, a black clone and a nanoVNA H4 from R&L. And seriously considering getting a 2.8" nanoVNA H from them as well to keep with my FT-818ND for antenna testing.

The TG is pretty much a "would be nice". More memory for code and data is the most important.

Thanks for your contributions to both the nanoVNA and tinySA.

Have Fun!

I have a 8594E and 3585B as well as a TinySA. I wouldn't give up any of them. Each are proper tools that fill a niche.

Reg, I HAVE THREE 8560As crying in the garage, that I don't love them any
more!................. and they are right! LOL

New item for wish list:

The ability to control multiple tinySA devices via USB. With 3-5 tinySAs connected with two serving as signal generators driving a mixer and the rest examining directional coupler outputs, insertion loss, feed through and leakage would be easy to measure.

Reg,
? You can already connect as many tinySA's to your PC as you have available USB ports.? My main problem when doing so was identifying in code which of my tinySA's was connected to which USB virtual serial port.? Erik solved that problem by adding the deviceid console command.? See the Wiki for deviceid usage.

? I assign each of my tinySA's a unique device id based on their serial number (i.e. deviceid 2002001). I then place a label on the front of the tinySA with their device id and the name that I assign to it in code (i.e. specan1, specan2, sigen1, sigen2, etc.)?

? The only way I could see that it would have been easier is if Erik had allowed the deviceid to be alphanumerical.?Then I could have assigned my deviceid's with the same aliases that I use in my code (i.e. sigen1 or specan1).

? I have found the tinySa to be reliable, with repeatable results within its specifications, when used for test automation.? In its price range it stands alone for the breadth and range of console commands available to the user.? What's really great for the user on a budget is that no special drivers (i.e. VISA) or costly interfaces (i.e. GPIB) are required.? Once you learn to talk to the tinySA using the serial port in your chosen programming? language you are ready to go.

An example of creating to multiple serial port objects in C# is:

public static SerialPort sigen = new SerialPort();? //example of creating a 2nd serial port object?

I was thinking in terms of synchronizing a 2nd tinySA as an external sweeper for mixer testing from the SA side. However, likely better to do it from a PC.

Have Fun!

A preselector with low noise preamp would be handy.
Ability? to select EMC bandwidths like 9khz and 120khz with Quasi peak detector would be nice.

Quasi peak detector is available and I hope someone will test it in zero span mode
And 10kHz seems close enough to 9kHz (given the more rectangular shape) and 100kHz RBW is actually 112kHz.

You can use a second tinySA as a generator for the first.

Wish List #1 for Next Version of the TinySA? :
~~ Replaceable battery
~~ Optional Accessories such as:?
? ? ? ? ? Metal Case for one TinySA;? and larger case for two TinySA units.
? ? ? ? ? SMA Adaptors of various types
? ? ? ? ? A Small yet Sturdy Support Stand;
? ? ? ? ? Carrying Case
? ? ? ? ? A Longer USB Cable
? ? ? ? ? Two or Three Types of Attenuators

RBW -key.
