What can it do that a SA has the capabilities to do? Does it have a tracking generator? I heard the reviewer say it has a “signal generator”.. It looks to be larger than the nanoVNA units I purchased a few years ago.
@@PowderMill re: " What can it do that a SA has the capabilities to do?" A SA can measure notch depth to >100 dB or better on an RF radio system dupelxer ... a VNA gives one vector (angle) results (reactive circuit characterization), a SA is 'scalar' (or magnitude) signal strength only device ...
I have the black unit with N connectors shown at the start. Very happy with it and do not intend (or need) to upgrade it. Will keep an eye on the USB port!
Thanks for the review. It would have been helpful to check what differentiates a good from a bad VNA, which is its dynamic resolution. I would agree that for a lot of ham related stuff 50-60dB is often enough, but if you want to a do a little more a higher dynamic is a nice to have. This unit translates to more than 350€ while everything you just showed works just as good with a VNA for under 100 € that goes up to 3 GHz. It would have been interesting to see in which situations it is worth to pay around 4 times the price for this unit vs. a low cost but often sufficient VNA.
I watched this video hoping to see mention of the dynamic range for tuning rejects on a duplexer, I'd like 90 to 100 dB, some sellers are claiming 100 dB dynamic range but the actual specs don't show that, not even close. I am interested in this due to the large screen size too, but need to confirm the rejection before considering a purchase.
Bought one from Dx Engineering. Could not turn it on with out the power cube attached even though the batteries were fully charged. I now have read this has happened to a few people. If you buy one, make sure you have a good return policy.
See a few negative views on this VNA, Outstanding devices at the price & the Pro's far outweigh the Con's when you consider VNA's have ranged anywhere from $20,000 to $500,000 dollars. I treasure my H-4 when needed, it's a luxury to have reliable digital analysis device for amateur work. Every Amateur should learn the fundamentals of the Smith Chart combined in use with the measurements of a noise bridge. ( Vector Network Analysis Rocks ! ) These units are not about perfection, they're about being damn close.
Hi, my SV4401A USB C port fell off after about a year of use. The reason being the port on the PCB did not properly align with the opening in the case. I was able to replace my socket, others I know will not be able to. Keep an eye out for the port mis-alignment, hopefully yours is better. A great unit otherwise and works well.
All VNAs have the same issue. Small screen and barely readable in bright sunlight. I will stick with Rig Expert. Also, only one has Bluetooth. Unfortunately, the one with Bluetooth is also expensive. Your review is great Mat. Thanks
The screen on one of these is significantly bigger than a RigExpert but I agree. For antenna work I will stick with my purpose built RigExpert for use at the home station or when on commercial repeater sites I'll use my Keysight FieldFox RF analyzer.
@@ohaya1 And how are you going to power a benchtop instrument out in the field or when hanging off the side of a tower 180 Feet in the air? Two completely different categories of instrument. One portable and one tethered to a wall outlet. Not to mention the Siglent you mention is more than a order of magnitude more in cost.
@@ohaya1 It's more about the small font than the screen size. There is a VNA that comes with an Android app. A nice 10" tablet screen gets a NanoVNA to just about something that I can stand to read.
If not the LibreVNA works great under Linux (Haven't actually tried in on anything else). Doesn't have a display, but since I'm not measuring antennas in a garden its not an issue for me.
It showed up as $393 including shipping to my home. A bit pricey but still far less than my Agilent (HP) portable spectrum analyzer that I use for cavity and duplexer tuning for public safety radio systems installations. I had tried most of the nanoVNA models and the TinySA, cool and cheap toys, but nothing I’d take out in the field.
For most hams cheap NanoVNA would be sufficient, if you need higher frequencies LiteVNA 64 goes to 6GHz and is 1/2 price plus it has a vibrant firmware development.
Dirt cheap compared to my R&S VNA's. Those cost me $21,000 and $36,000. Granted we are talking orders of magnitude in performance and functionality but for the hobbyist these little VNA's are cheap, really really cheap. Almost 4 times cheaper than even my RigExpert antenna analyzer.
VSWR is the ratio of energy moving from transmitter to antenna and the amount of energy reflected back to the transmitter from the antenna. One measures the efficiency of the system "at" a frequency or a freq range, but the point is the energy transfer. Therefore, one can say "the SWR (VSWR) is 1.2:1 AT 14.15 MHz", but it is not correct to say the SWR is 14.15 MHz.
At about 6:47 you reported that the antenna had "a rather good SWR of around 2.4 GHz". A correct report would be either "...a rather good SWR of x.x:1 at 2.4..." or "...a rather good SWR AT 2.4..."
Thanks used your discount code and VNA arrived in only a few days. Unbelievable what it can do for this low price.
Its a great VNA and it can even measure many things a spectrum analyzer can. I can highly recommend it

Excellent video. It's a noticeable upgrade over the nanovna type devices. UI looks much improved

I would like to get a tinySA Ultra with a 7 inch screen.
Just a matter of time...
Think I will stick with my sub £50 vna 🙂.
What do you have, and how do you like it?
Very nice instrument, Gotta have one !!
Thanks for the video!!
Great review. Thanks for including the purchase details.

Sent mine back to the UK supplier to fix. Same issue ! No quibble fix.....
How does this compare to the Mini 1300. I’ve been toying with buying an antenna analyser
Great but the 6Ghz model is out!! [SV6301A]
That's a great piece of gear right there but out of my price range. Thank you for demoing this "dream gear" for me. 😔
Very nice sized VNA. What is the price for this? Thank Paul

Where to order?
Very nice bit of Kit Matt
I want one. What's the price?

Interesting I didn’t realize it had a built-in signal generator.
I guess I need to read the manual again go to manual isn’t really that great…
I want one but not at the price. Sure there are plenty of clones but hate taking the risk
Well there is like 8 times fold difference in price of supposedly the same item between Banggood and AliExpress. What's going on with that?
Check again, you have not selected the right device on AliExpress

Too much for me. I still can't figure out which one to get. I need one that will do 1 GHz.
Nano vna pro Plus4 have 90dB dynamic range and price is less.
HOW MUCH RADIO DEVICES YOU HAVE?
TECHMINDS - YES.
SEND ME SOME MY WAY PLEASE.
But does it run Doom?
This vector analyzer has lower performance than original Nano Vna pro. In particular the dynamic range
Too expensive.
What device listen to iphone n android phone calls?

It has a Signal Generator as well. 🥸
But lower dynamic range than nano vna pro
Too expensive?? Seriously? It’s actually quite reasonable
VSWR isn't a frequency, it's a ratio. Scattered other 'glitches' in the vid.

Dufuq?
VSWR is the ratio of energy moving from transmitter to antenna and the amount of energy reflected back to the transmitter from the antenna.

Therefore, one can say "the SWR (VSWR) is 1.2:1 AT 14.15 MHz", but it is not correct to say the SWR is 14.15 MHz.
And your point being? Maybe you misheard something I said, maybe English isn’t your first language. Or you’re just randomly stating a fact? Who knows
At about 6:47 you reported that the antenna had "a rather good SWR of around 2.4 GHz".
A correct report would be either "...a rather good SWR of x.x:1 at 2.4..." or "...a rather good SWR AT 2.4..."
@@RechargeableLithium Obviously I meant "AT" and not "OF".. Well spotted though.. I dont need a lesson on this topic.. thanks
High price and poor performance
