⭐ 0005 Siglent SVA1015X VNA Option Firmware Update Review

This is a review of the new firmware (V2.2.1.2.1) for the network analyzer option of the SVA1015X. This firmware fixes flaws and adds excellent new capability to the SVA including port extensions, multiple simultaneous plot types, additional calibration types including user cals, on-screen annotations, and a read only FTP server.

Thanks for taking the time to present the strengths and weaknesses of our products. Your feedback and style are greatly appreciated, Chris. - Jason

Chris, Compliments! It would be great if you could make an explanation video on VNA calibration. Thanks Gab.

Nice job Chris. You have helped Siglent make this a very worthwhile instrument. Keep up the good work!

[@Chris_Grossman]

Thank you

Wow ! Chris Going to get one now that firmware was fixed for Reference Planes ! Mike Aust WB6DJI Have fun in D1

[@Chris_Grossman]

They reference planes can be moved after calibration. It is a feature I use. The latest versions of firmware also allow log frequency sweeps. The head of the Siglent development team says the 3Ghz version works better below 10MHz than the one I have.

Nice Job Chris!

How do you like the newest firmware V3.2.2.3.3R1? How does the VNA compare against the NanoVNA V2?

[@sebastianpartzsch9102]

Cheers Chris, I am interested in the unit and since this is going to be a massive investment for my budget range, I can not afford to make a bad decision. That is why your review is very valuable for me. I am very much looking forward to more videos of this unit. Also, I really like how you give all this detailed background info about what measurements of certain DUTs should look like as I am a complete noob to vector network analysis. But it seems this going to be a unit worthwhile getting. So again a big thank you! P.S. Could you please, maybe if you find the time, also fit in a video where you explain and teach good operational habits with respect to VNAs and units alike?

[@Chris_Grossman]

I am planing on doing some measurement examples including the reasons I do things certain ways using the new improved firmware

Dear Chris, I have a SVA1032X and when I'm measuring a coil at 200khz I get on SVA 11.3ohm + j199ohm 158µH, with my LCR45 meter I get 200mOhm + j198.1ohm 157.6µH When I check this with calculation then both values are possible but with SVA Q factor is 18 & with LCR45 Q=990 Do you know what could be the cause? I use 1m coax cable, I've set Length port 1 to 1000mm and I use averaging. I have a calibration set and calibrated before measuring. I have no experience in measuring with analyzer so I don't know what things are important for measuring. My measurments are only up to 1.5MHz. I made a picture on setup: photos.app.goo.gl/ske7LLaawB1q2SA57 When I use the coil in series resonance setup with 106pF capacitor I can get +-400V @ +-900Khz while Q factor on SVA is 2.12 and I only use 12V pulse, so Q should be much higher. The LCR45 meter is giving me to high value for Q I think, so I have some trouble in figuring things out. Kind regards

A 50 USD NanoVNA is not a precision instrument bat can do simple 1,6 Mhz antenna for amateurs!

[@antoniohenriques7156]

VNA analysis starting 10Mhz? Tracking generator starting 5 Mhz? Cant analise a 3.5 Mhz antenna? Can't analise a 455 Khz Collins mechanical filter? Forget! Amateur radio will not buy!

[@Chris_Grossman]

The latest firmware works down to 100 KHz and works great for S21. However limitations of the input directional coupler limit the low end useful range of S11 to about 2 MHz

@@Chris_Grossman Hi Chris! Is a good new, any way that still is a limitation for the amateurs. Keep up the work, and thank's. Was interesting to compare the results with a small device that is coming for the amateur radio, Nano VNA! Many "miths" about the radio will come down! Siglent will sell a lot if they look for that "low end" off the market!
