Therefore, I tried to recommend a few devices, maybe not perfect, but with a good price / quality ratio. Especially when someone does not have great expectations. Many hobbyists are often satisfied with nanoVNA (e.g. tuning antennas in HF bands). I have nanoVNA myself and its capabilities are sufficient for me to tune the antenna working at 7 or 14MHz in the field (it can even handle 144MHz quite well). I am also able to give up some functionalities, because most often I need a VNA for duplexer tuning - nowadays the corac would be more useful in the 5GHz band... For such applications, I can safely look for cheaper solutions (not laboratory equipment). For example, the SNA5000 looks interesting, because it has an attractive price in relation to used equipment (which is not known in what condition it will be possible to buy it). On the other hand, VNA cannot be thoroughly checked when purchasing and any damage or problems may only come out after a long time, so you will not benefit from the protection of auction sites or paypal. Apart from the fact that most of the prices on ebay are crazy and the equipment is not worth that much. Such an example of the HP8712 which costs in the range of $1500-2000 on ebay. However, in Poland, you can buy one on flea markets for $260. Recently I tried to sell a frequency meter up to 40GHz (Anritsu MF2414B option 03) for half the price from ebay and nobody wants to buy it for that much :-// |

Then you know exactly the difference if you don,t have the money for it then it stops and you can,t make demands either. Tautech, Please do an extensive test like he has tested the SVA1015 and would also like to see the speed at different bandwidths (full span) and trace noise. The sales story of Siglent on Youtube could not convince me enough to buy the device. I called the importer (Eleshop) here in the Netherlands for a test, but they don,t have one in stock. Regards, Marcel --- End quote --- As it happens Shahriar has just released Pt1 of his SNA5000A review where he pushes some features to their limits, explores other functionality, engage with Siglent for some improvements and does a teardown. |

Tautech, The first thing I noticed was the slow sweep speed hopefully Siglent improves on this. My 12 year old E5062A is a lot faster. |

E5062A - Measurement speed: 35 ms (2-port cal, 30 kHz BW, 1 sweep, 201 points, correction off) SNA5012A - Measurement speed (100 kHz - 8.5 GHz, 10 kHz BW, 201 points) Uncorrected 33 ms, 2-port cal 66 ms I don't know what Agilent means by "correction off", but looking at 10kHz BW at SNA and 30kHz at Agilent - SNA seems to be faster after all. |
