Hi guys, Ultimately we all want to buy professional tools that are used in industry/research right? Not cheap toys that crash/break after a couple of uses. |O Use of a specific piece of test equipment in an academic setting/research paper is definitely a positive sign I would argue. It usually suggests that the author had/has some form of confidence in the tool to acquire scientific data. So why not go through a list of common test equipment and see how many results we get for each brand/unit? I would like to firstly like to break various test equipment manufacturers into 'tiers' based on 3 general factors: company reputation, perception and build quality. High end: Tektronix Agilent R&S These are the brands that have been with us for a long time now. We know that these companies generally produce high end products with good build quality. Mid tier: Rigol Siglent These brands generally cater for the entry level market. Rigol and Siglent are the two most trusted chinese brands and both produce equipment with a high performance to price ratio and reasonable build quality. Low tier: Hantek Fnirsi Unit-T These are the relatively new kids on the block so to speak. Products from these brands are sometimes labeled as' junk' or 'toys' and quality control is not great. So with those few companies let's hop on google scholar! Let's start by just searching brand names + oscilloscope: High end: Tektronix - 193,000 hits ('tektronix oscilloscope') Agilent/Keysight - 90,000 hits 'agilent oscilloscope' R&S - 5 k hits for ('R&S oscilloscope') Mid tier: Rigol - 6k hits ('rigol oscilloscope') Siglent - 1k hits ('siglent oscilliocope') Low tier: Unit-T - 893 results ('uni-t oscilloscope') Hantek - 577 hits ('hantek oscilloscope') Fnirsi - 7 results ('fnirsi oscilloscope') As can be seen by the results Rigol has the same results as R&S. These are of course not precise results but I believe they have some level of meaning. And the results do made some sense. The big boys get much more hits than the smaller players. Let's try something a bit more advanced, a spectrum analyzer. Let's start by just searching brand names + 'spectrum analyzer': High end: Tektronix - 28,000 hits ('tektronix spectrum analyzer') Agilent/Keysight - 191,000 hits 'agilent spectrum analyzer' R&S - 17 k hits for ('R&S spectrum analyzer') Mid tier: Rigol - 2.4k hits ('rigol spectrum analyzer') Siglent - 350 hits ('siglent spectrum analyzer) Low tier: Unit-T - 784 results ('uni-t spectrum analyzer') Hantek - 107 hits ('hantek spectrum analyzer') Fnirsi - Does not produce spectrum analyzers Let's do some searching on some specific models to get a better picture: High end: Tektronix - 142 hits ('RSA306') Agilent/Keysight - 728 hits 'E4408B' R&S - 61 hits for ('FPC1500') Mid tier: Rigol - 247 hits ('DSA815') Siglent - 27 hits ('SSA3021X') Rigol does well here. :-+ Low tier: Unit-T - no results Hantek - 4 hits ('HSA2030') Fnirsi - Does not produce spectrum analyzers Not looking good. :-- Feel free to do your own experimentation, this is nothing scientific, just a quick investigation I did due to curiosity :box:. |

You are missing GW Instek and MicSig. As the latter is relatively new, you won't get that many hits. |

And Owon. Four tiers may be better: - low: owon, hantek, uni-t - bottom: fnirsi et al. |

But also high end brands like Yokogawa, Kikusui, Tonghui There are so many brands out there that offer nice equipment. Sometimes to serve a specific niche. First thing to do when looking for equipment is research which brands sell the kind of equipment you are looking for. Even that can produce quite a long list. |
