![]() ![]() LECROY WAVESURFER 424 MANUAL SOFTWAREIf you want to spend a lot of money look for new Agilent, Tektronix (they also sell refurbished units), LeCroy, or Yokogawa stuff.Īny PC software that comes with the cheap o'scopes and even with Rigols or Insteks is usually rubbish. If you want some affordable quality, look for Rigol, GW Instek (esp. If you look for cheap stuff, look for Owon, Tonghui, UNI-T, Gaotek, Hangzhou Jingce, Jiangsu Lvyang, Tekway, or Siglent / Atten stuff (companies mentioned in no particular order). This increased the price for Rigol o'scopes outside China, something the regular importers were probably asking Rigol for. They convinced eBay to pull almost all Rigol o'scope offerings for alleged price dumping. Rigol recently cut off the air supply of many gray market Rigol sellers, selling out of China to the rest of the world. Very good value for money, except that people say they are not that accurate and the software is a bit fiddly.Ĭan anyone offer any advice? I am only used to analogue scopes back from my college days, DSOs are somewhat new to me. PC only is okay I suppose, although I worry about isolation when dealing with PSUs and video. The other current contender is a Hantek USB scope. ![]() It is quite a bit cheaper than the Tek too. ![]() The 1 meg buffer is attractive though, and people generally seem to think that Rigol scopes are pretty good for the money. Then there is the Rigol DS1102E which is 100MHz/1Gs/1M but that drops to 500Ms over two channels. It's handy for before/after comparisons and planning/design on the PC.Īnother option is the Owon PDS7102 at 100MHz/500Ms/6K which seems to be inferior in every way except that it has a USB port and is a bit cheaper. Lack of USB is a bit unfortunate too because I find it is helpful to snapshot things for reference when using the LA. It is also helpful when looking for problems when you are not sure where they are occurring. I don't know how much of a problem the small buffer is really as I don't have much experience with DSOs (only analogue), but my usual trick with a logic analyser when looking at a non-repeating protocol is to capture big chunks of data and zoom in to the bit I want. It's a nice, easy to use 'scope but has two disadvantages: only a 2.5k buffer and no USB. I am moving into doing arcade game systems as well, so need to check video outputs for example. I am a mostly doing stuff like LED display control and power supplies, up to about 20MHz at the moment. I am looking to get a digital oscilloscope and am trying to decide between a used Tektronix and a new Chinese one. ![]()
