But it’s looking expensive, even from TEquipment, about AU$2000 landed. --- End quote --- A couple things to think about that might save you some money on the logic probe: - there are people selling a non-Rigol version of the logic probe (based on designs that were developed in discussion threads on EEVBlog). On US eBay they run about $80 USD shipped to the USA. I'm not sure how the quality compares or what feature differences there might be (like supported signal voltages) different from the Rigol logic probe. - unless you need to have your logic waveforms displayed with and synchronized with analog signals, one of the many inexpensive USB logic analyzers might save you a fair bit --- End quote --- IMHO that is looking at it the wrong way. The cheap logic analysers offer little in terms of triggering versatility so in the end digital channels on an oscilloscope work just as well. A big plus is that you can see the signals change in realtime. A logic analyser always works in a capture-analyse sequence (no realtime display) while an MSO can do both. It may make a lot of sense to look at a used logic analyser from Agilent or Tektronix as these sell for peanuts nowadays if you want to have a wealth of triggering possibilities. A real logic analyser has a trigger system that consists of a programmable state machine which is immensly powerful. Then again I have the idea that digital channels aren't well implemented on B-brand scopes which automatically gets you into Keysight & R&S territory if you want decent MSO functionality. Bottom line: if you are looking at an MSO from one of the B brands, make sure you can return the unit for a refund if the digital channels can't do what you require. |

The GDFS-1000B serial manual from GW-Instek's site: - https://www.gwinstek.com/en-US/products/downloadSeriesDownNew/1679/133 (annoyingly, you need to have a free registered account) |
