Not sure if it is available in low end scopes. It was a particular feature of their custom made MegaZoom FPGA and they had patented it I guess... yes it is. Read the Agilent manual for some of their s

generally, no, they still work with the same sequence. Agilent started (invented?) the idea of double buffering (I think it was introduced in MegaZoom FPGA) so that they already capture the next wavef

no, not really unless we are talking about late 80s and early 90s scopes like 2440... Update rate as important as it is, it is not really a "critical" spec. it is important in catching glitches and ra

I second Raymond's recommendation more specifically I recommend a Siglent. My SDS1202X-E served me extremely well as my very first digital scope and it came with tons of features and options as standa

yes and their close siblings TDS7000

prices of used scopes never go up because of "paying attention" to them or praising them on this forum or other forums. the only things that raises their prices are publishing repair or upgrading info

tds5054 for $1000!!!?? who in the world would buy that? That would be a rip off. Even TDS5104 doesn't sell for that kind of cash. This is not TDS7000 series, although even TDS7054 is not worth $1000 t

two things that you'll lose over the chinese scopes that you mentioned are size/weight and record length. These TDS5000 series are pretty bulky and "loud" (like TDS7000 I assume) and the record length

I second that but did he post a link? i dont think so. He has a good and valid question

please research the author first before debating the article !

some of the chinese fakes do actually work and identical to the original but since their date code is also old they ma not last that long I also got several fakes that didnt work until I got this one

you can just throw in a completely blank chip in there, no problem reading the old chip and writing in the new one doesn't do much and doesn't do any harm either as I have learned...specially now that

classic symptoms of NVRAM battery on the way out. cannot run the RTC but still has juice to keep some values. it is also possible that somebody replaced the chip or hacked a battery on top of it and n

my firmware was 1.16

You're kinda harsh on her (him!?) all handhelds use keys and push buttons and menus to change settings in fact I like its interface better than my Fluke 199C. If you know your way around Tek digital s

Now, this very much looks like a power supply problem or (less likely for the time being) the CRT driver board. the PSU (and also acquisition board) on these units run very very hot generally and need

psu is a good starting point but it could be your NVRAM about to give up at what stage during boot does it freeze? I would suggest you build the debug port and see the debug console first. That will g

the OP has not even plugged it in yet so it is not clear if it will cycle on and off if you have a auto transformer or isolation transformer, just start the scope at something like 50-60Vac and increa

nanovna V2 (also called S-A-A-2) goes to 3Ghz and has a very different structure than the commonly known nanovna but still on 2.8" display.... still it's a VNA though ...not SA

that is not a spectrum analyzer
