content: For sale - a Lecroy 9354T in good working order.4Ch 500MHz 500Ms/s 100kpts/2Ch 1Gs/s or 1Ch 2Gs/s (with PP092 adapter - not supplied).I have replaced the floppy drive, updated the firmware to 8.2.2, replaced the fan with amuchquieter one, installed a new RTC battery and the maximum supported 64M of RAM. The 'scope is in good condition with light wear and tear only and has been in semi-regular use on the bench in the last 5 years, as far as I know everything works - the only thing I can't check out is the GPIB interface.Has software options WP01 and WP02 but if you have a GAL programmer data files to enable all the options are in the "files" section of the LeCroy group on Yahoo.£395£380 + p&p (in the region of £20). Payment via PayPal.UK only as too heavy to ship internationally.User manualService manualon the K04BB website.Overview (click on pictures for larger version).Risetime (using Leo Bodnar's very natty picosecond pulse generator) measures at 610ps (Ch1 was a little faster than Ch2-4 which turned in around 640ps).One useful feature of the LeCroy 'scopes is that the cal output is, in fact, a < 1ns pulse (if driven into 50\$\small\Omega\$) and I have confirmed that the output on this 'scope has a rise-time a shade under 1ns.Basic operation, measurements and calibration are fine (the small inset shows the AWG settings).Tinkering with zoom and maths functions.Screen dump via RS232 using 'scope explorer.Installed software options and system information.Finally bandwidth and response check - within 2dB up to the rated bandwidth

content: I can chuck in 4 new 100MHz probes but I don't have any LeCroy probes to go with it (wish I had)

content: Let's not get overly obsessed with probes. IMHO it is much better to buy your own probes than using the ones someone else doesn't want anymore (there is usually a good reason for that).

content: Quote from: nctnico on September 13, 2017, 09:33:19 amAgree except I'm not offering cast-offs, the 100MHz probes are the ones that I sell on ebay (and occasionally the forum) - in fact they are quite nice probes with much better than 100MHz bandwidth - and the 250MHz ones are some I bought as spares and are new and unused and currently on sale at £49 and some change from Farnell or a bit over £60 on RS.

content: So - as one of those beginner types - a question.I've been working my way into electronics gradually, Arduino is where I started but I've got STM32 dev boards and such - mostly for controlling models, user interface and generating telemetry so a fair bit of radio (bluetooth / WiFi) and logic (communications - I2C / SPI / UART) mostly from a programming perspective but I'm crossing over into design territory - gyro's, position sense, GPS and I'm totally dependent on what others build or how it is 'supposed' to work.I find myself needing to know more - so I need a scope, I've managed to get by without one but don't think I can any more.So would this be a good scope for diagnosing communication issues and reading what sensors are seeing vs what they are reporting, to test who isn't communicating as expected ?I've watched a fair number of Daves videos, looked at hundreds of scopes, only conclusion I've come to is that although an analogue scope many deem necessary I don't think such a thing meets my needs presently, so I think that I'm into Rigol 1054Z territory - but I'd rather have a secondhand high quality than a shiny new mediocre - if that makes sense.

content: Nice tool, Really glad I'm NOT broke right nowSo, If BenKenobi decides this is NOT the scope for him then I will have it ( assuming that it has not already gone elsewhere)

content: Quote from: BenKenobi on September 18, 2017, 02:00:12 pmNo, because it doesn't have protocol decoding. The 9354T is an excellent scope to look at high speed digital signals and do signal analysis (FFT, math) etc so it doesn't hurt to have such a scope on your bench. But for looking at I2C, SPI, etc a scope with protocol decoding is more appriopriate.

content: @DLJ - PM me your PayPal details and I'll send you an invoice.As BenKenobi is interested in I2C and other serial protocols I think he will probably best be served by the DS1054Z which offers serial decode - he asked for some advice by email and I sent a detailed reply.Ah, I see that while typing this reply nctnico has offered the same advice.
