Very cool @PhilC . When you get a analyzer with lots of capability its not as simple as the little Chinese hardware thingies. On that note I just ordered another HP digital analyzer, my third. The plugins from the first two will work in this one a HP 16700B which is the fastest of the series without a display. Its meantto work with a monitor or remotely with vnc. It will give me a 4 channel scope and 200+ digital channels. I'm still looking for a part number on the board mass lead connection to make daughter cards so I can lift a 68k or 40 pin chip and plug in one analyzer cable to access all the signals just plugging in on cable. Let me know how you make out with your Tek analyzer.

Yeah you've got that right @PaulJ with not being simple. I'm willing to bet it'll take a while just to get it set up how I want it first.

Spent an hour tonight trying to work out this new LA. Good job it's got a manual with it as I'd be struggling otherwise. I guess it's called being spoilt with modern computer technology. I'm sure a new LA like this is all singing and dancing and easy to use BUT also probably £10k to boot.

Must go read the manual.

@PhilC , its not that the analyzer is overly complex, its that it can do a millions different things and ways to trigger. The HP has like a selection of 20 capture cards including a very nice dual channel scope card which is much better than my 200 mhm scope. If you want you can put in 5 dual channel scope cards and trigger them from conditions programmed conditions in the digital analyzer cards. Each card variety has a 300 page manual. Very capable but hard to use which is frustrating.

When I was at Motorola the hardware guys used them with the header plugs so you could easily connect up to all processor lines. When we had a issue it didn't take long before the setup got beyond my abilities so I'd tell a hardware designer what I needed and what condition to trigger on and two minutes later I'd be up and running. Unfortunately when I purchased the analyzer it doesn't have a hardware engineer taped to the side. Back in the day hardware engineers had priority and they were always in use unless they had a firmware issue they needed fixed. Now I can play and learn to my hearts content. Its hard to believe how cheap they are.

When you get your analyzer up and running post sample captures, maybe something @rubber_jonnie can use trouble shooting his mega.

Here's some basic stuff I posted re my Mega that's not working. Using the LA was a lot easier than I expected TBH, all I did was connect to GND on the CPU, then connected the LA channels to the pins I wanted to look at. It's much more granular than the scope TBH.

Thanks @rubber_jonnie that's what I've done with the usb one Icky gave me but it's more of a case of learning this new LA.

Hoping there's not going to be an earthquake this side of Christmas.

Looks like there maybe already was one!

@PhilC Ahh I see, nice looking unit, looks bomb proof!

I expect the manual is not thin...

[PhilC]

Yeah, thin is not a word to describe this manual

[Icky]

In other news, I got sent a logic analyser by @Icky which I found incredibly useful but a bit limiting with only 8 channels *not being ungrateful at all thanks Icky ). So this turned up today.

No ungratefulness taken - Its what started you on this LA journey , my job is done.
