32 digital channels on scope
32 digital channels on scope
(OP)
Hello,
We are expanding our engineering operations and need new kit.
We are currently using an Agilent MSO6034A scope which we need for the 16 digital channels.....
htt p://www.ho me.agilent .com/agile nt/product .jspx?cc=U S&lc=e ng&cke y=564674&a mp;nid=-35 165.536905 500.00& ;id=564674
However, we would prefer to have 32 digitall channels.
Does any reader know of such a scope with 32 digital channels? If it exists, it is hard to track down.
Also, i was going to re-order some more of our TDS range Tektronix scopes but was stunned to find that these have non-isolated channels.....it is the TPS range that have isolated channels. I thought all multi-channel scopes these days had isolated channels.

Yes, or they can, using the same master/slave setups as mac was talking about with scopes. National Instruments www.nationalinstruments.com, and Measurement Computing www.measurementcomputing.com, are just two that I know of that sell boards with this capability. As far as isolation, most boards and as the OP noted, a lot of newer scopes are wanting you to buy seperate isolation modules, typically sold on a channel-by-channel ba$i$.

Sorry about that, it's a long link. Search for ISO-5B modules on www.measurementcomputing.com if the above doesn't work, or follow the links for "external signal conditioning".
Short answer is $150-$200 per channel depending on how much amplification the module is doing. Note that these things typically only go to +/-40 vdc ratings (relative to the board ground), past that you need to look at other methods or suppliers. Be careful with these, I don't think they will behave with anywhere near the low capacitance of fancy scope probes, and also affect the frequency response of the signal (400 Hz is a rating on one of them...). Dunno how fast you need to go. National used to offer similar devices, with better ranges and faster response, for more money...but I can't find the isolation products on their site.

Agilent and Tektronics allow some of their scopes and logic analyzers to be connected together and function as one.
