content: 40/20kpoints isn't much - doubt it's much different from the various other FPGA based analyzers out there.

content: Quote from: mikeselectricstuff on December 25, 2010, 11:17:02 pmThe Intronix LogicPort is 2k/34ch/500MS/s. The Open Logic sniffer is 6k/32ch/100MS/s, 12k/16ch/200MS/s or 24k/8ch/200MS/s. The Lecroy clearly has better specs (except number of channels), 20/40k is actually pretty good. It is also likely a much more professional tool, which means proper input circuit, signal integrity, triggering and well designed software. But I wouldn't be surprised if it was a lot more expensive than the competition.

content: the most important feature: it has the serial trigger featureno competitor has thatI have an MSO7034 with serial trigger, if you had it once yo will never go without.If I had not my MSO already, the lecroymwould be my choice.

content: Another interesting feature (for me at least) is that it integrates with number of scopes, including my Agilent 6000 series one. That can be used to time-correlate the analog signals to the digital ones.Regards,Janne

content: Quote from: jahonen on December 26, 2010, 10:32:46 amNeat idea but I'd be interested to see how well it works in practice - I suspect it would be slow, and it only apears to allow the logic analyser to trigger the scope, not vice-versa.QuoteThe ridiculous thing is the Lecroy box is cheaper than the Uart trigger/decode license for the Agilent (GBP1000) Fortunately the bus mode on the Agilent MSO means you can use an external MCU with a few lines of code as a UART to parallel converter to get useable serial decode for 1/100th the cost...!

content: I thought I'd resurrect this thread to ask if anyone has actually used the Lecroy Logicstudio.Lecroy seem to be still actively supporting it (the software has fairly recently been updated). The cost is £950 from Conrad including VAT and this compares with or is less than the option prices from Agilent, Rigol (on the 4000 series) and even Hameg if you count the cost of getting 16 digital channels.I'm looking for a new scope and the number of options rises if getting the Logicstudio is a useable alternative to having to get an MSO instead of a DSO.

content: The key line in all those is :Software options like CAN/LIN, I2C/SPI or RS232 can be installed at extra cost. Please ask us !each individual option is over £1000 plus VAT (on the standard Aligent web site) so unless they sell them at a discount you can't take full advantage of the MSO digital channels without spending a lot on top.
