entry level logic analyzer

[jabramo]

I think that Open Logic sniffer is worth adding to the mix. It's only 50 bucks and the specs at the price point aren't to shabby.

Capture 50MHz+ waveforms on 32 channels

    200Msps captures up to 100MHz waveforms on 16 channels
    100Msps captures up to 50MHz waveforms on 32 channels

16 buffered channels, 5volt tolerant

    M74LCX16245DTR2G transceiver tolerates voltages from -0.5V to +7V.

216K Block RAM supports following memory configurations*

    8 channels with 24K sample depth
    16 channels with 12K sample depth
    32 channels with 6K sample depth

What about the scanalogic?  4 port 20mhy logic analizer.I am very happy with it, I'm still at the begining.

I recommend the Intronix LogicPort:  http://www.pctestinstruments.com/  $389 plus postage.  It has 34 channels @500MHz sample rate, can handle +/-40V DC and 15V pk-pk pulses on inputs and lots of other good features.  I have owned and used one for a couple of years with no problems.

My experience with the Logicport is not so good. I have issues where the USB connection got lost which results in the program stopping without saving the setup. The 2kbit memory is also way too short and don't expect to do anything usefull with the 500MHz samplerate. You need real probes and a real logic analyser. Better go for the cheap Chinese logic analysers if you want good value for money.

Do you mean a clone? Because there's a Chinese clone of the Logicport available for $80.

And then tere is the ZeroPlus.

Well, considering that the OP is new to electronics - and looking for an entry level LA with, I would assume, entry-level prices - then I'd think the Zeroplus isn't really an option.

LAP-C16032 is about 100€.

If  by "about" you mean ~€140 with shipping (UK) - yes, I suppose that could be construed as "about" €100 (although not by me).  It's also "about" 80% more money than what the OP was asking about in the initial post.

No, the other Chinese logic analysers mentioned in this thread. IMHO they offer better value for money than the logicport.

Ok, understood. But you seem to be in the minority in this thread in terms of your feelings about the Logicport. I have a ~$20 clone of the Salae/USBee and an ~$80 clone of the Logicport - I use the Logicport clone much more often.

A couple other options for LA, some also have scope functions  too. The mso19 has a pattern generator for sending data as well as recording data. The QA100 has a function generator . These are not based on the CY series of chips and do all the work in the hardware.

The scope functionality is usually pretty pathetic, however. For the MSO-19, 200 MS/s, 50 mV/div to 500 mV/div (good luck with low level signals or high voltages), and only 1000 points memory. The QA100 is only 100 MS/s. This is decent for a logic analyzer, but a scope needs a much faster sampling rate since it's trying to reconstruct an analog signal, one with pretty fast edge rates in the case of most digital signals.

Just an FYI, I found a used Zeroplus LAP-C 16032 on eBay for $60

Looks to be complete and the price is great ($140 plus new).

Marmad,

What is the name of the clone you are using?  Does it work with Intronix software or some other software?

Thanks
