    Anyone have a recommendation for an entry level oscillscope and waveform generator? I was looking at Saelig and they have a Rigol combo for ~$850 and also an Owon combo for ~$700. Both scopes are advertised as 100 MHz.

    Look at that, it's also a meter :)

    I never knew Rigol amd Ownen had combo's..

  3. I guess I'd go with the Rigol.
    I just got a DG1022 $379 (20MHz sine) today.
    The DG1022A $499 goes to 25MHz, but for $100+ more?
    (Isn't the 'scope ~$400??)
    I played with it a bit.. there were lots of built in arbs,
    none seemed that useful to me.
    Arb's I'd like to have... (kinda like EE apps?)
    Multiple pulse sequences,
    Noise source with LF and HF adjustable limits,
    I could try programming..???

    It does have trig/burst and modulation bnc inputs on the back. (I
    haven't tried either.)

    I have a Rigol scope and like it. I suspect the Owon may have a larger
    display. there are some reports that the Rigols are easier to use but that
    may be a familiarity issue. Similar to the differences between Tek and
    LeCroy instruments.

    At a previous job, I used a Saleae Logic
    (24 megasamples per sec, 8 channels) and it worked well. It is not
    what you would use to (say) design a motherboard for a 2 GHz CPU, but
    it was good for what I wanted. I was using it to monitor a TTL-level
    serial bus. I recorded the data on one PC, then loaded it into another,
    told the Logic software "this is 8N1 serial", and it decoded the bits
    into bytes. It also knows I2C, SPI, and similar formats.

    It needs a host computer to run; if it can't dump data into the PC fast
    enough, the software will tell you, and offer to back off the sampling
    rate. The software is in Java and it will work on both Linux and legacy
    systems. You can use a low-spec/old PC to capture with, but for
    analyzing long capture files, it helps to use the biggest PC you can get
    your hands on.

    Standard disclaimers apply; I don't get money or other consideration
    from any companies mentioned.

    You could have a look at TiePie engineering USB oscilloscopes, such as the Handyscope HS5 oscilloscope with arbitrary waveform generator.

    Key specifications of the oscilloscope:
    2 channels, 14 bit, 500 MS/s, 250 MHz bandwidth, 20 MS/s 14 bit continuous gap free streaming, 32 MS memory per channel, 1 ppm time base accuracy.

    Key specifications of the Arbitrary Waveform Generator:
    1 µHz to 30 MHz waveforms, 240 MS/s, 14 bit, 64 MS memory, -12 to 12 V output (24 Vpp), 1 ppm time base accuracy.

    A bit pricy for the number of channels. The Intronix LogicPort is a
    better buy in terms of cost per channels. I suppose 8 channels is
    enough for some apps. I would want at least 9 channels so I could
    monitor an 8 bit bus and a strobe or clock.

    34 channels for <$400. I've used this device and it works well.
    Although I haven't used it enough to uncover any flaws. All devices
    have flaws, right? Oh, one is that they don't support Linux. I've
    asked. This is one reason I haven't bought one yet. I want to be able
    to use all my tools if I make the switch.
