Description: An oscilloscope can be a very handy instrument to keep on your workbench and this GA1102CAL digital storage oscilloscope will help you take your circuit analysis and troubleshooting to the next level. This 2-channel, 100MHz digital scope has a 1G Sa/s real-time sampling rate and comes with everything you need to get up and running. Each of the two included probes features an attenuation switch which will limit the bandwidth to 10MHz. USB-host functionality allows the scope to save waveforms to any USB flashdrive and USB-device functionality (accessible via the USB-A port on the back) allows the scope to communicate with the included software so you can import waveforms and data to the computer as well as software-control the scope. The scope also supports PictBridge compatible printers. The 7" color TFT display and on-screen menu system make it easy to access all of the features of the scope.

Note: The cover of the user manual below is incorrect, it should say "GA1000 Series" instead of "ADS1000 Series." We assure you that the user manual listed is correct.

  • 2-Channel, 100MHz

  • I bought this scope and used it for 2 days, its a REALLY nice scope, screen is smaller than what im used to (an owon, known for there big screens) but it preforms exactly as specked

    one thing to keep an eye out for is its 1GS/s ADC is only one channeled meaning it drops to 500MS/s at 2 channel mode but with the 1mhz per 4 mss rule of thumb it still works wonders

    the lights on the keypad and the wide display helps allot and the internal fan is very quiet

    the probes it comes with are FINE but feel very plasticy and im questioning there performance

    one major complaint i have (that some would call a feature) is at high frequency it has a strange persistence that cannot be turned off, seeing its fairly slow (but still reasonable) display this is very useful for detecting bursts that only show up every x number of waves but i wish it could be turned off

    all the knobs are clickable and have a function, useful, BUT some are not as clear as i wish

    i will do a full tear down at some point and link it here, but if your looking to mod it for better performance i would say with 1GS/s and 100MHZ what you see is probably what you get there probably not limiting the hardware at all!

    sorry this is not a proper review its 3AM and this is all the time i have but i hope it helped guiding some of you

    EDIT: i did some accuracy tests, it has a built in hardware frequency counter so i put in a 10MHZ sine from an OCXO that was calibrated against a GPS tamed TCXO last month and it showed 10.0001MHZ … quite good i think but i would not be surprised if this drifted but im not sure the clock source its using i than tested voltage with a calibrated 5v +/- 2ppm reference calibrated 3 months ago and i got 5.00v on ch 1 and i got 5.04v on ch2 both on 10x and 1x modes with supplied probes i also encountered 2 software glitches, one it would not let me measure one value 2 times at once in the measurement system, and it once glitched when taking a screenshot to not stop taking screenshots, a reset fixed them both

  • A lot less expensive than a brand name DSO, but still a lot for many of us to risk buying one without knowing exactly how well it actually performs and it would sure be nice to find a totally impartial fairly in-depth review from someone that has bought one. I’m currently using a Tek dual trace 100MHz analog scope and one of the main features that interests me is viewing pre-trigger information in order to see and help track down the source, for example, of a very short random pulse that’s causing a problem.

  • There is something wrong with my scope. I think some part of the electronics on the inside have some sort of defect (like a relay or something). =/ All I’m trying to do is look at the PWM output of an arduino, and the screen keeps turning off. The scope beeps, turns on, shuts off, clicks & beeps again. Sometimes it will keep trying to turn on, I’ll see a quick flash, hear the startup beep and it’ll turn off again. Has anyone seen this problem before? =/

  • Is there a Linux version of the software? Without that, the scope wouldn’t be worth much to me.

    • No but you can use RS232 for the software and that means no clumsy drivers so running the main program in WINE more than likely wont cause any trouble or you can write a simple driver for an already established O-Scope linux toolset (or wait someone will do it, or try rigol because im 99% sure its just a re-branded rigol)

  • “40K/CH Memory Depth” Choke…Puke…

    • im sorry there $400 100mhz scope does not have deep enough memory for you.

      • Which “there” are you using in that sentence? “there”, “their”, or “they’re”? My reply depends on that answer…

    • Well you know you can go get a something like a Rigol DS1120E with one million point deep sample memory for about the same price (less if you don’t mind used). The only thing you’ll give up is the screen, 800x480 for the ATTEN vs. 320x240 for the Rigol.

  • I was pleased to note that the maximum input voltage (on the signals) is 400V. Unfortunately, the vertical section is listed as only going to 5V/div – I’d much rather see 20V/div, or even 50V/div. This is useful if you need to look at AC power lines (“mains” for our European friends) without worrying about “letting the smoke out” of the ‘scope. (BTW, doing this requires extreme care – those lines can be lethal.)

    • The 10:1 probes make it 50V/div. If it is like all the other digital scopes out there, you can select the probe attenuation in the setup and the voltage readings will be correct.

      • That’s great if you’re using a probe. Most of my fixtures are designed to NOT use the probes, but rather jumper cables or coax to the ‘scope. I’ve been interested in electronics since the mid 1960s, and have yet to encounter 10:1 jumpers, and the 10:1 coax attenuators are generally designed to work on RF, not power line frequencies.

        BTW, it’s much easier to “shield” the connectors that have power-line connections if you’re using jumpers than if you’re designing to connect ‘scope probes. This is very important to keep stray fingers away from 120V.

        • 10/1 attenuators that work from DC-1mhz (3db down) are fairly cheap they simply contain a 1% 9Meg resistor in series … you can make one yourself using $2 in parts

          but if you’re working on mains a 1gs scope might be a bit much

  • The “Replaces” link, https://www.sparkfun.com/products/10806, when clicked brings you back to this page but in another window. It should point to https://www.sparkfun.com/products/retired/10806

    • Hopefully this shouldn’t be an issue again. We are not adding the “Replaces” section anymore now that we have the “Previous Versions” box on the right hand side of the page above the Skills.
