7/2/2023 0 Comments Gabotronics xscope![]() ![]() My question is : has anyone used one of these (there are two models) using the manual? Is there anyone interested in testing one (via going through the manual) if I buy them one and they furnish me with notes? I would like someone to go through the manual page by page and go through the lessons and make notes on the manual. This is critical, I do not have the ability to write training manuals. So if I use this scope I do not have to write a manual. It has been on the market for many years since the KS. Remember the Rigol does not meet my spec of <100 so I still have to get the Xminilab. I ordered a Rigol DS1054Z today for 375.06 from Tequipment (with eevblog discount - thanks) to test the Xminilab. Interestingly this started as a Kickstarter project. Re: XSCOPExmega-xminilab oscilloscope cheap small not as good as Rigol. This is 44 pages and reads like a text book, ie a training guide. I have looked at many many scopes and maybe there is something better but so far I have not found any with something that is VERY important: A good manual. You can go back to the ‘Oscilloscope’ page tab and change the ‘Type’ (for trigger type) to ‘Free’ and to open channel 2 and check ‘Trace’ to see the horizontal line move relative to channel one’s trace.Hi I am looking for a scope and here are my specs (lets stay within them): - Under $100 - Good documentation - No batteries and no AC (to be powered by a laptop ps) - No used equipment I am looking for a scope that meets the above specs that can be used as a training tool at the high school level in a poor school system (ie one that cannot afford Rigol scopes). Also note that the voltage is to 3 decimal places while the Panel Meter is only to one (showing the Xprotolab has much better resolution). Rotate the potentiometer and note the voltage on channel 2 changing. Obtain 5V and Ground from any Arduino Digital port on the Grove shield using the Grove to pin cable. Connect this to CH2 input and CH1 to the +5V rail. The outside legs of the potentiometer connect to 5V and ground with the center lead serving as a voltage divider. Open the Xscope application on the Pis desktop. The ‘Meter’ tab allows 2 voltages to be monitors which is useful for checking out voltage regulators and circuit input versus outputs.īuild the circuit using wire jumpers and the potentiometer. Gabotronics Xprotolab Oscilloscope This kit contains a truly remarkable instrument that this author has. Displayed are triangle, square and a custom waveform. Go back to the ‘Waveform Generator’ tab and try different waveforms. Adjust the position to center the waveform in your graticule and the Gain to suit your taste. XScope: Xprotolab or Xminilab CH1: Analog Channel 1 CH2: Analog Channel 2 CHD: Logic Inputs Fast Sampling: 10ms/div or faster Slow Sampling: 20ms/div or slower Helpful tip Technical Detail Revision History Version Date Notes 1.0 September 2011 First revision 1.1 December 2011 Firmware upgrade for HW 1. Make sure XY is not checked and CH1 ‘Trace’ is checked. The ‘Waveform Generator’ should be set to sine, about 500Hz. The user interface is 4 buttons, and a real pain to use. Ive got one permanently fixed on my breadboard, but I wouldnt reccomend it. If no USB ports show up reboot the Raspberry Pi and start over. The only low-cost dual trace with onboard display I know of is the Gabotronics Xscope. If you do not see a sine wave click on the ‘Options’ tab and make sure you are connected. Using a jumper wire connect the AWG to CH1. First we will need a signal to display.Ĭonnect Arbitrary Wave Generator to Chanel 1 Input We will go step-by step to make sure they are correct. When you open the oscilloscope interface it will likely have the last user’s settings. Open the Xscope application on the Pi’s desktop. Make sure the USB on the Xprotolab is plugged into the Raspberry Pi. The verticle amplifier is calibrated in volts per division and the horizontal amplifier in time (seconds) per division. ![]() ganzziani/xscopes-qt cd xscopes-qt qmake make -j8. Oscilloscopes are used to troubleshoot a wide range of signals from audio (20 to 20000 Hz) to video (6MHz), digital (Hz to GHz) and radio frequency 10MHz to GHz).

However, you can still measure frequencies up to almost 1MHz. For digital signals, you can measure up to 16MHz.)Īn oscilloscope provides a graphical representation of a waveform over time.
