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. XScopes User’s Manual Page DS-XScopes-2.2 September, 2012 2. ![]() 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). Figure 1: Xprotolab and Xminilab, Top View Figure 2: XScopes Block Diagram. 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. 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. ![]() 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. Make sure XY is not checked and CH1 ‘Trace’ is checked. The ‘Waveform Generator’ should be set to sine, about 500Hz. If no USB ports show up reboot the Raspberry Pi and start over. View datasheets for Xscopes Manual by SparkFun Electronics and other related components here. 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. 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). Can you find 'ID 16d0:06f9 MCS Gabotronics Xminilab' in lsusb output Is the green LED on the Xprotolab board blinking Top. Voltage is displayed vertically while frequency (or period) is displayed horizontally. The time might be very brief (on the order of nanoseconds) up to a second. 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. Its features:ĭual channel Oscilloscope (The analog bandwidth is set at 200kHz. ![]() ![]() * Original SparkFun product description and images used with Sparkfun permission.This kit contains a truly remarkable instrument that this author has seen in no other Arduino/Raspberry Pi/Breadboard kit: A fully functional oscilloscope! Gabotronics makes a range of low-cost scopes the one we are using is under $20 USD. Graphic OLED display 0.96", 128圆4 pixels.ATXMEGA32A4U 36KB Flash, 4KB SRAM, 1KB EEPROM.We can hear you thinking, “This board has an ATXMEGA32A4U, an OLED display and USB interface? Scope or no scope, this would be a great development board!” Well Gabotronics had the same thought and installed a USB bootloader so there’s no need for specialized programming tools! The awesome functionality-to-size ratio is due, in part, to the ATXMEGA32A4U microcontroller on board. The scope itself obviously allows simultaneous sampling of analog and digital signals but also has several advanced trigger modes, XY mode for plotting Lissajous patterns, phase differences or V/I curves, Spectrum Analyzer with different windowing options and even an arbitrary waveform generator with sweep on all parameters. You can also connect it to your PC and use Gabotronics' XScopes software to control the device and view waveforms. The on-board graphic OLED matrix can display waveforms, measurements and menu systems. At only 1 x 1.6 inches, this oscilloscope can be plugged directly into a breadboard. The XMEGA Xprotolab is exactly that: The first ever mixed signal oscilloscope, logic analyzer and arbitrary waveform generator in a DIP module. What you probably don’t imagine is a DIP package. THIS PRODUCT HAS BEEN RETIRED FROM CATALOG AND IS NO LONGER FOR SALE. THIS PAGE IS MADE AVAILABLE FOR THOSE LOOKING FOR DATASHEETS AND THE SIMPLY CURIOUS.ĭescription: When you think about a piece of equipment like a mixed signal oscilloscope you usually think of, well, a piece of equipment.
