The Device layout lets you place Device displays also outside the main application, therefore it might come handy when multiple monitors are connected to the computer. Device displays outside the main application in Dynamic mode 26 www.poscope.
POSCOPE4 AND MEGA1+ MANUAL Device controls GUI All supported real devices has their graphic representation in PoScope4. We call then Device control GUI and as name suggest we use them to setup and control connected devices. Buttons to toggle their visibility are located at the bottom of the main PoScope4 window.
POSCOPE4 AND MEGA1+ MANUAL The color of graphic signal representation of each channel is also customizable by clicking the color panel below the channel name.
POSCOPE4 AND MEGA1+ MANUAL Poscope Mega50 control gui (analog mode) PoScope Mega50 control gui (digital mode) The color of graphic signal representation of each channel is also customizable by clicking the color panel below the channel name. Signal color settings 29 www.poscope.
POSCOPE4 AND MEGA1+ MANUAL OSCILLOSCOPE Oscilloscope is an electronics measurement device that visually represents an electric signal, either alternating or direct current (AC or DC). An oscilloscope graphically shows variations of voltage. As such it is appropriate for measuring and analyzing fast changing electric signals. For this example we connected the analog generator output to oscilloscope channel A of the same PoScopeMega1 device. You can do that by using 2 probes. Plug them to CH.
POSCOPE4 AND MEGA1+ MANUAL You might come across the message: Device not in analog mode. In that case you will have to open the PoScopeMega1 controls and switch the device back to analog mode in the DAQ section. ‘’Device not in analog mode!’’ Error message Device controls – digital mode 31 www.poscope.
POSCOPE4 AND MEGA1+ MANUAL Capture mode A window will open, showing graphical representation of a measured signal. To expand the timebase, find the magnifying glass icons in the bottom left corner of the oscilloscope display. Magnifying glass icons for timebase setting 32 www.poscope.
POSCOPE4 AND MEGA1+ MANUAL After expanding the timebase you will get far better graphical presentation of the observed signal. To view the controls of the device, you have to click the device buttons area of the GUI. To view the device controls of oscilloscope PoScope Mega1+, left-click the PoScopeMega1 button. If you have multiple devices connected, they will be listed here. Previously you have to set higher number of device instances in the settings menu.
POSCOPE4 AND MEGA1+ MANUAL Since the analog generator outputs a voltage amplitude of no more than 2V, you can set the channel A knob to 2V. You will get graphical representation shown below. Some signals change very fast. To catch the desired event, you can use triggering. Trigger is a standard oscilloscope function that allows you to catch the live signal at some particular point so you can closely analyze it.
POSCOPE4 AND MEGA1+ MANUAL Analyze mode When pressing analyze additional control with yellow colored selector appears on the top of the waveform. This control is called analyze overview and its purpose is to give users the idea of overall content of data in buffers for further analysis. Data displayed on overview control is ordered by time so the oldest data is left-most and most recent data is right most.
POSCOPE4 AND MEGA1+ MANUAL The oldest data The most recent data Oscilloscope display in analyze mode with Overview window To read the amplitude of the signal, you don’t have to constantly calculate the Volts/div X number of divisions. Just use the 2 vertical cursors available, C1 and C2. Find them in your oscilloscope window, click & drag to desired position. Below you will find Data table command. It opens small table with current values of voltage amplitude and time difference between C1 and C2.
POSCOPE4 AND MEGA1+ MANUAL Additionaly you can just hover mouse over the signal and cross cursor will show you the value under the mouse cursor. 37 www.poscope.
POSCOPE4 AND MEGA1+ MANUAL Hint: If you click with left mouse button in the data table you can toggle between time calculation between two cursors and frequency calculation. In the right-bottom corner you can see estimated frequency calculation. It's an estimation and its accuracy depends on your sampling frequency setting and your signals applied at the inputs. If your sampling frequency is too high and signal frequency is too low the estimated calculation might be wrong.
POSCOPE4 AND MEGA1+ MANUAL 39 www.poscope.
POSCOPE4 AND MEGA1+ MANUAL Exporting data When needed, you can export the measured data to external file. Filter out data of interest (channel A, B) and current chart / selected buffer range, and then click Export. Supported file types are: .csv, .xls, .html, .pcm - exporting to PCM will create additional txt header file with info (available only for oscilloscope and recorder) Oscilloscope display in Analyze mode with export settings 40 www.poscope.
POSCOPE4 AND MEGA1+ MANUAL PoScopeMega1+ sampling frequency (analog and digital DAQ mode) If you change sampling frequency knob you will note that label under the knob is changing from Pipe to Buffer. Pipe and Buffer are names for two different data transfer modes. Data is transferred over full speed USB 2.0 which has speed limitations (1,5Mb/s theoretical). Mega1 can sample faster than we can transfer data over USB thus we introduced these two modes. Pipe mode: sampling is slower than USB 2.
POSCOPE4 AND MEGA1+ MANUAL Using multiple devices in PoScope4 Sometimes there is a need to measure more than 2 analog signals. PoScope4 supports multiple devices and multiple instances of same type of device. Each device gets its own control GUI. When you have more than one Mega1+ (or any other supported devices) you can set up PoScope4 to load multiple instances of Mega1+ by clicking Settings button in main menu.
POSCOPE4 AND MEGA1+ MANUAL X/Y SCOPE There are applications where we need to know phase differences between two or more varying voltages. Oscilloscope can be used to track phase differences between multiple input signals. X/Y scope plots them out as one voltage versus another. If input signals are periodic resulting curves are called Lissajous figures.
POSCOPE4 AND MEGA1+ MANUAL You might come across this window. In order to track phase differences, both of the channels have to be active. You have to turn on the signal on channel B on the Mega1 device control GUI. ‘’One of the channels is not active’’ error message in XY mode Channel B on/off button on Mega1 device controls 44 www.poscope.
POSCOPE4 AND MEGA1+ MANUAL In order to see the phase differences, you can open oscilloscope display and enable the trigger function on one of the channels. One of the signals will freeze, the other will move across the display in relationship to the first one. Now let’s draw some basic Lissajous curves. If we set ratio of frequencies to 2:1, for instance 5kHz on channel A and 10kHz on channel B, we get following curve. 45 www.poscope.
POSCOPE4 AND MEGA1+ MANUAL Lissajous curves at frequency ratio 2:1 When we change the ratio to 1:2, for instance to 10kHz on channel A and 5kHz on channel B, the curve rotates by 90°. At greater ratios we just get more twists. Lissajous curves figure infinite at frequency ratio 1:2 46 www.poscope.
POSCOPE4 AND MEGA1+ MANUAL When there is 90° phase shift between the two signals the XY display draws a circle. There are many different examples of Lissajous curves. Let's switch shape of one signal to triangle. Channel A is triangle and Channel B is sine 47 www.poscope.
POSCOPE4 AND MEGA1+ MANUAL SPECTRUM ANALYZER Spectrum analyzer measures signal amplitude over wide range of frequencies. It plots a waveform of signal amplitude (Y axis) against frequency range (X axis). With spectral analyzer you can find out the dominant frequency of a known signal and the amplitude / frequency of the unknown or undesired signals, as well as signal’s other spectral components (power, distortion, harmonics, bandwidth, etc.
POSCOPE4 AND MEGA1+ MANUAL Waveform below shows frequency spectrum of periodic signal coming from analog generator. Frequency of the signal is set to approximately 10 kHz. Waveform is being plotted as signal amplitude (Y axis) vs. frequency (X axis). Clicking Axes gives you additional set of settings to examine frequencies of the input signal.
POSCOPE4 AND MEGA1+ MANUAL In the Frequency analyzer, cursors are also available. Drag and drop them with your mouse to find out which frequencies are most dominant. To view the relationships between C1 and C2, click on the data table. Frequency analyzer with data table open 50 www.poscope.
POSCOPE4 AND MEGA1+ MANUAL Click on Analyze button will take you to Analyze mode. In analyze mode the overview control will open. You can resize the yellow selector by hovering your mouse over it and use the scroll wheel to make the yellow square smaller. When done, you can pan the waveform left and right to make a FFT analysis over selected part of buffer. In Analyze mode, you can also export the data to various formats of an external file. To return to live signal, just click on Capture mode button.
POSCOPE4 AND MEGA1+ MANUAL RECORDER Analyze button is limited with the amount of RAM memory installed in a workstation where measurements are taken. To avoid the limits of RAM memory, you can save measurements to an external file on your disk. Therefore the total amount of measuring samples will be limited with the total capacity of your hard drive, SSD or USB drive. To run the recorder module of PoScope 4 software, click the REC icon in the device functions area of PoScope 4 software.
POSCOPE4 AND MEGA1+ MANUAL Acquired samples can be recorded to PoScope4 recorder file or PCM file (pulse-code modulated data). PCM is intended for use in 3rd party software, therefore it can’t be open in PoScope4 application. Recording to PCM will create additional txt header file with following info: number of channels, data size per channel, bit ordering, sampling frequency etc. Recorder settings Once recording, you can stop it by pressing recording button again.
POSCOPE4 AND MEGA1+ MANUAL Once open, you can switch pages and resize the overview selector. If you hover over the waveform you can change the timebase using mouse scoller and drag the waveform left and right using you left mouse button. Data table and export features are also available as in the oscilloscope display. 54 www.poscope.
POSCOPE4 AND MEGA1+ MANUAL LOGIC ANALYZER Logic analyzer is an electronic measurement instrument, capable of capturing and displaying multiple signals from a digital circuit. With this powerful tool you can observe many digital signals at the same time and perform exact time measurements.
POSCOPE4 AND MEGA1+ MANUAL Run the Logic Analyzer by clicking its icon in the Displays tab of PoScope4 software: Below you can see an example of displaying digital ports of a PoKeys input / output device. As in oscilloscope mode, you can click Analyze button to closely view the captured data. Logic analyzer waveforms 56 www.poscope.
POSCOPE4 AND MEGA1+ MANUAL When in Analyze mode, use the yellow selector above to select the part of captured data for even closer observation. Resize the yellow selector with scroll wheel and drag it to point of interest. Logic analyzer in Analyze mode with Overview window open On the right side of the Logic analyzer display you will find 2 tabs. Under measurements you will find width, frequency, period and duty cycle. Values will change as you hover over the diagram.
POSCOPE4 AND MEGA1+ MANUAL When done, you can hover over the part of the certain square waveform to see additional details. You can export the data selected in overview window to an external file in various formats. Logic analyzer export settings Every channel can be switched off/on simply by selecting it in a Windows manner. Click on Port A.6 and hold CTRL then click on Port A.7. Both channels are now selected. Now click on channel settings icon (any).
POSCOPE4 AND MEGA1+ MANUAL Now overview and main chart will be updated and only Port A.6 and Port A.7 channels will be visible. Hint: By double clicking on channel names one can rename channels. 59 www.poscope.
POSCOPE4 AND MEGA1+ MANUAL I2C DECODER Inter – integrated circuit simplifies the hardware part of electronic devices. It consists of only 2 wires. One is used for clock synchronization, the other one is for data transfer purposes. On each I2C bus you will find one master and multiple slaves. Most I2C busses work on frequencies up to 100 kHz, which can go higher if needed.
POSCOPE4 AND MEGA1+ MANUAL Use the overview yellow selector and mouse scroller to select part of data for analysis and decoding. Pin that has most dense pulses is usually the clock. You can also rename Pin by double-clicking its name. The second pin is data. I2C decoder clock (SCL) and data (SDA) lines 61 www.poscope.
