Moku:Oscilloscope


Features

Moku:Oscilloscope features 2 analog input channels with 200 MHz bandwidth, and independent control of AC / DC coupling and 50 Ω / 1 MΩ input impedance. 

The new multitouch interface allows you to intuitively adjust time and voltage levels. Warning: after 10 minutes with Moku:Oscilloscope, using a conventional oscilloscope may annoy you.

Intuitive Shortcuts

  • Double tapping on a waveform intelligently autoscales that channel.
  • Double tapping on a blank space autoscales and distributes all channels.
  • Double tapping the channel trigger point marker sets the voltage or trigger offsets to zero.
  • Create new voltage or time cursors with a dedicated button. Hint: Swipe the button up or to the right to spawn and place voltage or time cursors in one motion.
  • Touch a cursor's label for tracking options, like track maximum/minimum/mean as well as maximum/minimum hold.
  • A long press (touching and holding) directly on a channel's waveform brings up a pop-up menu for more options.

Histograms: Live, full frame rate histograms can be shown, which can be useful to diagnose sources of error such as electronic crosstalk.

Reference Trace: Keep a ghost image of your data on the screen to compare with live data. If you rescale your live channel, you can also easily rescale this reference trace to the current scale settings by double tapping.

Interpolation: Switch between sin(x)/x interpolation for observing smooth, high frequency signals or linear interpolation to preserve sharp features. 

The Settings side drawer gives you an old school way to configure your data acquisition. Adjust channel settings (scale, impedance, AC/DC coupling) in the Channel tab, including both input channels and math mode. When the waveform generator is enabled you can also switch to observe the output via an internal digital loop-back.

Use the Time tab to access time base, triggering, averaging and persistence settings.   Moku:Oscilloscope supports normal and precision acquisition modes.

FAQ

+ Can I set the channel offset in screen divisions while zooming?

To zoom in and out while keeping the channel offset fixed on the screen, simply pan up or down with two fingers held together. This 'rapid zooming' technique works horizontally and on other instruments as well!

+ What is the difference between "Normal" and "Precision" acquisition modes?

Moku:Lab records samples from the analog inputs at a rate of 500 MS/s. When looking at long time spans, the data's sample rate is reduced to display the trace on the screen. In "Normal" acquisition mode, the input is simply downsampled; that is, only every Mth sample is taken. This can cause aliasing of high frequency signals: for example, a high frequency sine wave may appear as a lower frequency sine wave when the oscilloscope timebase is zoomed out. In "Precision" mode, the input is lowpass filtered (averaged) before downsampling. This reduces aliasing artifacts and increases the resolution of the trace. Note that in this mode, high frequency signals can be filtered out, so the oscilloscope trace may appear to be zero even if a high frequency signal is present at the input.
