The data capturing capabilities of Moku instruments can be significantly strengthened by the utilization of deep memory mode. With an extended memory depth and high sampling rate, users can export high-resolution data effortlessly via the ‘Export Data’ menu.
The deep-memory acquisition is available in the Oscilloscope and all Moku instruments that have an embedded oscilloscope, including the Lock-in Amplifier, PID controller, Digital Filter Box, FIR Filter Builder, and Laser Lock Box. Table 1 provides a summary of the number of acquired data points at different sampling rates in deep memory mode.

Deep memory acquisition in Moku app
Deep memory mode can be activated under the tab ‘Timebase’, as shown in the screenshot below. To save data, simply click the cloud icon located at the top center of the window. Then toggle the ‘High-res data’ option, select a desired data format, and click ‘Export’.
Data acquisition using APIs
Examples of saving data in the Oscilloscope deep memory mode using MATLAB and Python APIs are available on GitHub. Users are welcome to use these as a starting point to create their own scripts:
