User Manual ADDR: In the address bar, "R" represents the read operation, and "W" represents the write operation; DATA: It is the data sent by a read or write operation; ADDR ACK: "Y" means response, and "N" means no response. 2.9. Save/Recall Oscilloscope setups, waveform, and reference waveform files can be saved to internal oscilloscope memory or to a USB storage device, the CSV and picture can be saved to USB storage device, the default save type is setups. The saved setups, waveform and Ref can be recalled from an USB Host interface on the front panel to connect an USB device for external storage. 1. Setup It’s the default storage type of the scope.
It saves the settings of the oscilloscope in internal or external memory in “.set” format. Up to 9 setting files (No.1 ～ No.9) can be stored in the internal memory. The stored settings can be recalled. 2. Wave (Binary) The scope saves the waveform data in memory in “.lwf” format. Up to 9 wave files (No.1 ～ No.9) can be stored in the internal memory. The stored wave can be recalled. 3. Reference The scope saves the waveform data in memory in “.ref” format. Up to 9 Ref files (No.1 ～ No.9) can be stored in the internal memory. The stored Ref can be recalled, a total of 2 Refs can be recalled.
At recall, the Refs will be displayed on the screen directly, at the same time, the time base, volt/div and level position when saving the Refs file are displayed. When the Refs is not needed, you can select “Close”. 4. CSV It saves the waveform data in external memory in “.csv” format. The stored files contain the waveform data of the displayed channels and the main setting information of the oscilloscope. The recall of CSV file is not supported. 5. Picture Save the oscilloscope display interface to external storage in “.bmp” format. The recall of picture file is not supported. 39 / 67
