Basic Operation
Left/Right buttons are mainly used to navigate through menu items. The selected menu item will be highlighted; its corresponding screen element will blink. Press UP/Down buttons to adjust. The OK button controls display/hide markers or confirm operations.
Pressing A (Run/Stop) Button once will freeze the current display. Press 'A' again to resume. The B (Shift) Button is used for quick functions.
Throughout this text, adjustable items will be labeled in red.
Waveform Storage
Waveforms can be saved to an mirco SD card or loaded to the display. You need a micro SD card to do this (not included). Please note that SDHC cards (high-speed cards larger than 2 GB) are not supported for now. Follow the below steps to set up your microSD card:
- Make sure your SD card supports SPI mode. (Max.menory: 2G)
- Format your SD card with the FAT16 filesystem.
When the microSD card is prepared, the FS (file save), FL (file load) and SI(image save) icons are enabled. Press the OK button on FS to save a waveform, or on FL to load the waveform from the microSD card. Also you could select SI for saving oscillogram in PNG format.
Signal Generator
The 3.5mm audio jack under the mini USB port is used for the signal generator. It outputs a square wave from 10Hz to 1MHz. Frequency can be adjusted via Fo ("frequency out"). The peak voltage is the same as the supplied power, or approximately 3.7v if powered from battery, and 5v when powered by USB.
Power Supply
The DSO Nano can be powered by the internal 500mAh LiPo battery or by the external mini-USB port. Charging takes about 2 hours 20 minutes to reach 4.12V. A brand-new unit can only run about 1 hour by battery, but the battery life will be extended after the LiPo battery is fully charged.
