The FNIRSI DSO153 Mini-Oscilloscope & Signal Generator is an upgrade to the DSO152 Mini-Handheld Oscilloscope. It offers a larger 1MHz analogue bandwidth, a faster sampling speed at 5MS/s, and also includes a signal generator with 14 waveforms. The oscilloscope offers a standard square wave calibration with a frequency of 1kHz. It can measure a voltage range of up to 800Vpp with an X10 probe. Due to the one-key AUTO function, it can display the measured waveforms without complicated adjustments. The oscilloscope can be connected through MCX for signal input or via BNC using the included adapter. The 1000mAh lithium battery has a 4-hour battery life and an Auto shutdown when not in use. Ideal for learners and students just starting in Electronics and for schools to put an oscilloscope on each learner’s workstation. This is a low-cost mini oscilloscope and signal generator that offers portability at a low price.
