Description
Overview
GAOTek digital oscilloscope portable logic analyzer is a 5-trace 4-channel digital oscilloscope for common electronic engineering tasks. Its CPU is based on ARM Cortex M3, adopting FPGA to manage the control & data buffering of ADC. A built-in 8 MB USB disk enables users to store waveforms & upgrade firmware. It also provides 4 application areas, convenient for users to load & upgrade at most 4 kinds of application firmware.
