Leakage tester The leakage tester is mainly composed of DSP28335, FPDA, AD9954 digital frequency module, Main core parts: DSP28335 chip DSP28335 uses 32-bit floating point numbers and a main frequency of 150MHz. The practical development board adopts the core board and split mode. DSP28335 has 34k*16-bit single-cycle single-access random access memory SRAM, which is divided into 10 blocks, respectively M0, M1, L0-L7. There are also 256k*16-bit embedded FLASH memory and 1k*16-bit one-time editable EEPROM memory, which are protected by user passwords. AD9954 digital frequency module: using advanced technology, built-in a high-performance DAC, forming a complete digital programming, high-frequency synthesizer can generate up to 150MHz agile analog output sine wave. It can realize fast frequency hopping, and also has precise frequency adjustment (0.01Hz) and phase harmonics (0.022 degree interval) with a default program of 1Hz. The device has built-in static RAM, supports scanning functions in multiple modes, and supports user-defined linear scanning working mode.
