To be able to develop electronics it is not necessary to have a lot of fancy instruments. I started out having only 1 multimeter.\r\n\r\nThis lasted for over 7 years, but the need for debugging facilities with an oscilloscope got higher.\r\n\r\nIn year 2000 I bought an old 2 channel analog 20MHz oscilloscope without storage. It was suddenly an ease to debug my software an all my PWM projects.\r\n\r\n\r\n\r\nI had this scope for 6 years, but sold it after buying a brand new Tektronics TDS 2004 60MHz 4channel DSO (Digital Storage Oscilloscope). Wauw what an instrument!\r\n
Even though I have a very excellent oscilloscope it still misses the feature when measuring timing and signals on serial and parallel BUS data. For that purpose I bought a PC logic analyzer with 32 Channels + 2 Clk channels. It has 2K memory and a interpreter for SPI, I2C and RS232 protocol.
\r\n\r\n\r\n\r\n\r\nBeing able to measure input is always nice, but being able to create an simulate signals is almost just as important.\r\n\r\nThat’s why I have a function generator.\r\n\r\n\r\n\r\nWhat is a lab without power supplies?\r\n\r\nFirst a simple 3x5V made out of 3xLM7805 1Amp. voltage regulators.\r\n\r\n\r\n\r\nThen an adjustable voltage regulator with 2 independent sources.\r\n\r\n\r\n\r\nAbove PSU is made upon an Op-AMP with below schematic:\r\n\r\n\r\n\r\nFinally I have an evil power PSU delivering from 1.4V-16V and 40Amps!\r\n\r\n\r\n\r\nAnd then the more simple instruments:\r\n\r\n\r\n\r\n \r\n\r\n
