The TDS744 4 Channel Digitizing Oscilloscope has a bandwidth of 500MHz and a sample rate to 2 GS/s. The maximum record length is 50,000 points per channel. The instrument is fully programmable via GPIB (IEEE 488.2) and has GPIB, RS-232 and Centronics I/O ports. The TDS744 is a 500 MHz digital oscilloscope from Tektronix. Digital oscilloscopes make use of binary numbers that correspond to samples of the electronic equipment’s voltage. This is in contrast to analog oscilloscopes, which use continually varying voltages. Digital oscilloscopes use an analog-to-digital converter (ADC) to convert the voltages it measures into digital information.
