The Tektronix SG5010 Programmable Oscillator generates a ultra-low distortion sine wave from 10Hz to 163.8kHz with less than 0.0008% THD. The THD is typically less than 0.0003% in the 20Hz to 20kHz range. The unit offers the full benefits of TM 5000 configurability, GPIB compatibility, and compliance with Tektronix Standard Codes and Formats. It generates five waveforms: sine wave, square wave, SMPTE/DIN intermodulation test signal, CCIF intermodulation test signal, and sine wave burst. All of these signals may be swept in frequency and amplitude.
