The IEC High Power Signal Generator has now been designed in the small IEC housing with the sloping front panel. This instrument is very popular in schools and universities. Because of its high current output, it can run large speakers and other mechanical devices directly without an amplifier. Range 0.1Hz to 100kHz over 6 ranges by graduated knob. Output #1: 600ohm impedance, 0-10V peak. Output #2: 20 ohm impedance, output voltage adjustable 0-10V peak, output current limited at 0.5A. Selectable waveforms are: sine, triangular, square (+/- excursion), square (+ excursion only)
