Toellner 7741

The outstanding feature of the TOE 7741 power function generator is its high power output of over 63 W (with rectangular waveforms). This power is achieved at an output amplitude of 45 Vpp into 8 Ohm load. Since the output amplifier has an internal resistance of approx. 0 Ohm and is shielded by feedback voltage protection, any external voltages of up to 120 V will not destroy its output stage. Furthermore, all front-panel inputs and outputs are no-load and short-circuit proof. The frequency settings are made using a decade switch, the frequency dial and the frequency offset potentiometer. The latter allows frequency settings with a reproducibility of < 0.1 %.

The outstanding feature of this instrument is its frequency counter that can measure both internal and external signal frequencies. The counter has an LED display. Besides the basic sine, triangle and square functions, the instrument generates positive and negative pulses and bipolar DC voltage, and can also be used as a broadband power amplifier for the range DC up to 100 kHz.
