Overview
The function generators of the TOE 7700 range represent a series of completely novel design. In addition to the usual standard signal shapes including variable signal symmetry, this range is equipped with a lin/ log sweep oscillator which should satisfy the most demanding users. Continuous or triggered sweeping is selectable, the lower and upper sweep limits are of course separately adjustable, and the sweep frequencies are precisely displayed by an integral frequency counter. Many details reflect the latest advances in circuit technology: a wear-free spinwheel for adjusting the output frequency and sweep time, an internally or externally usable frequency counter that employs a reciprocal counting method, and sophisticated new switching techniques allow signal qualities that were previously unattainable.
All inputs and outputs are floating, with the most important ones arranged on the front panel for ease of operation. A wide frequency range, an outstanding processing quality, and the clear and balanced design of the control panel round off the concept of these function generators. The TOE 7706, TOE 7708 A and TOE 7711/7711 A models also offer signal triggering and gate mode. The TOE 7708 A and TOE 7711 A models are additionally able to work in amplitude modulation mode, resulting in a significantly wider range of application. The TOE 7711/7711 A microprocessorcontrolled synthesizers/function generators combine the variety of functions that characterize universal function generators with the stability of modern synthesizers. In PLL mode, the output frequency is controlled with crystal accuracy in the 10 Hz to 44 MHz range. The basic accuracy is 2 x 10-6 of the full-scale value, and the aging rate is only 2 ppm/year.
Special features - Frequency range 1 mHz to 44 MHz - Sweep, trigger, gate - Variable symmetry - Digital display of frequency, sweep, AC, DC - Amplitude modulation - Frequency counter up to 50 MHz
