WAVETEK 25 Function Generator/Counter

Features

Model 25's represents the state-of-the-art in 5MHz analog function generators.

Exceptional waveform quality.

The Model 25 provides very high waveform quality under all conditions. That means low sinewave distortion, low aberration triangle waves and fast-edged square waves with low overshoot.

Variable symmetry pulses and ramps.

The Model 25 provides bidirectional variable symmetry from 1:9 to 9:1 that is independent of frequency setting.

Wide range level control.

The Model 25 provides a main output with a maximum emf of 10V pk-pk from a 50 ohm or 600 ohm source.

Wide frequency sweep range.

Each range can be swept (Linear or logarithmic) by at least 1000:1 either manually, via the external input, or using the built-in sweep generator.

Frequency locking for ultra stability.

The Model 25 includes a digital frequency locking system that gives it a level of frequency stability that cannot be matched by conventional analog function generators.

Amplitude modulation for extra versatility.

The Model 25 also incorporates comprehensive AM facilities. The modulation can be external or internal (via a 400Hz internal generator) with modulation levels fully variable between 0% and 100%.

Dual digital displays for precision & convenience.

The Model 25 incorporates a large dual section digital display. Unlike competitive products the display provides a readout not just of frequency, but of amplitude or offset simultaneously.

External counter with seven digit resolution.

The Model 25 has an external counter mode which utilizes the full width of the display to provide up to seven digits of resolution. The frequency range is from 5Hz to 20MHz and the input sensitivity is better than 50mV rms.
