RVFM Signal Generator and Amplifier

Very high bandwidth operational amplifiers are employed for better wave shape at high frequency available at high impedance output. The signal generator uses latest DDS technology to synthesise sine, rectangular and triangular waves with extremely high purity and accurate frequencies.

Two microprocessors are employed, one is a dedicated DDS microprocessor and the other is used for frequency tuning, frequency selection and other panel controls. Frequency readout is by a 3-digit, 7-segment LED display. Signals are generated using a 26.843MHz, 100ppm reference crystal.

• Very accurate frequency outputs, 0.01% in all ranges
• Frequency range of 0.1Hz to 99.9kHz in six decades
• Very robust
• Withstands prolonged output short circuit
• Suitable for Key Stage 3+ (age 11 and above)
