  • Notes

  • The BWD 141 Audio Oscillator is an all-silicon Solid-State Sine and Square Wave Generator powered by self-contained dry batteries (276-P) with 2 optional mains power packs available.

    1. Mains power pack.
    2. NI-CAD battery and mains charger.

    The wide frequency range of 1 Hz to 1 MHz together with its output attenuator and level control makes it suitable for both bench and field work.

    A balanced output is available by connecting a centre tapped resistor across the output terminals. Sine or Square Wove output is available by switch selection.
