Audio Oscillator-100 Hz and 400 Hz

The RDL ST-OSC2B is a precision sine-wave audio oscillator that provides two single-tone oscillators at 100 Hz and 400 Hz. Its amplitude-stable design, precise user-adjustable levels, and two separate outputs from each oscillator make it a focused signal source for audio applications that require either or both specified frequencies.

Ideal Use Cases

The ST-OSC2B is suited to audio testing, setup, and integration tasks that call for repeatable 100 Hz or 400 Hz sine-wave signals. Because the module contains two single-tone oscillators, both frequencies are available from one model without changing the oscillator configuration. The separate outputs allow each oscillator signal to be directed to two destinations when the system design requires multiple signal paths.

This model is especially relevant when a fixed-frequency source is preferred over a broader variable-frequency generator. Its defined 100 Hz and 400 Hz tones keep the module centered on applications that specifically use those audio frequencies.

Why Choose This Model

The central advantage of the ST-OSC2B is its combination of two dedicated oscillators and multiple outputs. One oscillator supplies the 100 Hz tone, while the other supplies the 400 Hz tone. Each oscillator has two separate outputs, providing four oscillator outputs across the two fixed tones.

Precise user-adjustable levels allow the output levels to be set for the intended installation. The amplitude-stable oscillator design supports consistent sine-wave signal generation. Together, these features make the ST-OSC2B a practical choice when fixed tones, adjustable levels, and separate output paths are all required in the same module.

Installation and Integration

The module uses the RDL SupplyFlex power input configuration. The recommended power supplies are the PS-24AS for USA installations and the PS-24AX for international installations. A power supply is not included, so the appropriate recommended supply should be selected separately for the installation location.

During integration, the two outputs associated with each oscillator can be assigned according to the required signal routing. Output levels can then be adjusted by the user for the connected system. Additional installation information and product details are available in the ST-OSC2 specification sheet supplied by RDL.

No mounting method, module dimensions, connector types, output impedance, output range, or included accessories are specified in the supplied product data. Those details should be confirmed from the specification sheet before final system design or installation.

Performance Highlights

• Precision sine-wave audio signal generation
• Amplitude-stable oscillator design
• Two single-tone oscillators in one model
• Fixed 100 Hz and 400 Hz frequencies
• Precise user-adjustable levels
• Two separate outputs from each oscillator
• RDL SupplyFlex power input configuration

The dedicated oscillator arrangement keeps the two specified tones clearly defined. Rather than relying on one oscillator that must be switched between frequencies, the ST-OSC2B provides both single-tone oscillators within the same product. Its separate output arrangement also gives each frequency two available signal paths.

What Makes It Different

The ST-OSC2B distinguishes itself through a narrowly defined combination of frequencies and output structure. It is not presented as a general-purpose sweep generator or a continuously variable oscillator. Instead, it concentrates on precision 100 Hz and 400 Hz sine-wave signals, with adjustable levels and two outputs assigned to each oscillator.

This architecture is useful when a system design repeatedly calls for these two specific tones. The user does not need to select a frequency from an unspecified range, and the two-output-per-oscillator configuration reduces the need to treat one oscillator output as the only available signal path. The result is a purpose-built RDL module with a concise, clearly stated feature set.

Final Assessment

The RDL ST-OSC2B is a specialized audio oscillator for installations requiring precision 100 Hz and 400 Hz sine-wave signals. Its two single-tone oscillators, amplitude-stable operation, user-adjustable levels, and two separate outputs per oscillator provide a well-defined foundation for fixed-frequency audio signal work. Buyers should plan for a separately purchased PS-24AS or PS-24AX recommended power supply and consult the specification sheet for installation details not included in the available product data.
