The industry standard for MTS test and measurement. Certified compliance to BTSC standards can be used with any TV stereo generator. Provides four modes of operation. Maintains performance with varying temperature.

SRD-1 sets the standard for precision MTS test and measurement. The SRD-1 stereo reference decoder is the most accurate monitor on the market. It works with test equipment your station probably already owns, so it costs less than other, less precise test equipment.

Modulation Sciences has designed the SRD-1 with painstaking detail and individually calibrates each production model in basic units: voltage, frequency and phase. Verifying the original calibration requires only an audio oscillator, frequency counter and an accurate AC digital voltmeter.

Station personnel can calibrate the SRD-1 to verify its performance to BTSC Recommended Practices (Appendix D). When an SRD-1 is used to calibrate any television stereo generator, it provides traceability to the BTSC standards.
