• Notes

• The SMG40 Stereo Generator is a compact stereo generator which provides a time-multiplexed composite signal conforming to the FCC and EBU standards for stereo broadcasting.

  The time-multiplex principle has been adopted in the SMG40 because of its advantages of which one of the most significant is the completely uniform handling of the left and right signals, which implies that minor amplitude- and phase-differences become less probable.

  The composite signal can be used in testing high-quality multiplex stereo decoders and in driving FM signal generators to full 75 kHz deviation.

  The SMG40 can be modulated either with the built-in, low distortion oscillator offering a choice of five fixed frequencies or from an external AF generator.

  The SMG40 is provided with the following modes: L & R, L = R, L = -R, L, R.

  The SMG40 has a preemphasis selector for 25 µs, 50 µs or 75 µs.

  Each solid state devive listed once only.
