  • Page 9: Chapter 2 General Description

    Control Device: Generates a DC voltage offset (bias) that is superimposed on the signal for driving the shaker. For Type 1056 to work properly, you are required to use a power amplifier capable of processing DC voltage signals, such as Brüel & Kjær Power Amplifier Types 2732, 2720 and 2721.

  • Page 10: Basic Operation

    Mains Input: Input socket accepting a female connector. Mains voltage supplied via Power Amplifier Type 2732, 2720 or 2721 Type 1056 has to be inserted into the signal path between the generator and the power amplifier – see Chapter 4 for examples of typical setups.
  • Page 11 CHAPTER 2 General Description Controls Press Start to start the device. The shaker head will move into its zero position. Press Stop to stop the device. The signal inputs will be interrupted and the shaker will move into its position of rest. Use the Stiffness control keys to control speed (stiffness) of the device.
