  BNC output connector.
• Pink noise generator (also called frequency inverter or noise 1/ ƒ):
• Amplitude potentiometer, range: ± 10 V.
  BNC output connector.
• Microphone Pre-Amplifier module:
  It adapts the microphone signal to be analyzed by the data
• acquisition system or by the speaker. Unit: ATENG 12353
  1/4’’ jack input connector for the microphone.
  BNC output connector.
• Microphone:
• Impedance: 500 W.
• Frequency response: 70 Hz to 14 KHz.
  1/4’’ jack connector.
• Power Amplifier module, including:
  BNC input connector.
  BNC output connector.
  Potentiometer to regulate the power amplifier gain.
• Speaker module:
• Impedance: 8 W.
• Nominal maximum power: 30 W.
• Frequency response: 100 Hz to 13 KHz.
• PC input/output module, including:
  Two BNC input connectors.
  Two BNC output connectors.
  SCSI connector to the data acquisition board (to be placed in the computer).
  Possibility of working simultaneously with two external signals, facilitating operations that require more
  than one signal.
  Moreover, it is possible to generate different waveforms by the software and send them to the outputs
  of the unit.
  These signals can be visualized by an external oscilloscope or be listened by the speaker.
• The complete unit includes as well:
  Advanced Real-Time SCADA.
  Open Control + Multicontrol + Real-Time Control.
  Specialized Control Software based on LabVIEW.
  National Instruments Data Acquisition board (250 KS/s, kilo samples per second).
  Projector and/or electronic whiteboard compatibility allows the unit to be explained and
  demonstrated to an entire class at one time.
  Capable of doing applied research, real industrial simulation, training courses, etc.
  Remote operation and control by the user and remote control for technical support,
  are always included.
  Totally safe, utilizing 4 safety systems (Mechanical, Electrical, Electronic & Software).
  Designed and manufactured under several quality standards.
  Optional ICAI software to create, edit and carry out practical exercises, tests, exams,
  calculations, etc. Apart from monitoring user's knowledge and progress reached.
  This unit has been designed for future expansion and integration. A common expansion is
  the Scada-Net (ESN) System which enables multiple students to simultaneously
  operate many units in a network.
