Method and apparatus for programmable and remote numeric control and calibration of electronic instrumentation

Electronic signal processing apparatus for processing analog signals comprising:

• memory means for storing digital data representing control settings of analog operational functions performed by the apparatus, and for storing digital data representing calibration factors for calibrating said analog operational functions;
• computing means coupled to the memory means for computing the numerical value of digital data representing operational control signals for controlling said analog operational functions as a mathematical function of corresponding control settings and calibration factors, and for storing the digital data representing said operational control signals in the memory means;
• and
• a control panel coupled to the memory and computing means having first input means mounted thereon manually operable for causing the computing means to compute incremented and decremented values of the digital data representing the control settings of the analog operational functions performed by the apparatus;
• control means coupled to the memory means and computing means for producing operational control signals in response to the digital data representing said operational control signals, and applying the operational control signals to the analog operational functions associated with each of the control settings and calibration factors for processing the analog signals;
• and
• the control panel further including display means for displaying the incremented or decremented value of the control settings to the user.
