The internal pulse frequency source is crystal stabilized and uses a digitally controlled frequency divider to select frequencies. Two receiver damping settings optimized for very high frequency transducers are available. All attenuators use relay switched resistors for accuracy and stability. The user interface at the controlling computer is the same, whichever link is used. The command structure for the 5910PR involves commands which execute individually to set the pulser and receiver parameters.
Local control is accomplished by means of a front panel touch keypad.
All instrument settings may be viewed locally through an eight line by forty character LCD display that features adjustable contrast and back lighting. 400MHz RF bandwidth for optimized high frequency performance. Local keyboard control also allows independent operation. 40 stored setups. 50dB typical isolation at 400MHz in through-transmission mode.
