Special Features:

The universal counter timer is microprocessor controlled and is designed to be used under the direction of the slot 0 system resource manager of a vxibus compatible mainframe; conforms to vxibus system specification revision 1.2; no local control over this counter is possible; additional features include rise/fall a, pulse width a, phase a rel b, external frequency standard input, math function, averaging mode, 1 megohm or 50 ohm input impedances, and x1 or x10 input attenuation; peaksignal measurement from 50 hz to 20 mhz is 150 mv to 51 v peak to peak

Properties:

An instrument used to count the frequency of recurrent electronic events and display the count on the panel of the instrument in numeric form. May also include facilities for a readout printed on tape. May include facilities for a very accurate output which can be used as a secondary transfer standard. It can be used to measure frequency, period, time interval, phase angle, frequency ratio, and for multiple period averaging. See also counter, electronic, digital and indicator, digital display.
