Special Features:

Opt 003 is c channel which measures to 1.0 ghz for cw and pulsed rf signals as narrow as 60 ms; time interval to 100 ns, ti averaging to 10 ps, allows single period measurements via channel a for period a; allows frequencies to 100 mhz into both channel a and b for ratio a/b; provides the gated totalize function of a gated by b; provides a manually gated totalize mode of operation; input signal conditioning controls includes porm slope, porm 2.5 v dc trigger level, ac/dc coupling, separate/common switch, 100 khz channel a low pass filter; dynamic range: 30 mv to 5 v peak to peak, 0-10 mhz, 75 mv to 5 v peak to peak, 10 to 100 mhz; operating temperature: 0.0 deg. To 50.0 deg. Centigrade

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.
