Data Sheet

Frequency Counters

Models 1823A, 1856D

Model 1823A

Model 1856D

The 1823A and 1856D are reciprocal 2.4 GHz

and 3.5 GHz frequency counters that are

microprocessor controlled. Their LED displays

can provide up to nine digits of resolution using

an external time base with a 10 s gate time. The

high accuracy, sensitivity, and versatility of these

counters make them an extremely valuable

instrument to scientists, engineers, and

communications technicians for a broad spectrum

of laboratory and service applications.
