Group: Counter
Description: 1GHz Multifunction Counter
Information:
                                    INTRODUCTION
The Elenco model F-1000 is a 10Hz to 1000MHz
multiple-function counter that features a temperature
control crystal oven for high accurate readings. Other
features are eight high brightness seven segment
LED display, low power consumption circuit design and full
input signal conditioning. The F-1000 is also
small in size and light weight for easy portability.
The model F-1000 has four functions in one. It is a 1000MHz
frequency counter with accuracy of
,3Hz/million per month. This accuracy is achieved because of
the temperature control crystal oven. It
also has a self-test function which allows checking the
output for proper operation. The third function is a
period measurement which allows you to measure time interval
between pulses. The fourth function is a
totalizer counter which allows you to count pulses. All
these functions are accomplished by a single LSI
integrated circuit. The input signal is AC or DC coupled and
can be conditioned by attenuation of the
signal.
The location of controls, indicators, connectors and other
information on this model is provided in this
manual. It is recommended that you read and understand all
information in this manual before attempting
to operate this instrument.
