Opis: 2.4GHz Frequency Counter
Informacje:
                                    The 2.4GHz Frequency Counter is a high quality, lightweight
counter capable of frequency measurements from 5 Hz to 2.4
GHz. The 2.4 GHz Frequency Counter feature a special 50 12 -
terminated input for use in high frequency
VHF/UHF/microwave/cellular telephone systems, as well as a
standard 1 M O input for frequency measurements to 100 MHz.
The counters utilize an eight-digit display which provides
up to 10 Hz resolution to 2.4 GHz (Channel B). 1 Hz
resolution to 100 MHz, and 0.1 Hz to 10 MHz (Channel A).
In period mode, the unit measures the period required (in
microseconds) for one cycle, over the range of 5 Hz to 2M
MHz. At low frequencies, much greater accuracy can be
achieved by period measurement than by frequency measurement.
Totalize mode permits counting of individual events. The
counting process can be gated, either manually by a front
panel switch, or by a gating signal applied to a rear panel
jack, for more exact electronic control.
Operating mode and one of four decades of resolution are
selected by front panel pushbutton switches.
Easy-to-interpret readouts are provided by large bright
digits, automatic decimal point placement, leading zero
blanking, and LED display of proper measurement units.
Overrange and GATE function (indication
of a measurement in progress) are also shown on front panel
indicators.
A front panel HOLD switch is provided which "freezed" the
display at the present reading, as well as a RESET button
which clears the counter display and initiates a new
measurement when released.
A selectable x 10 attenuator and selectable 100 kHz low-
pass filter are incorporated at the standard frequency input
jack, for lessened susceptibility to noise and (in low
frequency measurements) undesirable high frequency components.
The 10 MHz CH.A and 3.90625MHz CH.B time base is generated
by a crystal controlled oscillator for good stability with
regard to temperature ( ± 10 ppm, 0 °C to 40 ”C ) and Line
voltage variation ( + 1 ppm for 10% variation).
Other features include universal ac capability, a
multiposition carrying handle/tilt stand for portability,
and internal RF shielding.
The exceptional accuracy, sensitivity, and range of these
counters make them extremely valuable instruments for the
scientist, engineer, and communications technician.
