B + K Precision Introduces High Quality, 3.5Ghz Frequency Counter
YORBA LINDA, Calif. January 28, 2005 - B&K Precision Corporation, one of the industry's leading suppliers of test and measurement products, today announced the immediate availability of the Model 1856D, a high-quality, lightweight frequency counter capable of frequency measurements from 0.1Hz to 3.5GHz to its expanding line of cost-effective instruments. This compact, versatile, easy to use, highly reliable counter is ideal for a broad spectrum of laboratory and service applications. The Model 1856D Frequency Counter offers excellent performance and flexibility and its exceptional accuracy, sensitivity and range make this an extremely valuable instrument for scientists, engineers, and communications technicians. And at a suggested retail price range of $499, it is one of the most aggressively priced counters on the market today.
Outstanding features of the Model 1856D include:
o RPM (Revolutions per Minute) measuring function
o External frequency standard input with 9 digit LED display
o Attenuator
o Period
o Total
o Low Pass Filter
o Line Filter
The Model 1856D features a special 50 ohm-terminated input for use in high frequency VHF/UHF/microwave/cellular telephone systems, as well as a standard 1 Mohm input for frequency measurements up to 100MHz. The counter utilizes a nine-digit display, which provides up to 10nHz resolution to 3.5GHz, 1Hz resolution to 100MHz, and 0.1Hz resolution to 10MHz.
In Period Mode, the unit measures the period required (in microseconds) for one cycle, over the range of 5Hz to 3.5MHz. 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.
Front panel push-button switches select the Operating Mode and one of four decades of resolution. Easy-to-interpret readouts are provided by large, bright digits, automatic decimal point placement, leading zero blanking, and LED display of proper measurement units. Over range and GATE function (indication of a measurement in progress) are also shown on front panel indicators.
A front panel HOLD switch is provided which "freezes" 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 X10 attenuator and selectable 100KHz 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 10MHz time base is generated by a temperature-compensated crystal oscillator (TCXO) for exceptional stability with regard to temperature (+/- 1ppm, 0°C to 40°C), and line voltage variation (0.lppm for +/- 10% variation). Other features include universal ac capability, a multi-position carrying handle/tilt stand for portability, and internal RF shielding.
Measuring a compact 3.5" high by 10.6" deep by 9.4" wide, the lightweight (5.5 Ibs) Model 1856D Frequency Counter comes complete operating manual and line cord. It is priced at $499, quantity one and is available for immediate delivery.
