2.0 GHz Handheld RF Field Strength Meter
Model 2640
Cost effective RF field strength meter with basic spectrum analyzer function
The B&K Precision model 2640 is a battery operated, hand-held RF
Field Strength Meter capable of measuring RF levels and electric field
strength. The synthesizer-based design provides you with reliable
measurements across a wide reception range of 100KHz to
2000MHz, a remarkably low noise floor of -110 dBm to detect weak
signals and basic spectrum analyzer functionality. The 2640 provides
field technicians and engineers with a cost-effective measurement tool
for basic signal investigations at only a fraction of the cost of a
full-featured conventional spectrum analyzer.
The 2640’s user-friendly interface combined with convenient presets
such as predefined filter settings and other special functions (e.g.
squelch) commonly used in analog communication systems make the
2640 easy to use. The B&K Precision 2640 supports RS 232C serial
communication and includes software that can control the instrument
from a personal computer. The user can save the instrument’s
measurement data on the PC for further analysis.
The handheld RF Field Strength Analyzer is an ideal tool for field
testing, installing and maintaining Mobile Telecommunications systems
such as Cellular and Cordless Phone, CB Paging, Paging, Cable and
Satellite TV Systems as well as performing antenna site measurements
and maintenance.
