| B&K Precision 2640 is a hand held RF
Field Strength Meter, possessing a frequency ranging from 100kHz to
2000MHz. It is optimized to analyze signals from many different sources
for multiple applications. The characteristics of the frequency response
of the meter are calculated by memorized calculation data from a
preinstalled "look up table". These tools enables the 2640 to measure
accurate levels and makes easy analysis of a wide range of frequency
bands. BK 2640 provides various functions as well as a user-friendly
interface, which makes it easy and simple to use. The handheld RF Field
Strength Analyzer is ideal for users to test, install, and maintain
Mobile Telecommunications Systems, Cellular and Cordless Phone, CB
Paging, Paging Systems, Cable and Satellite TV Systems as well as
antenna site measurements and maintenance. The BK Precision 2640
supports RS 232C serial communication and has included GUI software. So,
user can control the 2640 easily after connecting the B&K Precision 2640
with a personal computer, and can utilize the analyzed data after
converting or saving numerical value or graph. |
