  Description

The B&K 2640 hand held RF Field Strength Meter has a measurable frequency range of 100kHz to 2000MHz and is battery operated. It is optimized to analyze signals from many different sources for multiple applications. The characteristic of frequency response of the B&K Precision 2640 is calculated by memorized calculation data from a “look up table”, and so it enables the 2640 to measure accurate levels and makes easy analysis of a wide range of frequency bands.

The 2640 provides various functions all with 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, Paging Systems, CB Paging, Cable and Satellite TV Systems as well as antenna site measurements and maintenance. The B&K 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.

Functions:

Spectrum: Peak Search, Marker to Center, Channel Power Function

Internal Attn.: The input range can be extended by internal Max 10 dB Attn. function.

Sweep Mode: Single Run, Free Run, Squelch Run Selectable

Squelch Function: The Squelch Level may be adjusted to any value from the reference level to Full Scale.

Copy Function: The Copy Set mode allows the contents of the Channels edit Setup and Data memories to be copied to an external device. Data may also be written into these memories from external device.
