Data Sheet

Model 2658

Handheld 8.5GHz
Spectrum Analyzer

2658 is a handheld spectrum analyzer ideal for the evaluation of W-CDMA, CDMA,
GSM, PDC, PHS, Wireless LAN, 802.11 and Bluetooth systems. It was designed to
be the most cost effective spectrum analyzer for quick and easy high-precision signal
measurements.

- Measuring frequency range from 50KHz to 8.5GHz

- Auto tuning function

- Channel power measurements

- Adjacent channel power measurements

- Occupied bandwidth measurements

- Electric field strength measurements

- Magnetic field strength measurements
