Description of Signal Analyzer Keithley 2820

Vector Signal Analysis Mode—The Model 2820 is designed to be combined with a variety of signal analysis personality options for testing to the most common wireless standards, such as GSM, EDGE, W-CDMA FDD, cdmaOne, cdma2000, 802.11 WLAN, and 802.16e mobile-WiMAX. A robust set of measurements, instrument settings, and test limits are customized for each of the various standards, saving instrument configuration time and minimizing the potential for operator error. For example, an ACPR measurement for each of the standards is part of the signal analysis personality option.

Keithley 2820

The Model 2820 RF Vector Signal Analyzer is a mid-performance test instrument designed for R&D and production testing of modern RF communications equipment and devices. This next-generation instrument combines state-of-the-art RF and digital signal processing (DSP) technology to measure RF test signals rapidly with high accuracy and excellent repeatability. Its compact half-rack enclosure and competitive pricing make it a cost-effective solution for many test applications. The Model 2820's DSP-based software-defined radio (SDR) architecture and 40MHz bandwidth ensure it has the capability to measure today's signals and also the flexibility to handle tomorrow's. Today's mobile phones are designed to connect to more types of devices than ever before, so they must integrate with a growing number of wireless standards. As new wireless standards emerge, the Model 2820 is engineered for easy upgrades, which extend its useful life and provide an ongoing return on investment far longer than traditional instruments.
