Keithley 2800 Frequency Selective Power Meter

The Keithley 2800 Frequency Selective Power Meter delivers rapid, accurate RF power analysis for wireless communication systems and RF/microwave applications. Purpose-built for production test environments, it isolates and measures specific signals within complex spectral conditions—delivering measurement speeds up to four times faster than conventional spectrum analyzers. A complete CDMA primary channel measurement with adjacent and alternate channel spurious emissions transfers in less than 30ms. Designed for manufacturers of wireless phones and RFIC power amplifiers, the 2800 combines essential wireless test capabilities in a compact footprint optimized for automated test systems.
