Spectrum analyzers process "images"
-- Test & Measurement World, 2/6/2008 11:23:00 AM
Tektronix has added its DPX waveform image processor to the midrange line of RSA3000B real-time spectrum analyzers, making it possible for you to view the time-varying characteristics of RF signals. The RSA3000B series now lets you use the same color-graded persistence available on the company’s high-end spectrum analyzers and oscilloscopes.
With color-graded persistence, the RSA3000B can capture frequency-hopping signals such as Bluetooth and wireless LAN that can interfere with fixed-frequency signals. Other applications include detecting of illegal signals in a frequency band. The analyzer can process 48,000 waveforms/s. You can use the persistence mode to find interfering signals, then switch to frequency-domain triggering to capture, store, and analyze those signals.
The RSA3000B spectrum analyzers include compliance test support for ISO 18000-7, the standard that defines the air interface for RFID products. They also support compliance tests for ISO 15693-3, the standard for vicinity cards.
Base prices: $34,000–$53,000, depending on bandwidth. Tektronix, www.tektronix.com.
