June 9, 2014. Rigol Technologies Inc. has announced its latest series of products: two new high-performance, high-frequency spectrum analyzers built on the DSA800 Series platform. The DSA832 and DSA875 expand the DSA800 Series spectrum-analyzer family to 3.2 and 7.5 GHz, respectively.
For design and development implementing Wi-Fi, Bluetooth, and other RF standards, the SSB phase noise down as low as -98 dBc/Hz at a 10-kHz offset empowers engineers to analyze modulations and noise surrounding their signals of interest. The 7.5-GHz instrument enables engineers to investigate the 3rd harmonic of all of critical 2.4-GHz applications. Additionally, resolution bandwidth settings down to 10 Hz enable precise visualization of low-power RF signals. Whether engineers are still debugging their RF transceiver set, designing layout and configuration changes to maximize efficiency, or testing their systems in noisy environments, the DSA800 Series spectrum analyzers will help them identify and analyze areas of concern.
Bob Bluhm, Rigol vice president, explained further, “The ability to make measurements at 7.5 GHz is a critical addition to our expanding product portfolio, because 2.4-GHz wireless design and development continues to expand into new product categories, both consumer and industrial. To design robust communication into their projects, the engineers need access to just beyond the 3rd harmonic at 7.2 GHz to get a complete understanding of the design tradeoffs and signal fidelity issues they need to deal with every day.”
The DSA832's expanded range (up to 3.2 GHz) enables complete EMI test coverage. With the EMI-DSA800 option you can enable the EMI RBW settings and the Quasi-Peak filter across the entire spectrum of interest for compliance and immunity testing. Users can find and evaluate even extremely low power issues with the preamplifier option (PA-DSA832 or PA-DSA875). Using the preamplifier, the displayed average noise level (DANL) normalized to 1 Hz is specified as low as -161 dBm (typical) from 5 MHz all the way to 3.2 GHz.
Built on the rugged DSA800 platform, the new DSA832 and DSA875 have a broad set of features and options including a VSWR measurement toolkit for configuring and evaluating antennas as well as an advanced measurement kit (DSA800-AMK) that enables additional measurement functions including channel boundaries and signal to noise ratio factors. New accessories include the 8-GHz VSWR bridge or directional coupler (VB1080) as well as new accessory packs for 75-Ω work (RF CATV Kit) and attenuator sets for higher power work.
