Rigol Technologies has released two new high performance, high frequency spectrum analyzers. The DSA832 and DSA875 spectrum analyzers expand the company’s DSA800 series to 3.2 and 7.5 GHz, respectively.
The 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 Ohm work (RF CATV Kit), and attenuator sets for higher power work including the RF Attenuator Kit which includes 6 and 10 dB attenuators or the model ATT03301H 30 dB high power attenuator.
For adhering to Wi-Fi, Bluetooth, and other RF standards, the SSB Phase Noise down as low as -98 dBc/Hz at a 10 KHz offset enables engineers to more accurately analyze modulations and noise surrounding their signals of interest. This becomes important for debugging and immunity testing of transceiver systems. Using the 7.5 GHz instrument, engineers can investigate the 3rd harmonic of all of their critical 2.4 GHz applications. Additionally, resolution bandwidth settings down to 10 Hz means more precise visualization of low power RF signals.
Using the instruments’ EMI-DSA800 option, designers can enable the EMI RBW settings and the Quasi-Peak filter across the entire spectrum of interest for compliance and immunity testing. In addition, the preamplifier option (PA-DSA832 or PA-DSA875), assists with finding and evaluating even extremely low power issues. With the preamplifier option, 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.
“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,” Bob Bluhm, vice president of Rigol Technologies, said. “To design robust communication into their projects, 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.”
