Spectrum analyser platform extends to 3.2GHz and 7.5GHz

Two new high performance high frequency spectrum analysers have enhanced the Rigol Technologies DSA800 series platform. The DSA832 and DSA875 expand the family to 3.2GHz and 7.5 GHz respectively. The new instruments enable direct measurements of higher performance signals and systems.

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 more accurately analyse modulations and noise surrounding their signals of interest. This becomes important for debugging and immunity testing of transceiver systems.

The 7.5 GHz instrument enables engineers to investigate the 3rd harmonic of all of their critical 2.4 GHz applications. Additionally, resolution bandwidth settings down to 10 Hz mean more precise visualisation of low power RF signals. Whether debugging the RF transceiver set, designing layout and configuration changes to maximise efficiency, or testing a system in noisy environments the spectrum analysers will enable quick and easy identification and analysis of areas of concern.

The DSA832's expanded range (up to 3.2 GHz) enables more complete EMI test coverage than previous generations. With the EMI-DSA800 option users can enable the EMI RBW settings and the Quasi-Peak filter across the entire spectrum of interest for compliance and immunity testing.

It is also possible to 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 popular and rugged DSA800 platform, 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. Rigol will introduce a new EMI Test Software for Pre-Compliance tests during the next few weeks for a complete RF test offering.
