Economical spectrum analyzers tackle bandwidths to 3.2, 7.5 GHz

Using all-digital IF technology and available with or without a factory-installed tracking generator (TG), the DSA832 and DSA875 expand the DSA800 spectrum analyzer family from 1.5 GHz to 3.2 and 7.5 GHz, respectively, at a cost starting at less than $7,000. For design and development of systems using Wi-Fi, Bluetooth, and/or other RF standards, the instruments’ low single-sideband (SSB) phase noise (as low as -98 dBc/Hz at a 10 kHz offset) empowers engineers to more accurately analyze modulations and noise, and is important for debugging and immunity testing of transceiver systems. The 7.5-GHz DSA875 spectrum analyzer lets engineers investigate signal performance to the 3rd harmonic for 2.4-GHz applications. Additionally, resolution bandwidth settings down to 10 Hz mean more precise visualization of low power RF signals. Compared to the 1.5-GHz DSA815, the DSA832's expanded range of up to 3.2 GHz enables more complete EMI test coverage.

Preamplifier options (PA-DSA832 or PA-DSA875) help find and evaluate even extremely low power issues; 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. With the DSA800-EMI option, users can enable the EMI RBW settings and the Quasi-Peak filter across the entire spectrum of interest for compliance and immunity testing. Other features and options include a VSWR measurement toolkit (VSWR-DSA800) for configuring and evaluating antennas, as well as an advanced measurement kit (DSA800-AMK) that enables additional measurement functions including channel boundaries and SNR 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 including the RF Attenuator Kit which includes 6- and 10-dB attenuators or the model ATT03301H 30-dB high-power attenuator. Pricing begins at $6,499.
