The maximum frequency of 7.5 GHz for the DSA875 allows developers to investigate the third harmonic of 2.4 GHz applications - the most important frequency bands for both WiFi and Bluetooth applications. Resolution bandwidth settings down to 10 Hz translate into extremely precise visualisation of low-power RF signals; features like an SSB phase noise of -98 dBc/Hz at 10 kHz offset enable developers to accurately analyse modulation quality and the noise surrounding their signal of interest. All these properties facilitate debugging and immunity testing of RF systems.
While Rigol's popular existing model DSA815 is used typically for precompliance testing, the DSA832's expanded range of up to 3.2 GHz enables more complete EMI test coverage. With the EMI-DSA800 option, engineers can enable the EMI RBW settings and the quasi-peak filter across the entire spectrum of interest for compliance and immunity testing. The preamplifier option (PA-DSA832 or PA-DSA875) enables them to identify and evaluate even extremely low power issues. With this option, the displayed average noise level (DANL) normalized to 1 Hz is specified as low as -161 dBm (typical) from 5 MHz to 3.2 GHz.
Built on Rigol's well-established DSA800 platform, the DSA832 and DSA875 offer 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 also announced to introduce a new EMI Test Software for Pre-Compliance tests during the next few weeks for a complete RF test offering.
