Rigol Spectrum Analyzer DSA1030A 9Khz-3Ghz 8.5″ Tft 148Dbm (800X480)

The Rigol DSA1030A is a benchtop spectrum analyzer delivering RF measurement across 9 kHz to 3 GHz. Built on all-digital IF architecture, It has the stability and reliability demanded in demanding RF applications. The instrument achieves displayed average noise levels down to −148 dBm (with preamplifier, 10 Hz RBW) and frequency resolution to 1 Hz, enabling detection of weak signals across its full frequency span.

The 8.5-inch TFT-LCD widescreen display (800 × 480 resolution, 65,536 colors) presents spectral data with clarity across 601 display points in standard mode or 761 points in full-screen mode. Resolution bandwidth spans 10 Hz to 1 MHz in 1-3-10 sequence, accommodating both narrowband and wideband analysis.
