9 kHz–2.9 GHz DVB-C QAM RF Spectrum Analyzer HP Agilent 8594Q

This pre-owned Agilent 8594Q is purpose-built for CATV and DVB-C maintenance, combining a 9 kHz–2.9 GHz spectrum analyzer with on-board 16/64/256-QAM demodulation. Native support for 2, 4 and 8 MHz channel bandwidths (plus 6 MHz with option J91) and a –135 dBm noise floor let technicians verify carrier flatness, MER and constellation quality without external gear.

The rugged 4-slot chassis remains fully option-upgradeable, while purchasing refurbished trims capital budgets and lead-time; instruments ship with fresh ISO-17025 calibration and verified firmware, delivering Agilent accuracy for field service or head-end QA at a fraction of new cost.
