The Agilent/Keysight 8750A is a storage normalizer accessory that extends the measurement capabilities of network and spectrum analyzers through digital trace storage, comparison, and normalization functions. It enables simultaneous display of stored and live traces—or two stored traces—on the analyzer display for precise side-by-side comparison. The instrument compensates for frequency response variations and systematic errors introduced by cables, adapters, and test sets, delivering accurate characterization of devices under test.
– Technical Specifications
Power Requirements: 100, 120, 220, or 240 Vac ±5%; 48 to 440 Hz; ≤30 VA (20 watts).
Physical Dimensions: 212 mm W × 88 mm H × 269 mm D (8.4 in × 3.5 in × 10.6 in).
Weight: 2.72 kg (6 lbs) net; 4.99 kg (11 lbs) shipping.
– Key Features
• Trace Storage and Normalization: Store reference traces from calibration procedures and overlay live measurements for direct gain and phase compensation across the frequency range of the connected analyzer.
• Dual Trace Display: View two traces simultaneously on the analyzer’s CRT—ideal for before/after comparisons or reference-versus-measurement workflows.
• External Recording Output: X-Y recorder interface for analog trace plotting.
• Display Control: Integrated blanking in/out signals for synchronized display management.
– Typical Applications
Network analyzer calibration and normalization workflows. Spectrum analyzer trace storage and comparison. Systematic error correction in RF measurement setups. Device characterization requiring reference-normalized measurements.
– Compatibility & Integration
The 8750A interfaces with Agilent/Keysight network and spectrum analyzers via dedicated interface boards: Network Analyzer Interface Board Assembly (HP 08750-60005) and Spectrum Analyzer Interface Board Assembly (HP 08750-60009). Both assemblies are included as standard accessories. External X-Y recorder outputs support standalone documentation of stored traces.
