The Agilent/Keysight 8750A Storage Normalizer augments network and spectrum analyzer measurements through digital storage and normalization. It compensates for systematic errors—gain and phase variations introduced by test setups—to deliver faster, easier, and more accurate results. Trace data storage enables direct comparison with subsequent measurements for device matching and performance analysis. Frozen traces simplify CRT photography and X-Y recorder output.
Technical Specifications
Memory and Display Resolution
• Two display memories: 256 data points per memory (0.4% of full scale, 8-bit word)
• Vertical resolution: 9-bit (0.2% of full scale) with 50% non-viewable overrange capability above and below full screen
Analog Inputs
• Horizontal input (Network Analyzer): 0 to 10 V nominal, ±0.5 V offset
• Adjustable gain for 6 to 15 V sweep ramp accommodation
• Vertical input offset control for adjustment
X-Y Recorder Outputs
• Horizontal accuracy: 0 V within 20 mV of zero reference; full scale within 43% of full scale reference
• Vertical accuracy: full scale within ±3% of full scale reference
• Pen lift output: 0 V minimum to 20 V maximum
• Blanking output (blanked): High at typically 3.5 V (4 mA max.) or Low at typically 0.4 V (10 mA max.); unblanked High at typically 3.5 V (0.3 mA max.)
– Key Features
• Overrange capability for storing and normalizing traces exceeding full scale
• Slotted sweep input gain control for horizontal input adjustment
• Digital storage with high vertical resolution enables precise error compensation
– Typical Applications
• Systematic error removal from network and spectrum analyzer measurements
• Device characterization and matching through stored trace comparison
• CRT documentation and analog recorder output for measurement archiving
– Compatibility & Integration
The 8750A interfaces with multiple analyzer platforms via dedicated assemblies: Network Analyzer Interface Board (HP 08750-60005), Spectrum Analyzer Interface Board (HP 08750-60009), and Option 004 for Model 8754A integration (HP 08750-6031). A 60 cm normalizer interconnect cable provides direct connection to compatible HP oscilloscopes, network analyzers, and spectrum analyzers. Option 001 BNC Interface Adapter Cable (HP 08750-60035) substitutes the standard cable for oscilloscope compatibility with HP 140T or 141T display sections. X, Y, and PEN connectors support X-Y recorder output.
