This unit
The Agilent/Keysight 853A is a spectrum analyzer mainframe that delivers digital display capabilities for signal and spectrum analysis measurements. It functions as a host platform for interchangeable spectrum analyzer plug-in modules, with a built-in microprocessor managing display operations and self-test routines. The instrument provides dual independently stored digital traces with maximum hold, digital averaging, and trace normalization processing to enhance measurement fidelity.
Available in portable and bench configurations, with optional rack-mount capability (Option 001), the 853A supports HP-IB connectivity for direct plotter control and limited remote programming of display and processing functions.
Technical Specifications
- Display: CRT monochrome with dual digital traces
- Display processing: maximum hold, digital averaging, trace normalization
- Power consumption: less than 200 VA with compatible plug-in analyzer
- Maximum safe input power: +20 dBm (100 mW, 2.24 Vrms)
- Maximum safe input voltage: ±30 Vdc or 30 V RMS (<100 Hz)
- Gain compression: typically <1 dB at -10 dBm with 0 dB input attenuation
- Average noise floor: <-107 dBm (10 kHz resolution bandwidth, 0 dB attenuation, maximum video filtering)
Key Features
- Portable mainframe with tilt-bail handle and protective front cover
- Bench or rack-mount configuration available
- Microprocessor-based control and self-test initiation from front panel
- HP-IB (IEEE-488) interface with direct plotter control without external controller
- Remote analyzer sweep initiation via HP-IB
- Dual voltage supply options: 100/120 Vac ±5% to 10% (48–440 Hz) or 220/240 Vac ±5% to 10% (48–66 Hz), single-phase
Compatibility & Integration The 853A mainframe accepts Agilent/Keysight spectrum analyzer plug-ins including the 8557A (0.01–350 MHz), 8558B, and 8559A (0.01–21 GHz). It is mechanically and electrically incompatible with HP 8550-series plug-ins outside this listed group. HP-IB connectivity enables direct plotter control and limited programming of display functions without requiring a system controller.
