This unit
The Keysight 70903A is an IF section module that extends the frequency analysis capabilities of 70000 series spectrum analyzers through signal downconversion. This 1/8-width module processes a 21.4 MHz intermediate frequency signal and outputs a detected video signal, enabling measurements across lower frequency bands than the base analyzer supports alone.
Technical Specifications
- Module Type: IF Section Module
- IF Signal Processing: 21.4 MHz
- Resolution Bandwidth: 100 kHz to 3 MHz
- Output: Detected video signal
- Form Factor: 1/8-width module
Key Features
- Downconverter functionality for extended frequency range analysis
- Compact 1/8-width module design for integration into modular systems
- Processes intermediate frequency signals with selectable resolution bandwidths from 100 kHz to 3 MHz
- Produces detected video output for direct measurement and display
Typical Applications
- Signal analysis in lower frequency bands
- Expanding measurement capabilities of existing Keysight 70000 series analyzers
- Applications requiring 21.4 MHz IF signal processing
- Specialized signal analysis tasks beyond native analyzer frequency range
Compatibility & Integration The 70903A integrates within the Keysight 70000 Modular Measurement Systems architecture. Installation requires a spectrum analyzer RF section or external mixer interface module. The module works in conjunction with system masters such as the HP 70900A Local Oscillator. Complete installation and verification procedures are documented in the HP 70903A Installation and Verification Manual and the 70903A IF Section Installation and Verification Manual, which provide detailed specifications, setup guidance, and troubleshooting information.
