Keysight GSS6450 GSS6450 Record and Playback System
Recording and playback
- Record across three independent RF ports covering GNSS L1/L2/L5/B3/E6, Wi-Fi, and LTE/cellular bands
- Maintain high frequency stability during record and playback using an oven-controlled oscillator
- Play back legacy recordings for regression and comparison testing
Automotive and integration
- Connect two High Speed CAN and CAN FD interfaces for automotive development workflows
- Import user-defined antenna patterns and vehicle dynamics data
Configuration and portability
- Reconfigure between runs using feature key licensing and field-upgradeable options
- Control the unit via touchscreen, Wi-Fi, web server, or scripted automation
- Deploy at 2.2 kg with a compact form factor for portable field collection
Keysight GSS6450 RF record and playback systems - formerly available through the Spirent positioning technology portfolio - capture real-world global navigation satellite system (GNSS), cellular, and wideband RF signals, enabling high-fidelity, repeatable lab-based testing.The GSS6450 captures real-world RF signals across three independent ports and plays them back in the lab with high dynamic range, wide bandwidth, and stable frequency reference - enabling repeatable, high-fidelity testing for positioning, navigation, and timing (PNT) applications.
