GSS6450 Record and Playback System

The GSS6450 captures real-world GNSS, cellular, and wideband RF signals across three independent ports for high-fidelity, repeatable playback in the lab.

Frequency range RF1 Lower L-band 1164-1300MHz, RF1 Upper L-band 1559-1610MHz, RF2 640-2400MHz, RF3 470-6000MHz
Supported standards Records GPS, GLONASS, Galileo, BeiDou, QZSS, SBAS, WiFi, Cellular Signals

Bring Real-World Signals into the Lab for Repeatable RF Testing

Field trials are expensive, slow, and impossible to repeat exactly. Portable analyzers solve this by capturing real-world radio frequency (RF) signals — global navigation satellite system (GNSS), cellular, and Wi-Fi — across three independent ports, then replaying them in the lab on demand. The GSS6450 Record and Playback System records at up to 80 MHz of bandwidth with 80 dB of dynamic range, monitors the RF environment in real time, and runs on battery power in a 2.2 kg portable case. Engineers can validate receivers, navigation systems, and connected devices against authentic signal conditions without returning to the field.

High-Fidelity Field Capture

Record multi-band GNSS, cellular, and Wi-Fi signals across three independent RF ports at up to 80 MHz bandwidth.

Repeatable Lab Replay

Play back captured environments as often as needed to validate receivers and devices under identical RF conditions.

Built-in Signal Monitoring

Use the integrated spectrum analyzer to inspect the RF environment in real time during recording and playback.

Lightweight and Field-Ready

Operate untethered in the field at 2.2 kg, then control the unit via touchscreen, Wi-Fi, or scripted automation.

Highlights

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.
  • 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
