Agilent/Keysight S8825A Digital Communication Analyzer

The Keysight S8825A Satellite and Aerospace Channel Emulation Toolset is a sophisticated solution designed for validating the performance of satellite, aerospace, and airborne radio systems under realistic and complex 3D propagation conditions. This toolset is built upon Keysight’s PROPSIM channel emulator platforms, specifically the F8800A F64 or F8820A FS16 models, and integrates an aerospace channel emulation engine (ACE). It is engineered to address the evolving demands of modern space applications, including wider signal bandwidths, higher frequencies, and advanced technologies like beamforming. The S8825A is particularly relevant for testing 5G Non-Terrestrial Networks (NTN), enabling the emulation of both terrestrial and space-based links within a single unit.

### Technical Specifications

**Core Functionality:**
* **Channel Emulation:** Provides realistic emulation of complex 3D wireless propagation conditions for satellite, aerospace, and airborne radio links.
* **5G NTN Support:** Specifically designed to support testing of 5G Non-Terrestrial Networks, facilitating the validation of satellite connections from mobile phones and end-to-end system testing.
* **High Velocity Environments:** Capable of creating test environments that emulate high Doppler frequencies and support long delays, which are critical for high-velocity aerospace and satellite link testing.
* **Mixed-Use Scenarios:** Enables the mixed utilization of cellular links with long-delay aerospace links, allowing for complex test scenarios including 5G NTN.

**Emulation Capabilities:**
* **Propagation Delay:** Supports propagation delay emulation of up to 1000 ms.
* **Doppler Effect:** Emulates Doppler phenomena for each channel’s path independently, maintaining phase continuity during dynamic delay variations. Doppler can be defined using linear, sinusoidal, or triangular functions.
* **Dynamic Multipath:** Offers dynamic multipath propagation capabilities, including dynamic mobile speed, multipath profile, and range delay.
* **Path Loss and Link Power Variations:** High dynamic range enables realistic path loss and link power variations.
* **Store-and-Forward Links:** Emulates store-and-forward type links.
* **Non-Linearities:** Emulates power amplifier non-linearity and phase noise of satellite hardware.
* **Interference:** Can include additive white Gaussian noise (AWGN) interference sources for each channel independently.

**RF Characteristics:**
* **RF Channel Count:** Supports up to 64 RF channels.
* **Signal Bandwidth:** Offers up to 1200 MHz signal bandwidth. The PROPSIM platforms supporting the S8825A offer signal bandwidths of 200 MHz / 1.6 GHz.
* **Frequency Range:** The core RF signal frequency range is 30 MHz to 6 GHz, with support for systems operating up to 100 GHz through external RF down/up conversion hardware. The supporting PROPSIM platforms have frequency ranges of 3 MHz – 7.25 GHz and 7.25 GHz – 18 GHz. The M1742A K-band Transceiver extends support to the 10 to 32 GHz range.

**Interfaces:**
* **Channel Modeling Interface:** Features a channel modeling interface.
* **Data Import:** Supports importing customer-specific radio channel and location parameters, including satellite orbital information or airborne route information, via an open text-based file format. It also supports importing data from third-party scenario tools and Keysight’s .aso file format.
* **Connectivity:** Enables interconnecting networks for full end-to-end system testing.

**Software and Control:**
* **Channel Studio:** Industry-leading Channel Studio software allows for the creation of customer-specific channel models with dynamic modeling capabilities.
* **Scenario Creation:** Users can create test scenarios using PROPSIM tools or import them from third-party tools. The ASO editor supports the creation of dynamic multipath scenarios and allows linking multiple radios into one scenario.
* **Visualization:** PROPSIM aerospace channel emulation engine enables the creation and illustration of user-defined emulation models, visualizing links between transceivers and receivers.

### Physical

* **Modular Design:** Combines a terrestrial channel emulator with a satellite channel emulator into a single, compact unit.

### Compatibility

* **PROPSIM Platform Integration:** Based on Keysight’s F8800A F64 or F8820A FS16 PROPSIM channel emulator platforms.
* **K-band Transceiver:** Compatible with the M1742A K-band Transceiver for extended frequency range support.
* **UXM and WaveJudge:** Can be utilized with Keysight’s UXM network emulation products and WaveJudge wireless analyzers for 5G NTN testing.
* **AGI Systems Toolkit (STK):** Seamless integration with AGI systems toolkit (STK) is supported.
