Superior RF and digital performance

Propsim aerospace channel emulation solution features a channel modeling interface

with up to eight channels and up to 160 MHz signal bandwidth. This is directly within

an RF input signal frequency range of 220 MHz to 6 GHz, making external RF down/

up conversion redundant. Systems operating on up to 27 GHz are supported with IF or

external RF down/up conversion. The solution provides 100 g acceleration emulation

capability and up to 1300 ms propagation delay.

GUI supporting file import from external tool

The graphical user interface of Propsim aerospace modeling tool enables you to gener-

ate, edit and visualize emulation models.

Open text-based file format

Keysight’s Propsim aerospace modeling tool supports any user-defined routes or

built-in functions for periodic models. The open text-based file format allows the

import of customer-specific radio channel and location parameters, such as satellite

orbital information or any airborne route information. The Propsim aerospace & satellite

modeling tool can take input in two different formats of channel model data (e.g. from

software simulation tools). This allows you to define and emulate the communications

links of flight routes or test the wireless connection on an aircraft with link emulations

based on virtual links or recorded link databases.

Propsim aerospace modeling tool enables you to create and edit different types of

channel models with periodic curves

– Coordinate-based model – you define coordinate points and gain values for the

transmitter, receiver and reflectors. Delay, range rate and Doppler parameters are

calculated from the movement between given coordinate points.

– Function-based model – Doppler is defined based on linear, sinusoidal or triangular

function. The delay is calculated from Doppler. You can define minimum and

maximum values for gain.

– Arbitrary model – Doppler, delay and gain values in time are included and the values

are given separately for the transmitter, receiver and reflectors.
