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.
