ASLE-140-36D Image

The ASLE-140-36D from Polaris is an Advanced Satellite Link Emulator for geostationary satellite testing. It operates at a frequency of 140 MHz and has a bandwidth of more than 36 MHz. This link emulator provides accurate simulation of propagation delay, path loss, and Doppler frequency shift for closed-loop testing of geostationary satellites and earth station terminals. It has an attenuation range of up to 40 dB with a step size of 0.5 dB, and a Doppler shift range from -3 MHz to +3 MHz with a step size of 1 Hz.

The ASLE-140-36D has spurious levels of less than -45 dBc and a noise floor of up to -125 dBc/Hz. It has USB, RS-232, or RS-422/485 interfaces for remote control and a VFD front panel for local control. This link emulator is available in a benchtop enclosure that measures 19.00 x 5.25 x 21.00 inches and is ideal for UAV tests, earth terminal tests, mobile transceiver tests, VSAT tests, satellite modem tests, and satellite system integration test bed applications.
