The PSLE-L-10D from Polaris is a Satellite Link Emulator that is designed for geostationary satellites has a frequency range of 950-1450 MHz and an operating bandwidth of 10 MHz. This satellite link emulator has an attenuation of -40 dB and a phase noise range of -84 to -127 dBc/Hz. It has a spurious value of -45dBc and a return loss of less than -14 dB. The satellite link emulator has 14-bit ADC SNR which supports the RS-232/RS-485 and USB interfaces with an AC supply voltage of 90-240 V. It provides an accurate simulation of propagation delay, path loss, and doppler frequency shift for closed-loop testing of geostationary satellites and earth station terminals. This satellite link emulator measures 19 x 7 x 21 inches and is ideal for applications such as satellite modem tests, VSAT tests, satellite payload tests, UAV tests, earth terminal tests, satellite system integration test beds, and mobile transceiver tests.
