The SLE9125 from dBm Corporation is a Satellite Link Emulator with a center frequency of 140 MHz and a 1 dB RF bandwidth of 125 MHz. This advanced channel emulator can be configured with up to four independent simplex channels per chassis and has a maximum delay of 890 ms per channel. It has an in-band spurious suppression of -55 dBc and a VSWR of less than 1.5:1. The emulator has a delay slew rate of 0.3 ps/sec up to 20 us/ms and an relative accuracy of ±1 ns plus 10MHz reference. It has an attenuation range of 0-70 dB and a resolution of 0.10 dB. The emulator has a phase offset range of 0-180 degrees and an accuracy of less than 1 degree. It requires a primary power AC supply voltage of 90-264 V and has a maximum power consumption of 300 VA. This satellite link emulator features removable non-volatile memory to meet military/classified laboratory requirements and RF link emulation such as delay, Doppler, path loss, and phase shift frequency hopping. It weighs up to 47 lbs (4-channel) and measures 17 x 7.0 x 21 inches (W x H x D). The emulator is ideal for applications such as Earth terminal testing, satellite payload testing, satellite system integration test beds, mobile transceiver testing and UAV testing.
