Amitec Satellite Trainer STC10 Satellite Trainer is the first of its kind using actual techniques of satellite communication. It can uplink a given signal to a satellite link emulator, which can be stationed far away. The satellite will then re-transmit the same signal at a different frequency to a downlink station, which will receive the signal. Audio signal can be fed through a condenser microphone provided at Transmitter and reproduced on built-in loudspeaker at Receiver. Video signal can be sent from camera and viewed on a monitor provided with the system. Actual emulation of satellite communication link can be performed with emulation of path loss, link fail, frequency translation. * High frequency microwave operation * Emulation of path loss at uplink and downlink * Emulation of frequency translation * High RF output power and low noise * PLL synthesized frequency in Transmitter, Receiver and Satellite Emulator * Condenser microphone and speaker provided for audio link * Camera and monitor provided for video link * Satellite emulator has antennas, frequency transponder for communication link * 4 large 25cm Dish antennas provided for linear polarization study * C/N and S/N measurement facility * Transmit Audio, Video, Digital/analog data, PC data, Tone, Voice, function generator waveforms etc. * Separate Terminals provided for Different inputs * Receives & demodulates 3 Signals Amitec STC10 Technical Specifications Satellite Uplinking Transmitter Satellite Downlink Receiver Frequency : PLL with frequency selection switch & LED indication Spurious output : - 30 dB typical RF Output Z : 75 Ohms Unbalanced RF output level : +3 dBm nominal with wideband RF amplifier with no manual matching required Path Loss : Upto 35dB variable attenuation Audio 1 : Int. 1KHz sine wave / Ext Mic Ext.
