Revision 2 Introduction MN/KST2000L.IOM Description The KST-2000L satellite terminal system is a high-performance transceiver designed for single-thread configuration outdoor operation. The unit transmits in Ku-Band and receives in L-Band. The converter unit controls external High Power Amplifiers (HPAs). Automatic Gain Control (AGC) from the converter input to the HPA output assures power output stability over varying conditions.
Parameter Description Automatic Gain Control The KST-2000L incorporates a closed loop control system that maintains the system’s conversion gain (as measured from the IF input to the Ku-Band SSPA output) at the user’s preset value despite the effects of temperature, aging, and cable loss.

3.2.1.10 LNB Connections Note: The power supply for the LNB can be supplied by the KST-2000L. The RF input of the LNB is a WR-75 waveguide flange. The RF OUT/REF/PWR IN connector of the LNB is a type N, 50Ω connector. It supplies the block-converted output of 950 to 1700 MHz.
Chapter 4. OPERATION This chapter describes the procedures for initial testing of a KST-2000L system, and de- scribes each major system function. Initial Setup This section details the procedures necessary to laboratory test a KST-2000L system for the first time. Refer to Figure 4-1 for system setup.
Note: Ensure that the termination selected for the HPA output is sized to handle the HPA output power. Apply power to the KST-2000L. After a few seconds ensure that the green TX ON LED is flashing, and the fault LED is extinguished. Refer to Section 4 if this is not the case.

The 72 MHz VCXO is phase locked to the 10 MHz reference. The 72 MHz output of the VCXO is amplified and distributed throughout the KST-2000L to provide a reference fre- quency for the up converter and portions of the down converter.
Satellite Terminal System Revision 2 Operation MN/KST2000L.IOM Up Converter Description The up converter accepts a 70 MHz (140 MHz) IF input signal and translates it to an out- put frequency in the range of 13.750 to 14.500 GHz. The up converter consists of two modules: the IF to S-Band module and the S to Ku-Band module.

S to Ku-Band Up Converter Module The S to Ku-Band up converter module (Figure 4-4) performs block up conversion of the 2,330 to 3,080 MHz signal input to an output in the range of 13.750 to 14.500 GHz.
MN/KST2000L.IOM Automatic Gain Control (AGC) The KST-2000L incorporates a closed-loop Automatic Gain Control (AGC) function that maintains the system gain, as measured from the TX IF input to the Ku-Band output of the SSPA, at the user’s preset value despite the effects of aging, operating temperature, or cabling loss.
Satellite Terminal System Revision 2 Operation MN/KST2000L.IOM 4.5.2 Fault and Error Response Table 4-1 shows how the AGC system reacts to power outages, system faults and opera- tion outside the specified limits. Table 4-1. AGC Fault and Error Response Problem Response/Notes If the transceiver prime power fails The UCA value is effect prior to the failure is restored on power up.

AGC Operating Region 4.5.3 Manual Gain Operation With AGC disabled, the closed loop control of the uplink path is disabled. The SSPA saturation, INSUFFICIENT INPUT POWER, EXCESSIVE INPUT POWER, and LOOP faults are not monitored or reported as faults.
The TX ON indicator is green when illuminated, and the FAULT indicator is red. When prime power is applied to the KST-2000L and the HPA is transmitting power, the TX ON indicator is a steady green. The indicator flashes when prime power is applied but the HPA is not transmitting.

Chapter 7. TERMINAL MODE COMMANDS This chapter defines the protocol and command structure for remote control and status monitoring of the KST-2000L in the terminal mode of the Windows™ based M&C remote control software and on the KP-10 keypad. General Remote control and status information are transferred via a EIA-485, EIA-422 or EIA-232C serial communications link.
7.2.2 Device Address The device address is the address of the KST-2000L which is designated to receive a transmitted command or which is responding to a command. Valid device addresses are 1 to 3 characters long and in the range of 0 to 255. Address 0 is reserved as a global address, which simultaneously addresses all devices on a given communications link.
7.2.3 Command/Response The command/response portion of the message contains a variable length character sequence, which conveys command and response data. If a KST-2000L receives a message addressed to it, which does not match the established protocol or can not be implemented, a negative acknowledgement message is sent in response.
Satellite Terminal System Revision 2 Terminal Mode Commands MN/KST2000L.IOM System Configuration Commands The commands and responses for setting the basic system parameters of uplink and downlink frequency and attenuation, for making an adjustment on the internal reference, and for disabling the RF output.
