Feature Description
Automatic Gain
Control The KST-2000A/B 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. This feature is provided for use
with Comtech EF Data SSPAs up to and including 40W.
Optional IF
Input/Output of 70 or
140 MHz Optional on ordering.
Redundancy
Controller (Built-in) Each KST-2000A/B converter unit contains the logic and switch drivers
necessary for redundant configurations when used with the RJU-2000.
Selectable Serial
Communication There are several selectable serial communications:
• EIA-232, EIA-485, or EIA-422 half-duplex
• 300 to 19200 baud rate
• 8N1, 7E2, and 7O2 (information bits, parity, stop bits)
Keypad/Display
An optional weatherproof keypad/display designed to control the KST-
2000A/B configuration parameters and to monitor the fault system.
L-Band Received
Power Monitor Output An isolated output covers the 950 to 1700 MHz downlink bands.
Internal or External
Reference The KST-2000A/B’s internal reference may be locked to an external
standard at 5 or 10 MHz in order to reduce the system frequency errors
to that set by the external reference; or the high-stability, electrically and
mechanically tunable internal reference may be used.
External LED
Indicators for Power
On and Fault
Indication A GREEN LED indicates prime power ON when blinking and TX RF
power ON when steady. A RED LED indicates a summary fault.
Power Factor
Corrected Internal
Power Supply All KST-2000A/B power supplies have power factor corrected power
supplies and meet all CE Mark requirements.
Flexible HPA options The KST-2000A/B converter has built-in monitor and control circuitry and
functions that operate with the following equipment:
• KST-2000A/B product line SSPAs
• Selected other SSPAs
• Selected Traveling Wave Tube Amplifiers (TWTAs).
This flexibility enables adjusting the system’s power output to meet
application requirements by simply changing the HPA.
Industry Standards
Met • IESS 308 and IESS 309
• FCC radiated emissions requirements
• CE Mark
The KST-2000A/B system components are completely weatherproof
units designed for the harsh environments of antenna-mounted systems.
The system’s operating parameters can be monitored and controlled
using Windows™ based M&C software with a personal computer, a
keypad/display built into the KST-2000A/B, or a hand held KP-10 as
described in Chapter 3.
