The R&S®XK2500L 500 W HF transceiver is available as a desktop version or as a sturdy rackmount for the frequency range 1.5 MHz to 30 MHz. It can be operated
locally as well as remotely via an integrated, multistandard serial interface. For the local mode, a user-friendly, large LCD display with backlighting is provided on the front panel of the R&S®GX2900L receiver/exciter, i.e. a bright display together with function-assigned softkeys. These control elements allow the complete operation, programming of approx. 400 channels as well as configuration of the transceiver via user-specific menus (incorporated as firmware).
All settings of the transceiver can be
effected via the RS-232-C/RS-485 interface
(integrated and configurable). The
following remote control units can be
R&S®GP2000 remote control
R&S®GB2000 remote control unit
Two units can be simultaneously
connected. The associated software
(R&S®XK2000S) is supplied on a 3.5" disk.
The R&S®XK2500L basic model consists
of the following:
R&S®VK2500 power amplifier
R&S®IN4190 AC power supply
The R&S®GX2900L comes with free slots
at the rear to take up user-specific interface
options for matching the system or
user units. ATUs are connected to the rear
AC supply operation of the transceiver is
effected by the R&S®IN4150 AC power supply which can be set to different input voltages
as well as to single- or three-phase
networks. Moreover, a 24 V standby battery
can be connected to the R&S®IN4150 AC supplying 24 V DC in the case of power
failure so that an interrupt-free operation
of the transceiver at reduced RF power
(100 W) is possible.
If the transceivers are operated in DATA mode, i.e. continuously at full transmit power, an integrated blower system, which is switched on automatically when required, ensures trouble-free continuous operation of the transceivers without overheating.
The R&S®GVxx, R&S®FK21xx, and R&S®GS21xx interface options that are plugged in at the rear of the
R&S®GX2900L receiver/exciter allow easy connection or matching to external options such as a system processor (PC), HF modem, telephone PABX, detached
duplex or emergency receiver (GMDSS). Up to four interface options can be inserted into the free slots at the rear.
Spacing/interconnections between units
The standard spacing between the R&S®GXxx, R&S®VKxx, and R&S®INxx units is determined by the internal interconnecting cables. The spacing is 5 m
between the R&S®GX2900L and R&S®VK2500/2900 and 1 m between the R&S®VKxx and R&S®IN2500/2900.
