R&S®XK2900L HF Transceiver

The R&S^®XK2900L 1000 W HF transceiver is available as a desktop version or as a sturdy rackmount for the 1.5 MHz to 30 MHz. frequency range. It can be operated locally as well as remotely via an integrated, multistandard serial interface. For the local mode, a user-friendly, large backlit LC display is provided on the front panel of the R&S^®GX2900L receiver/exciter, delivering a bright picture together with function-assigned softkeys. These control elements allow programming of approx. 400 channels as well as the complete operation and 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 used:

• R&S^®GP2000 remote control processor
• R&S^®GB2000 remote control unit
• Terminal
• PC with RS-232-C/RS-485 interface

Two units can be simultaneously connected. The associated software (R&S^®Series 2000S) is supplied on a CD-ROM.

The basic R&S^®XK2900L model consists of the following:

• R&S^®GX2900L receiver/exciter
• R&S^®VK2900 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.

For AC operation of the transceiver, the R&S^®IN4190 AC power supply is used, which can be set to different input voltages as well as to single- or threephase networks. Moreover, a 24 V standby battery can be connected to the R&S^®IN4190, for interrupt-free operation of the transceiver at reduced RF power (100 W) in the event of a power failure.

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, HF modem, detached duplex or emergency receiver (GMDSS). Up to four options can be inserted into the free slots at the rear.

The 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^®IN4190.
