1. Explanation of symbols, Environment protection 2. Safety informations 1.2 Important informations Symbol Meaning 1.1 Explanation of symbols ► Instruction Warnings ➔ Reference to a position in the document Warnings are marked by a warning triangle. In addition, signal words indicate the nature and severity of the consequences if the measures to avert the hazard are not followed.
This device is NOT a TOY. It must not be handled by children or placed within reach of children or even been operated. The unit should only be opened or serviced by a qualified technician. This device generates high frequency energy. Use the device with due care regarding the system configuration. When connected to an antenna, this linear amplifier can generate high-frequency electromagnetic fields, which must be evaluated according to applicable national laws.
3. Control elements and connections 3.
3.2 Control elements and connections 1 Power switch On/Off (1) (main switch) This rocker switch switches the device on / off. 2 Touch screen - GUI This Touch screen controls the device in all operating states. Also you receive context-related information about the operating status of the device.
4. Preparing for operation 4.1 Unpacking ► After unpacking, inspect the device for shipping damages. ► Report any damage immediately to the delivering freight forwarder or dealer. Keep the shipping box. 4.2 Scope of delivery 1x 1x 1x 1x 1x RF2K-S Power Amplifier 120 V AC line cord 240 V AC line cord Short coaxial cable with 1x SMA connector (“Pigtail“) Micro SD-Card for operating system 4.7 Preparing LAN connection 4.
5. Using the device locally Indication area Frequency TRX 5.1 Turning device on ► Turn on the device using power switch On/Off (1).
5.2 User menu Switching areas Submenus (Settings / Antennas / Update / Calibration / VNC / Interface) Switching area Tuner Activates (“On“) / deactivates (“Off“) the antenna tuner ► Touch the switching area Menu. The Touch screen (2) changes to the user menu and displays the screen shown to the right. The following submenus can be selected: 5.2.1 Settings Personalization Text ► Click the text box, highlight and change the personalization text by using mouse and PC keyboard.
Sleep Timer ► The Sleep Timer is activated/deactivated by (multiple) touching this switching area (Sleep Timer activated “On“ / deactivated “Off“) Erase Memory Bank ► By clicking on one of the three circular fields, the contents of the corresponding Memory Bank are deleted. NOTE! Contents are deleted in any case and regardless of whether the corresponding memory bank is currently activated. Sleep Timer Duration ► By touching the switching areas “<“ or “>“ the Sleep Timer can be adjusted.
5.2.2 Antennas Name ANT 1 For each band an Antenna Socket can be assigned to, which is selected by default when changing bands. Name ANT 2 To assign an Antenna Socket to a band: Name ANT 4 Name ANT 3 ► Tap the circle field in the corresponding column/row. The circle field is now displayed in black and thus indicates the current antenna assignment for the respective band. ► Tap the switching area Save to store the selected assignments as the default when changing bands.
5.2.3 Updates ► Tap the switching area Update to start the update process. The graphical user interface (GUI) and the controller firmware are constantly being further developed. We therefore recommend that you check for available Updates from time to time. Software version GUI Software version Controller If the device is connected to the Internet, you can search here for updates for the graphical user interface (GUI) and the controller firmware of the PA.
5.2.4 Calibration Indication area Current This menu item is divided into 3 submenus: - Poti Config: Indication area operating data - Offset Calibration: Calibration of the internal power measurement - Output Power Calibration: Band specific power matching Poti Config Before the device can be used after installation, some necessary adjustment work must be carried out! The indication areas inform you about some of the relevant values in this context.
Offset Calibration The unavoidable frequency-dependent deviations of the linearity of the directional coupler used for internal power measurement can be minimized for each bandpass range. The adjustment should be carried out at an output power of 1 kW. Use your preferred reference wattmeter for the adjustment.
Output Power Calibration The output power generated at a given control power can be adjusted optionally within certain limits for each bandpass range. Switching area < (decrease value) Switching area > (increase value) The 6 m band requires a higher control power than the other frequency ranges and should therefore always be set to “100“. Indication area Band Selection of the bandpass range is done automatically during transmission. The detected band is highlighted.
5.2.5 VNC 5.2.6 Interface With a VNC (Virtual Network Computing) connection, the device can be remotely controlled and operated from any PC, tablet PC or even smartphone connected to the Internet or local network using VNC software (remote operation). IIn future software versions the data connection between control transmitter/transceiver and PA will be configured in this screen mask. This part of the firmware is currently still under development.
6. Antenna tuner 6.1. Operation The LC network in a antenna tuner is to compensate reactive components and to provide power adjustment, so the antenna radiates supplied TX power Peff via the radiation resistance R.
Deviating from the antenna registered as standard for a respective band (see 5.2.3 Antennas), also an another antenna can be choosen by touching switching area Actually Choosen Antenna. 6.3 Manual tuning To manually detect and save a tuner configuration and settings for a given antenna / frequency combination, proceed as follows: ► Adjust input power between minimal 4 W and maximal 39 W.
6.4 Automatic tuning For automatic detection and to save a tuner configuration and settings for a given antenna / frequency combination, proceed as follows: ► Tap at switching area Tuner Mode until the the switching area appears red and “MAN“ will be displayed. ► If the antenna tuner is bypassed, tap at switching area Bypass until “L“ and “C“ are displayed. ► Adjust input power between minimal 4 W and maximal 39 W. ► Tap at switching area Tune.
6.5 Indication area Segment-Size (At present, memory segmentation and querying the neighboring segments is not yet possible. The function will be activated in one of the next versions as part of an update). Indication area Segment-Size displays the usable segment width for a stored setting in kHz. The term Segment-Size describes the frequency range for which a stored setting can be used. - The lower the transmit frequency, the narrower this frequency range becomes.
6.6 Bypass the antenna tuner For testing purposes, or when using resonant antennas or an external antenna tuner, the internal antenna tuner may be taken out of the transmit path.: ► Tapping again the switching area Bypass, inserts the antenna tuner again into the transmit path. ► Mode “MAN“: Tap at switching area Bypass to bypass the antenna tuner. Mode “AUTO“ Mode “MAN“ ► Mode “AUTO“: Tap at switching area Bypass, to bypass the antenna tuner.
