Continuous operation
- Convection cooling- Generously dimensioned heat sink
- Gradual power degradation in case of adverse operating conditions
- Automatic switching off at critical temperature
- Continuous output via control of external Blower Unit R&S IZ200, e.g. for ATIS or VOLMET service
| High communication link reliability |
| Rear heat sink | Cost-effective installation in standard racks
- L-shape plug-in slide rails are sufficient
- No need for telescopic rails
|
Variety of PTT (push-to-talk) techniques
- Via front-panel switch: unmodulated (PTT) or modulated (TONE)
- Via microphone key
- Via a wide control voltage range: floating via optocoupler or negative pole to ground (via optocoupler or phantom circuit)
- Via serial interface (REM BUS)
| High system flexibility
- Interface adaptable without problems
- Easy to test
|
Excellent spectral purity
- Low-noise synthesizer
- Careful design of power amplifier etc (minimizing non-linearity product emission)
- Harmonics filter
- Special models with additional VHF or UHF Lowpass Filter R&S GH200V/U to comply with German Telekom Guidelines for spurious emissions on request (if used without external filters)
- VHF or UHF Circulator Set R&S GD200V/U (option) provided for insertion in front of harmonics filter (maximum efficiency) to improve TX intermodulation characteristics
| Interference-free operation
even under co-site conditions |
Future-proof and cost-effective transmitters
for multiple applications "all-in-one" Standard transmitter models
- For standard operation or
- For 2-, 3-, 4-carrier offset operation (with 25 kHz spacing)
- For future 8.33 kHz mode: no need for expensive change of synthesizer; for final 8.33 kHz upgrading the optional Modulator Extender
- R&S GM201C8 has merely to be inserted into the customized option slot of the transmitter
- For single- and multichannel operation, thus reduced logistics effort
High-precision transmitter models for special applications | Same benefits as before
(except 8.33 kHz) |
Designed as 19" 3 HU plug-in unit
- Internally and externally loaded modules
- Slots prepared for present or future options
- Space for future customer-specific options
- No motherboard
- Swivel-type design of rear power amplifier module for ideal accessibility in the event of tests during full operation; heat sink and flexible cabling remain connected
| Helpful service functions for fast status checks |
| Clearly arranged control and monitoring elements on front panel |
