Some options cannot be retrofitted. If the genlock option for test signal insertion is fitted, switchover to the selected substitution pattern is ensured in the case of program failure. Whether analog or digital terrestrial TV, cable, satellite and mobile TV, or sound broadcasting — all these signals can be modulated in realtime. Irrespective of the realtime coders used, it is possible to generate user-defined modulation signals by means of an optional arbitrary waveform generator and to replay waveform files of the customer.
Average power specification: at MHz approx. The order numbers are for reference only. The actual order numbers of the system depend on the configuration. LDMOS transistor-based amplifiers ensure high output power while requiring only minimum space. The available output power ranges from W to 1.
This means that the transmitter control unit and the bus system for internal and external communications are identical throughout. The transmitters include the components exciter, power ampliier s , transmitter control unit and transmitter rack with cooling system. The transmitters are innovative, robust, failsafe and easy to put into operation. This makes them ideal for use at remote sites and in outdoor applications.
The transmitters can be switched from analog to digital transmission. Rolling out or expanding a transmitter network may require large numbers of transmitters; yet costs must be kept to a minimum.
The new backup exciter redundancy concept eliminates the need for a separate transmitter control. This lowers costs and increases system availability. Each amplifier comes with two power supplies.
This ensures high failsafety, which can be further enhanced by adding a third, optional power supply. Important: To comply with the applicable standards and limit values for the suppression of out-of-band emissions and in the case of digital standards, also for maintaining the required shoulder distance , the transmitter may only be operated with suitable filters at the RF output.
Only two modules, exciter and amplifier, are required in this case. All operation-relevant interfaces are fully integrated into the units. Additional components to be built into a rack are required only for standby systems or if several amplifiers are combined to boost output power. Thus, an enormous number of transmitters or re-transmitters will be required in the very near future, especially for low-power applications. Despite the high quantities that will be needed, budgets should not be overstrained.
Space in low-power transmitter sites is often very tight and the voltage supply is often not ideal. Moreover, the transmitters are sometimes difficult to access. Thus, high requirements are placed on transmitter ruggedness, flexibility, compactness and easy transport. In this case, a common standby transmitter is available for one to eight main transmitters. The standby transmitter stores all data required for the active transmitter systems and can replace the affected transmitter in the event of a failure.
The entire system, including all associated distribution and switching units in the signal paths, is monitored and controlled by an independent, higher-level switchover unit. They are reliable, compact and flexible. Plus, they are specially designed to meet the requirements of small, remote transmitter sites that are difficult to access, offer only limited space and whose power supply may be subject to strong variations.
The ultracompact devices can be used as transposers or retransmitters. Feedback is eliminated by high-quality, two-level echo cancellation. The compact but flexible all-in-one-box concept allows various options to be integrated, which simplifies logistics and handling when sites are difficult to access. If necessary, a transposer can be easily converted from analog to digital TV without modifying the hardware.
High availability means reliable broadcasting operation for the customer. The transmitters can be flexibly adapted to special requirements in the transmitter stations and they feature a convenient operating concept. By providing excellent signal quality with a modulation error rate MER of typ.
Large shoulder distance and low out-of-band emissions are the crowning touches to the impressive characteristics of the RF output spectrum. The space-saving design increases the lifetime of the transmitters by making efficient use of materials and providing short signal paths.
Each transmitter station has its own requirements for cooling, RF connectors, or remote control. As a beacon to the future, the transmitter family is prepared to handle the implementations of expansions to existing or new standards. They can continue to use the existing infrastructure as the multiplexer can be easily integrated into the current system. The advantages are obvious: Broadcasters can enlarge coverage without changing their transmission licenses and reach a greater number of viewers.
Seamless handover between transmitters is ensured. In an SFN, all parts of the transmission chain need a highly precise time signal for synchronization. The multiplexer receives the time reference from an NTP server. This is a cost-effective and easy approach. Due to the intuitive web interface, the user administers data in a single location and not on several devices and thus saves time. Furthermore, all commands for automatic monitoring and for settings are available via an SNMP interface. This allows broadcasters to change to this future-oriented Internet infrastructure at any time.
But experience has shown that good support is what makes a good product a good solution. Your desire — our commitment Full-range service at your command There is one goal common to all service operations, no matter how different they may be in detail: to protect your investment and maximize the added value.
As with all precision technology, these products require expert maintenance so that their specified performance, for which you as the customer have paid, is available to you in the long term and can be used in your application. For example, they can install the latest firmware version or hardware options. If a useful hardware modification has been made to the product in the meantime as part of a model update, this innovation will also be incorporated, usually at no extra cost to you.
After submitting your unit for calibration, it will first be given a thorough check so that inconsistencies of any kind can be detected and the necessary steps taken. This ensures that your equipment will be returned to you in top shape and that you will be able to profit from its peak performance for years to come.
Maximum automation Our smart calibration systems ensure maximum reliability and efficiency A quality calibration must be precisely defined and repeatable and it must be possible to document it down to the last detail. In addition, it must be efficient and standardized in order to keep turnaround times short and handling costs low. See you at your premises The alternative: on-site calibration Measuring instruments and systems in production facilities are very often in operation round the clock and are thus highly indispensable, even for short periods.
But, at the same time, inaccurate measuring equipment frequently has a negative effect on production yield, so the recommended calibration intervals should be adhered to as much as possible. The solution to the dilemma: on-site calibration. Just speak with your service advisor if this type of calibration service is of interest to you.
Traceability guaranteed ISO certified? We back your obligations Your product will be returned to you with a calibration label, a calibration certificate and a detailed test report in line with ISO You thus fulfill all the requirements of ISO with respect to the complete traceability of your measuring equipment to internationally recognized standards.
For several of our service centers are also nationally accredited calibration centers. And even if not, they will still be able to help you. International agreements between accreditation authorities allow in many cases recognition of calibration in line with German Calibration Service DKD standards and we can offer you this anywhere. These systems make our comprehensive calibration know-how standardized and available worldwide.
Equipped with calibration routines for all the important equipment series, they form the backbone of our calibration network. The advantages for you are obvious: short handling times, low costs, high testing depth and reliability and international comparability of results.
