Frequently Asked Questions - 17ZR TECHNISAT

What is the TechniSat 17ZR used for?

The 17ZR is an intermediate amplifier designed to compensate for signal loss (up to 13 dB at 2150 MHz) caused by cables and components in large satellite and terrestrial distribution systems.

What is the frequency range of the 17ZR?

The 17ZR operates in the terrestrial range from 47 – 862 MHz and satellite range from 0.95 – 2.15 GHz.

How is the gain adjusted on the 17ZR?

The terrestrial gain is adjustable via a control screw. The satellite gain is fixed but can be influenced by the slope correction. Refer to the manual for detailed adjustment procedures.

What is the power supply requirement for the 17ZR?

The 17ZR is powered via the trunk lines with DC voltage (13V or 18V). It consumes 180 mA at 18V and 120 mA at 13V.

Can the 17ZR be cascaded with other units?

Yes, the 17ZR can be cascaded with active branch distributors (17/2AR) and other amplifiers. It is designed for installations with up to 1000 participants.

What are the dimensions and weight of the 17ZR?

The 17ZR measures 212 x 58 x 45 mm (L x W x H) and weighs 0.7 kg.

What safety precautions should be taken during installation?

Install the device in dry, non-flammable areas. Do not cover ventilation slots. Ensure the antenna system is grounded and protected against lightning. Always disconnect from power before installation. Only qualified personnel should open the unit.

What is the recommended input level for the 17ZR?

The recommended input level for terrestrial signals is 58 dBμV, with a maximum of 70 dBμV. For satellite, the recommended level is 55 dBμV.

How do I clean and maintain the 17ZR?

Clean the unit with a dry, soft cloth. Do not use liquids or solvents. No internal maintenance is required; if a malfunction occurs, consult a specialist.

Where can I find spare parts or repair information?

Spare parts and repair services are available through TechniSat customer service. Visit www.technisat.de or contact your local distributor. The unit is not user-serviceable.

1 Application

With these devices you can implement installations for up to 1000 participants, all are fed from the same external unit. Fundamental explanations can be found in the installation instructions for the GigaSystem 17/8G and K.

In all these accessories units the return channel signals are transmitted to the CMTS (Cable Modem Termination System) in a linear frequency, passive, low-dam-ping mode. In the process, the terrestrial system is operated as an active one.

In conjunction with suitable headend- and participant- technology, this enables the provision of fast Internet access, VoIP, and voting options – all without the need for additional cables to be installed.

Such applications are only cost-effective in large installations.

2 Safety instructions

For your own protection, please read the safety notes carefully before installation.

The manufacturer assumes no responsibility for accidents resulting from or associated with inappropriate handling of system or by non-compliance with the safety precautions.

The components must be installed in dry rooms on level surfaces that are non-flammable.
Do not cover the ventilations slots of the components.
Do not install the units in roof insulation material.
Install the equipment while it is not connected to the power line.
Ensure that the antenna installation is grounded.
The antenna equipment must be protected against lightning in accordance with local regulations.
All relevant European standards and VDE regulations concerning electrical safety must be complied with.
National regulations regarding the licensing of wireless reception equipment must be considered.
Do not under any circumstances open the housing of the product.

If it becomes necessary to open a unit, only trained specialist personnel should perform this. Disconnect unit from the power supply and call a specialist in the following cases:

The unit was exposed to high levels of humidity, or liquid has run into the unit,
In case of malfunctions,
In case of significant external damage.

3 Intermediate amplifier 17ZR (Art. No. 0000/3269)

The amplification levels as well as the fixed slope rectification of this unit are specifically designed to compensate the damping caused by cables and/or components of maximum 13dB at 2150MHz.

The unit should be used when the level has already dropped a little.

It combines all horizontal and vertical trunk lines with each other by means of direct current (except SAT1, High Band), so that the DC-resistance of individual trunk lines is decreased. The amplification of the terrestrial path is adjustable.

4 Active branch distributor 17/2AR (Art.-No. 0000 / 3270)

The active branch distributor 17/2AR is a component of the GigaSystem 17/X.

It serves to provide low-loss branching of signals from trunk lines.

It can be cascaded up to 6 times to provide signals for the sub-distribution nodes on the different floors of a multi-storey building, or to neighbouring houses in a row of houses.

Use multi-media cable for the trunk lines. The amplification provided by the units is suitable for practical applications, and provides narrow tolerances. The trunks consist of (passive) directional couplers with very low attenuation. This fact, as well as outstanding isolation, ensures that up to 6 units 17/2AR can be cascaded To compensate for the attenuation resulting from the cable used, please use one or more intermediate amplifiers 17ZR.

The device itself is fed with DC voltage from both sub-trunks 1 (the taps), but it does not feed the (main)-trunks. To feed matrices, amplifiers and LNB's in the (main)-trunk, you must connect a 17/8G unit to the trunk output of the last 17/2AR.

If the terrestrial amplification is to be reduced in a linear manner, use the attenuation adjustment control. Additionally a slope adjustment is implemented.

To ensure reliable function with reserve capacity in larger installations, it is essential to calculate levels, isolation, voltage drops and the power loads of supplies before proceeding with the installation.

An example of this is shown in chapter 6.1. The data can be found in the technical specifications and chapter 8 below.

This device has a maximum loss of 4dB and distributes the signals of the 16 satellite IF planes and of the terrestrial path to two outputs. The upper output provides direct current decoupling in order to prevent any mutual interference by the power supplies feeding in current.

1) Isolation of the 17/8K, for calculation purposes without consideration of the LNB's
Together with the 25dB of the LNB's at best there will be arising approx. 24dB isolation. If you add two 17/2AR and one 17ZR in a longer installation (see 6.2), the isolation decrease to worst ca30dB (
=> That's just enough to operate.
