AVA Series (10 kHz – 30 MHz)
Up to 4 Inputs and 10 Outputs – According to Customer Needs
No Restriction of Antenna Selection
Description
The AVA 10 is available in various configurations with 1 – 4 inputs and up to 10 outputs. It covers the frequency range from 10 kHz to 30 MHz.
The units are designed for integration into 19-inch racks. They require only 2 HU so its small footprint allows for flexible integration into the application environment.
The AVA features
- No restriction of antenna selection
- Number of inputs and outputs configurable
- Fast input to output switching
- Switchable input protection (auto – 0 dB – 6 dB – 20 dB)
- Special preamplifiers available for limitation of frequency range or passive bypass
- Watchdog for active antennas, preamplifiers and channel amplifiers
An integrated control unit controls the antenna distributor AVA. Local control from the front panel, remote operation through RS232/RS422 interface or Ethernet LAN interface 10/100M is supported.
Customer specific requirements can be considered.

Options
The AVA 10 can be configured with these options according to customer needs:
- output sockets typ N instead of BNC
- addional power supply 18-36 Vdc (ground free)
- with automatic switch-over in case of mains failure
- Remote control Ethernet LAN 10/100 interface instead of RS 232 / RS 422 interface
- Front panel with special varnish according to customer specification
Type Designation (Configuration)
The type designation of the AVA 10 is AVA 10 X1 – X2 – X3 – X4 – X5
| X1 |
Option BNC = BNC sockets |
| X2 |
Configuration L = 0,01 – 30 MHz (standard) |
| X3 |
Configuration H = 0,01 – 30 MHz (standard) |
| X4 |
Option DC = power supply unit with additional input for emergency operation |
| X5 |
Option LAN = Unit is equipped with Ethernet LAN 10/100 interface instead of |
The following examples shall help to find the correct type designation.
Assuming an AVA 10 with 3 inputs, 6 BNC outputs, supply voltage 230 Vac and RS232
interface shall be the need, the type designation is
AVA 10 B – 3L – 6H
Assuming an AVA 10 with 4 inputs, 10 N outputs, supply voltage 230 Vac and 18-36 Vdc, remote control through the LAN interface and input 1 shall have a passive bypass, the type designation is
AVA 10 N – 1L1 – 3L – 10H – DC – LAN
