The compact amplifiers with electronic tuning elements –

VGP 9033-1G/9041 and VGF 9030/9040

With the VGP 9033-1G/9041 and VGF 9030/9040 Kathrein offers a latest-generation compact amplifier series. A wide range of settings, electronic operation and excellent technical data – at an unbeatable price/performance ratio.

"Plug-and-Play" redefined

Electronic setting of all important parameters, automatic levelling (only for VGP 9033-1G/9041) as well as remote configuration via HMS or DOCSIS monitoring ensure the shortest start-up and maintenance times. The copy function enables one to copy all settings and transfer them to another device at the press of a button.

The absence of plug-in cards for gain and slope not only accelerates start-up, but also simplifies logistics and saves warehousing costs.

Another advantage during modifications:

new values are taken over without any interruptions. Multimedia services remain undisturbed.

Start-up without a measuring instrument

– it doesn't get any easier than this

Due to automatic levelling, the compact amplifiers VGP 9033/9041 can be put into operation

with just a few steps:

-Simply enter the desired output level for the lower and upper pilot frequency and start levelling

-After a few seconds, the device automatically sets the desired values, whereby optimal technical data are continuously reached.

Manual vernier adjustment is still possible at any time.

-Subsequently, automatic presetting can also be effected in the return path.

-For the next devices, levelling runs even more quickly. The copy function enables desired settings to be automatically incorporated.

The compact amplifier with slide switches –

VGO 939-1G/VGF 939-1G

In addition to the devices with electronic setting, Kathrein offers yet another highly innovative compact amplifier platform. This particularly economical series requires no equaliser cards

or attenuation pads. All adjustments can be easily carried out using slide switches.

Simple, yet effective

The required attenuation and slope values are set with a combination of several slide switches. The advantages are obvious. Besides saving plug-in cards, this allows exact reproduction of setting values without requiring a measuring instrument.

Replacement of the device, for example, is thus much easier.

When slide switches are shifted, a virtually uninterrupted signal flow is guaranteed – multimedia services remain undisturbed.

Maximum reliability

The implemented slide switches fulfil the highest demands regarding reliability and endurance. Dual gold-plated contact reeds, increased contact pressure and a separate catch spring ensure ultimate reliability of the switches, which have been proven and tested 100,000 times.
