Configuration

Operating manual HVC 32 a. HVC 42 -

First configure the amplifier for the transmission of forward signals:

ASK

Remove the housing cover by loosening the cover

screw.

When the devices are delivered, the HVB 32, HVB 31 and HVB

42 amplifiers have an attenuator (0...15 dB) [1] and a tilt equal-

iser (0...15 dB) [2] (see left) in the input, which are screwed in.

They can be used to set the desired attenuation and equalisa-

tion. (Input and output are protected against overvoltage.)

You can set an attenuation (0 or 6 dB) between the amplifier

stages by reinserting the jumper [3] accordingly. Observe the

labelling.

You can also set a pre-equalisation of 0 or 7 dB between the

amplifier stages by inserting the

jumper [4] accordingly.

ATTENTION

be exceeded! (maximum input level = output level minus the

set gain for 1006 MHz)

ESULT

The device is now configured for the transmission of forward sig-

nals.

To transmit return signals, the amplifier must be configured accord-

ingly.

The following describes how to configure the amplifier for the trans-

mission of return signals:

ASK

When the device is delivered, the attenuator (0...15 dB) [5] is

screwed in and must be set according to the cable network

specifications.

When the device is delivered, the tilt equaliser in the return

path [6] is screwed in (see picture left) and must be set

according to the required cable pre-equalisation or post-equal-

isation.

ESULT

The device is now configured for the transmission of return signals.
