1 Safety and warning notes

This equipment must be installed and operated by qualiﬁed and trained

personnel only.

Please familiarize with the instructions before start-up.

Carefully inspect the device for any obvious damage. If it appears to have been dama-

ged, contact your WISI representative.

Do not use any equipment with noticeable damage!

1.1 ESD protection

This product contains electrostatic sensitive components.

These parts can be damaged or effectively destroyed by electrostatic di-

scharge (ESD) during unpacking, installation, removal, storage, or shipment

if incorrectly handled.

Please note that discharge might go unnoticed by a user.

Always take common antistatic precautions when handling the equipment.

1.2 Electrical safety

Risk of bodily injury from electric shock!

Failure to adhere to these instructions could result in personal injury and/or

damage to electrical components.

• The equipment must be grounded in accordance to local and national electrical

standards.

• The device is started up immediately when the power plug is inserted into the

mains socket. To turn off the power supply, the plug must be removed from the

socket. Never pull at the cable.

• The mains socket should be easily accessible. In the event of operational error, the

plug must be immediately removed from the socket.

• The power supply partition of the equipment as well as all coaxial interfaces carry-

ing remote power feeding contain dangerous voltages. All service or maintenance

work should be carried out by qualiﬁed personnel who can get assistance by con-

tacting the manufacturer’s agent.

VX 56 B / VX 57 B series

RF ampliﬁer - dual output stage

The optional spectral monitoring module WISI VX 58 B provides a spectrally resolved

level measurement. VX 56 B / VX 57 B leverages this for three main functionalities:

1. Spectral monitoring of the output downstream signal (section 4.3),

2. Auto-alignment of downstream and upstream signal paths (section 4.4), and

3. Automatic level and slope control (ALSC) / pilot regulation (section 4.5).

NOTE on the reference point for the measurements:

The measurement signal is tapped from the output ampliﬁer stage of RF channel 2

(see diagram in section 4.1).

All levels are monitored for RF output 2, so keep in mind that RF output 1 can deviate

if an asymetric output conﬁguration module (see section 4.1.1) is plugged or if the

output 1 attenuator (see section 4.1.4) differs from 0 dB.

3.2 Bluetooth interface basics

The management interface of the ampliﬁer can be accessed using the bluetooth low-

energy (BLE) wireless technology. The bluetooth antenna enables the radio connection

to a smart phone or tablet.

The Android app WISI HFC Manager+ provides the GUI for the conﬁguration of the

ﬁber node, whereas the WISI HFC updater brings ﬁrmware update and recovery func-

tions.

access. The ﬁgure below shows the security levels and the according security mecha-

nism.
