Network setup and activation (Ulearn Network Technician Core Skills)

Question 1

SLM

Answer 1

Signal Level Meter

Question 2

Used for the first amplification stage for a trunk or multi-output station is picked primarily for a low noise figure, as input levels can vary between 8 and 15 dBmV

Answer 2

Integrated Circuit (IC)

Question 3

Electronically adjusts its attenuation to hold the pilot carrier output level constant with changes in its station’s input level at that frequency

Answer 3

ALS and/or AGC

Question 4

This device monitors the temperature change and makes an attenuation and tilt change based on typical cable spacing between stations

Answer 4

Thermal level control unit

Question 5

Prepares the signal for the next round of insertion losses to attain the station’s operational gain. This is usually a power-double device.

Answer 5

Second Stage Gain

Question 6

With a value other than 0, is used when the station’s input level has been properly set and its output level exceeds the system’s design specification.

Answer 6

Interstage Pad

Question 7

Compensates for the frequency response “signatures” of passive and active devices in the system. Some are plug-ins, some are hard-wired, and some are not easily accessible, especially those that affect “match” (return loss).

Answer 7

Response Network/Mop-up

Question 8

Sets the amplifier’s output tilt. For some manufacturers this is hardwired in the station.

Answer 8

Interstage Equalizer

Question 9

Accepts an optical carrier transmitted from the headend or hub over a fiber optic cable. An optical detector demodulates the RF carriers from the optical carrier, amplifies, and makes available to as many as four output ports.

Answer 9
