What is forward path attenuator 10db?

The 3dB forward path attenuator will decrease the whole signal by 3dB. The 4dB Simulator decreases the low end by 4db in a slope (opposite the equaliser) Sometimes it is what is required to get the signal perfect.

What is a forward path attenuator used for?

PPC’s forward path attenuators provide a fixed level of attenuation within the downstream frequencies without affecting upstream frequencies. Typical applications include attenuation of over amplified signals generated by drop amplifiers at the first input.

How does a forward path attenuator work?

Forward path attenuator – weakens (attenuates) the high frequencies used for downstream only, without affecting the upstream frequencies. When you attenuate the upstream frequencies, the cable modem is forced by the CMTS to increase its power, to “speak louder”.

What is a coax attenuator?

A coaxial attenuator is an electronic device specifically designed to reduce the power of a signal without affecting or reducing the waveform of the signal significantly. Amplifiers provide an increase (or gain) in the power output whereas an attenuator provides a loss of power (or a gain less than 1).

What should my upstream and downstream power levels be?

Downstream and upstream power levels are important when determining if the cable line that is connected to your cable modem or modem router is receiving sufficient power. Good Downstream power levels are within -7 to +7 dBmV. Good Upstream power levels are within 38-48 dBmV.

Where attenuators are mainly used?

Applications: Attenuators are generally used in radio, communication and transmission line applications to weaken a stronger signal. Resistive attenuators are used as volume controls in broadcasting stations and also can be used for matching circuits of different resistive impedances.

What is a good downstream SNR?

The modem status will show the downstream SNr (signal to noise ratio) which usually should be above 30, mid to upper 30’s is good, over 30 usually means you’ve got too much power anyhow, and under the 25-30 range you’re gonna start losing packets.

What does a forward path attenuator do?

Forward path attenuator – weakens (attenuates) the high frequencies used for downstream only, without affecting the upstream frequencies. Return path attenuator – weakens (attenuates) only the low frequencies used for upstream.

Which is PPC forward path attenuator 6dB 75?

How does a 10 dB attenuator pad work?

Put this on the back of the cable modem and the downstream voltage went down quite a bit (still in spec), and the upstream voltage went up – putting it into spec. If you’re wondering if this will work for you, a splitter will do the same thing. Normally a splitter will have one input and 2+ outputs. Each output labeled with -7db (or some number).

Why are there two 6dB attenuators from the cable going?

Because your signal is too hot. Too high on the channels used for your cable modem. More does not equal better, signal to noise ratio does. Much better to attentuate a high level than amplify a low one. It has nothing to do with your house and the BS your builder gave you.
