While usin the ONX-630, Always use Ingress Expert, and NEVER use Average power. You will never see the accurate amount of noise on the line. Max Power and Max hold.

Love the DSam is the best meter to track noise

To everyone that"s been hating on the ONX 620/30 ingress expert mode... 1. I would bet money that if trained properly on the ONX, you'd never pick up a dsam or 1G again (well. The 1G is pretty tight too). 2. How many of you ran docsis expert first in order for the ingress expert app to lock the upstream channel descriptors?

Si conectara el medidor al puerto 2 del equipo alli si mediria retorno porque alcanzo a ver que lo tiene conectado al puerto 1 que es el de bajada ( si estoy equivocado perdon 😂😂😂😂)

Amtrak train?

I have also noted (recently) that the ONX-620 will often default to a noise floor of -60dBmV and doesn't adjust to where you would normally expect the noise floor to be (-40 dBmV). Often times, with a lot of noise you are greeted with a constant "excessive ingress" display and the only to get this to go away is by turning the AGC on. When you turn the AGC on, you can see the noise floor move then as it adjusts (adds attenuation). Sometimes this moves the noise floor down to levels lower than -30 dBmV. This has obvious flaws considering a 25db spike from a -60 dBmV noise floor will only be measured to -35 dBmV which means it's in a "passing" range whereas if the noise floor were accurate from the jump (around -40 dBmV) your spike would be badly failing at -15 dBmV. Not sure why this is happening. In any regard, clearing a house of ingress is so much easier with the DSAM than with the ONX. If anyone knows WHY the ONX 620/630 is defaulting to show the noise floor at -60 dBmV, I would love to hear it. (my suspicion is that the meter is being effected by the downstream channels and may require use of a low pass filter). Still....operationally I would much rather be chasing house ingress with a DSAM than an ONX at this point.

Cable TV - Total Garbage! Way past its prime! Bring on the Fiber!

Nesecitas un filtro que te muestre solo el retorno, por que ese medidor no tiene el diplexor que te separa el retorno del forward, hay uno de la marca pct PCT-BSFA-96-517 Con ese filtro solucionas tu problema, buena suerte 👍🏻👍🏻

When was the last time that meter was calibrated? Also, the OneExpert might be zoomed out and therefore showing fewer details. Try adjusting your Vertical setting before you rotate the screen.

Why no recent videos please?

change db/div maybe to see the noise better?

I think that's why I don't use that meter for casing noise and stay to the DSAM.

Good reminder, Thanks!

That was an Awesome example bro. Appreciate you doing the video. I'm a tech 3 in Palmdale Ca. Keep up the good work.

0:47 in this backyard easement...NODE... :)

The Viavi blows away the DSAM once you learn it. Turn on heatmap.

Serious question, new MT here. Can you post a pic of that probe, I’ve asked to see one me nothing.

What are you doing taking down plant like that

Love the DSam spectrum. Glad to see you using a meter to track noise .

Great troubleshooting.

im using VeeX for that same thing not much details Dsam is the best , whats the name of the app in your phone ?

the only solution is to send a technician to inspect to customer installation

Good job

Plus you already saw it leave when you floated the output screw. I go to your last tap and start taking drops off.

Why are you even bothering with the 2nd meter? Use D-Sam and path-Trak

I learned if you turn your AGC off you don't have to keep pressing reset.

You could have saved all of those steps by looking at pathtrak, dropping the tap plate then hitting the button inside the tap and then watch the noise drop on PT.

Hello I've been a field tech installer for comcast for 7 years now. How did you get your job in network maintenance? Should I be studying for some certifications in order to stand out for the promotion?

I've seen people plug their rg6 outlet to a surge protector.

This is awesome! Very well explained. Thank you for sharing the knowledge!

Surprising how many loose fittings I find all over trouble calls, daily. Some guys don’t bother carrying a wrench I guess.

god bless

How did you resolve it - by unplugging the backfeeding customer?

Why is MER so important?

how do you see the noise on your phone?

dont know what kind of noise that was, but all that was is a machine, ie the modem, struggling to connect because it had to jump an air gap. it was not ingress but the modem screaming. soon as you tightened the fitting it started talking normal on the network....period

Sir ji can you please help me

How would/did you resolve the issue without full disconnecting the customer? Did you use a negative trap?

What kind of stupid fucked up ass-backwards system do you work in where they don't want shrink on the connectors but they want bishop tape on the housing to housings? Fuck them.

Thanks for showing us what can cause what. :)

Damn MER @ 42db at the tap.. not bad

what spectrum analyser are you using and how do i remote into the viavi one expert

Good job you know your s!$t

When you are in ingress expert (which is what I prefer to use, not ingress scam), press the up arrow hard-key twice and it will zoom your trace in. Unfortunately because of the dynamic range of the meters analyzer, you must use auto AGC when you’re probing with the ONX. You have to be cognizant that if auto AGC is turned on, you have to hit reset whenever you plug in to something new or cause your noise floor to raise (eg: by loosening or tightening a seizure screw). This doesn’t happen when Auto AGC is turned off. You can turn the auto AGC off when you are using yours amps test points though (because they are 20dB, 25dB down etc). With that said, you may be able to get away with using a 20dB probe (such as an iStop) with Auto AGC off to have a better experience chasing ingress. Again, just make sure to zoom the trace in a bit because it will be harder to see the noise: A) because you’re used to the DSAM and B) because the noise will be attenuated by the probes attenuation value

Love this video!! I hate using ONX to track. there have been no training on using ingress expert. The videos you watch from the company are garbage. I want to physically see someone plugging the leads into an active etc...like what you've done with the taps. We are all just play with it...I no longer have a dsam...😞.

What app is that on your phone?

Haven’t ran into this problem yet, good too bro!

ILOVE cable TV job

I just love cable TV work, can you help me
