THE 5 STEPS TO DSIMP
11
Step 1

Ask the customer to turn on all appliances
including TV,VCR,DVD -the more equipment they
turn on, the better.

12
Step 2

Plug the customers drop into your meter and check
the 5 to 42 mHz return Upstream Spectrum - 30
dBmV is our benchmark We are looking for
ingress energy to be lower than - 30 dBmV.

13
Step 3
Forward and
return scans must be made. Tiling can be caused
by unwanted energy under forward carriers also.

Step 3

• Peak Hold-
