I am obsessed with getting the TV distribution system performing well through my house.
The system includes analog cable, 3 channel modulator and 13 TVs.
I am breaking down the problem into the following pieces
1) Verify Cable signal alone is good
2) Verify Modulator signal alone is good
3) Combine cable signal and modulator and make sure it is
4) Distribute the signal through the house.
I need instruments and what I am looking for to complete this.
1) What instrument do I buy to measure cable signal? and Modulator signal?
2) What should the signal measure on the instrument?
