How to DIY 同軸數碼線

Any location details of collect cable and How to connection of parts?

Assume un-balance cable and normal coaxial wire.

1. Understanding the characteristic impedance

2. Understanding the impedance of your gear, some machine is 50ohm, some machine is 75ohm

3. Identify the connector type, BNC, RCA

4. Get a cable spec from the supplier

5. Cutting the cable according to the best "wave length"

6. Use recommened cable tools to assemble the cable and the plug. (not soldering)

7. Testing the "impedance"

KK.thanks for yr information.

KK sir,

long time no see. How are you? Looks like you put on weight. Must be happy happy.

Can you elaborate Point 5. Cutting the cable according to the best "wave length" and Point 7. Testing the "impedance"? How to do them?

What is your comment on using Cat5 cable for digital RCA connection?

"Wavelength for dedicated length "
--> which show in the datasheet of your cable.

Simpe method to testing the impedance, please join our cable course later.

Characteristic impedance and VSWR

Assemble instruction from Canare Cable.

Need dedicated tools!!!

kk sir,
Thank you very much. I'm learn more from yr.
But it look very difficultly to DIY.

MSIU,

Do you want we open a class about this ?

Please advise what kind of cable you are interest.

For 75ohm impedance cable, it is more important for "matching impedance"

1. Coaxial cable for Digital transmission (Analog)
2. Components (YUV)
3. VGA (RGB, HV)
4. Antenna Cable

Please comment

I want DIY a Coaxial cable for Digital transmission.
Any suggestion of plus can choose .
