Thanks. How do we know how much power to use for the signal generator? Does the TX power change the cable loss amount?

Hi, The power level to use for a signal generator and its impact on cable loss depends on the specific application and the characteristics of the signal path.
Yes, Tx power will reduce by the cable if the cable have high loss amount (high attenuation).
For detail explanation:
The power level of the signal generator can be affected by cable losses. As signals travel through cables, they can experience attenuation due to the cable's characteristics. The amount of cable loss will depend on factors like the cable's length, frequency, and the type of cable used. You should account for cable losses and set the signal generator's power level accordingly. If you know the cable's loss characteristics, you can compensate for it by increasing the generator's output power.
