Need help for ADS equation reprentation...

I want to convert the output plot from dBm to mV

But I don't know how to express exponential equation in ADS as Eqn
I'd checked it out from ADS help, but only find the exp() ...

P[dBm] = 10*lg (Po[mW]/1mW]), & consider Lload=50-Ohm

For example: how can we express a^b in ADS Equation ?

Please, help me

Thanks !

This table shows the relationship between Power in [dBm] or [Watts] and Voltage in RMS, peak, peak-to-peak for sinusoidal signals in 50-Ohm systems. **broken link removed**

Hi,

My hint:

dBm refers to 1mW.

Now you want to refer it to the voltage on a 50 Ohms resistor.

This leads to the question: How much voltage on a 50 Ohms resistor do you need to cause 1mW?

In ADS help, search for function dbmtov()

That is function pow()

You can find a list of functions here:

You're so sweet, Thank you @volker. I got it.
