**How to convert Optical RX Value to dBm Few Value are Ok But Few Value not ok**

**I Need Some For Convert To dBm Value**

The easiest way to accomplish this is is a virtual param. This will give you the most flexibility.

Another way of accomplishing your goal is Admin → Config → Edit index page, then find your Pwr param and append ` || ' dBm'`

so you end up with something like this:

```
- label: "'Pwr'"
parameter: Device.Some.Node.PowerOrSomeOtherParamName || ' dBm'
```

thanks for the same but this is not right — {Math.ceil(10*Math.log10(Value/10000))} for raw value to dbm convert

Then use a vparam to do the calculations

please give me some examples

console.log(Math.ceil(30 + (Math.log10((value rx power * (Math.pow(10,-7))))*10)));

i have this logic, how to add in my virtual parameter?

value rx power =

- InternetGatewayDevice.WANDevice.*.X_ZTE-COM_WANPONInterfaceConfig.RXPower
- InternetGatewayDevice.WANDevice.*.X_CT-COM_GponInterfaceConfig.RXPower
