# Analog Set Period
Configures the period of the Pulse Width Modulation (PWM) on the specified analog [pin](/device/pins) (``P0``, ``P1`` or ``P2``). Prior to calling this function, the given pin should be set as analog.
```sig
pins.analogSetPeriod(AnalogPin.P0, 20000)
```
### Parameters
* `name` - [String](/reference/types/string); the pin name ("P0", "P1", or "P2")
* `micros` - a [Number](/reference/types/number) representing the micro-seconds of the analog period.
The following code
```blocks
pins.analogWritePin(AnalogPin.P0, 512)
pins.analogSetPeriod(AnalogPin.P0, 20000)
```
