> General Measurement Setup

> Warning | Maximum power level to the Site Master S331L Power Meter connector without causing damage is 27 dBm.

> Connection and Offset

> 1. | Connect the source to be measured to the power meter connector. Use any required external attenuation or gain so the expected power level is between -33 dBm and +20 dBm.

> 2. | Press Amplitude then Offset Value. Enter an offset value for any external attenuation (negative value) or external gain (positive value). The displayed power will be adjusted by the offset value.

> As an example, a power source around 1 Watt (30 dBm) would cause damage to the Site Master and is beyond the measurement range. 10 dB of in-line external attenuation will bring the power level down to approximately 100 mW, within the power meter measurement range. In power meter mode, adding a Offset Value of -10 dB will remove the external attenuation from the displayed power level.
