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.
