> Connection and Offset

> 1. | Connect the source to be measured to the USB sensor. Use any required external attenuation or gain so the expected power level is within specification for the sensor.

> 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) may cause damage to some sensors. 10 dB of in-line external attenuation will bring the power level down to approximately 100 mW, within the sensor’s range. Adding a Offset Value of -10 dB will remove the external attenuation from the displayed power level.
