Measuring High-Power Devices with Option 004
The HP 8517B, Option 004 test set enables devices with output power up to 30 dBm (1 watt) to be measured at Port 2, without adding external attenuators. Reverse dynamic range (S12) degrades by approximately 3 dB.
When measuring devices having greater than +17 dBm output power, you must use the Port 2 step attenuator to decrease the power to ≤+17 dBm.
The step attenuator has to be set during calibration for the value needed during device measurements. However, this setting may cause inadequate power level during calibration. Refer to “Changing Signal Path States After System Calibration” on page
