Agilent Technologies 8935 series e6380a manual Level value to avoid damage to that device

Overview of the Test Set’s Built-In Tools

		Using the RF Tools Program
	6.	Position the cursor at DUPLEX OUT Level in dBm and select it.
		Enter the power level, − 54 to +10 dBm, at which the test should be
		conducted. If you are testing a power sensitive device, enter a low
		level value to avoid damage to that device.
	Damage may result if the power input to the Test Set’s ANT IN port
CAUTION
	exceeds 60 mW (which is equivalent to 18 dBm). Damage may also
	result to the unit-under-test if it is overdriven by the DUPLEX OUT
	power level. To avoid damage to the unit under test, enter a low power
	level for the DUPLEX OUT level in dBm parameter.
	7.	Press k1 (Begin Tst).

8.A setup screen appears with a diagram of the necessary connections, similar to the Calibration Setup of Figure 1-2. This test requires two 6-dB pads (attenuators). The pads are put on the Test Set’s ANT IN and DUPLEX OUT ports to reduce impedance mismatch error at these ports. A reference level is obtained by connecting a short calibration cable between the pads on the DUPLEX OUT and ANT IN ports. Set up the hardware, then press k1 (Proceed) or the knob to continue.

9.Another setup screen appears similar to the Measurement Setup of Figure 4-5. Attach the device to be tested between the calibration cable and one of the pads. In this step, a measurement is made of the additional gain from the reference level. Press k1 (Proceed) or the knob to continue.
