E8362/3/4C Option H85
Example: Making High Power Measurements with Option H85
2. Set the receiver attenuator to the value calculated in the previous step (rounding off to
the highest 5 dB step). Setting the receiver attenuation will establish the internal
attenuation. In the Stimulus drop-down menu select Power > Power and Attenuators.
In the application window, select Receiver Attenuators. Set Receiver A to [10 dB] and
Receiver B to [20 dB] and press OK. Power levels greater than +35 dBm will require
additional attenuation between Port 2 access ports CPLR ARM and RCVR B IN.
Figure 11 Receiver Attenuators
CAUTION PNA Option 016 adds a 35 dB step attenuator with 5 dB resolution to A and B
receivers. Power measurements to Test Ports 1 and 2 above +35 dBm will
require additional attenuation. Add the appropriate amount of attenuation
that will keep the coupler arm output power below the maximum receiver
inputs. Refer to Table 1 on page 4 to optimize the power levels in the receiver.
CAUTION From this point forward, do not press Preset unless you have turned off the
booster amplifier(s), or have renamed and saved this state as User Preset.
Pressing Preset will return the analyzer to its default power level and default
internal attenuator settings. This increase in power may result in damage to
the DUT or analyzer.
3. Turn On the booster amplifier.
