Maximum power to the RF IN port is 26 dBm. With the PORT 1 or PORT 2
SWITCH/COUPLER ports connected, the approximate loss from RF IN to either test
PORT is 6 dB at 3 GHz, and 8 dB at 6 GHz. The approximate loss for the Option 075 is
8 dB at 3 GHz.
Maximum power to PORT 2 from the DUT is 2 watts or 33 dBm. Attenuators need to be
added to the A and B sampler ports to reduce the power to the samplers. An isolator was
added to the PORT 2 SWITCH/COUPLER ports to reduce power to the transfer switch.
Maximum power to the transfer switch is 26 dBm. Some compression may occur above
−123 dBm.
NOTE Isolators must be inserted so that maximum isolation is achieved from the
COUPLER to the SWITCH ports. Refer to the isolators' manufacturer
specifications for more information.
High Power Configuration Three
Figure 1-55 shows the external high power configuration. With this setup you can develop
your own high power configuration. This solution can be used for measurements in the
forward direction as long as the maximum power limits of the analyzer are not exceeded.
This configuration offers higher power capabilities.
NOTE This is only an example configuration for high power applications. Actual
device values need to be determined for each individual application.
