E8362/3/4C Option H85
Example: Making High Power Measurements with Option H85
Example: Making High Power Measurements with
Option H85
This section describes how to set up the analyzer to perform high power measurements.
Analyzers equipped with the Option H85 can be configured to measure high power devices.
This ability is useful if the required power for the device under test is greater than the
analyzer can provide, or if the maximum output power from an amplifier under test
exceeds safe input limits for a standard analyzer.
This 2-Port example of the high power procedure chooses an optimal power level of
−12 dBm for all receivers. You may choose to optimize your measurement performance by
using Table 1 through Table 7 on Page 4 through Page 9.
For all high power configurations, refer to the specifications listed in Table 1 through Table
8.
CAUTION Prior to powering-up the booster amplifier, it is highly recommended that the
user verify the RF power levels seen by the various elements of the test setup.
At high power levels an incorrect power level could permanently damage the
instrument. It is recommended that you do not operate components near
damage or maximum levels. The power levels should be kept at less than
3 dB, preferably 6 dB, below damage and maximum levels.
