Generating Signals with the Synthesizer
T o Use External Diode Detector Leveling
5. A djust the synthesizer output power so that the desired power at the
output is attained.
F or example , assume that you are using a power splitter and you want 05
dBm at the output of the splitter . In this case , you must set the power at
the output to 05 dBm. P erform the following procedure to set the power
at the output to 05 dBm.
a. T emporarily connect the power meter and sensor at the output.
b. Press the 4 POWER LEVEL 5 key .
c. Rotate the knob until the power meter reads 05 dBm (disregard the
synthesizer power level reading).
d. Disconnect the power meter and sensor from the output and connect
the device under test (DUT).
Notes
1. When the 4 EXT DIODE 5 ke y is pressed, the synthesizer output power might change . Therefore ,
you might want to check the output power and readjust if necessary .
2. External diode detector leveling does not provide temperature compensation, thus, output level
recalibration might be required in environments that are not temperature stabilized.
3. External diode detector leveling does not provide proper compensation from square law to linear
regions of the detector . Therefore , power level changes ma y require output level recalibration.
