3-11 POWER LEVEL
ACCURACY AND
FLATNESS TESTS
The following tests can be used to verify that the 682XXB/683XXB
meets its power level specifications. Power level verification testing is
divided into two parts—power level accuracy tests and power level
flatness tests.
TestSetup Connect the equipment, shown in Figure 3-6, as fol-
lows:
1. Calibrate the Power Meter with the Power Sen-
sor.
2. Connect the Power Sensor to the RF OUTPUT of
the 682XXB/683XXB.
NOTE
For £40 GHz models, use the K (male) to
2.4 mm (female) adapter to connect the
Power Sensor to the RF OUTPUT connec-
tor.
3. Connect the 682XXB/683XXB rear panel HORIZ
OUT to the Oscilloscope CH.1 input (X input).
NOTE
During this test it will be necessary to
adjust the Power Meter’s CAL FACTOR%
setting as applicable for the frequency
being tested.
