Power Level Flatness Test Procedure
Power level flatness is checked by measuring the power level variation during a full band sweep in the step sweep mode.
1. Set up the MG362x1A as follows for a step sweep power level flatness test:
a. Reset the instrument by pressing 3-Line Icon | SETTINGS | RESET |RESET ALL. Upon reset, the FREQUENCY menu is displayed with frequency and power level set to default values.
b. Press FREQUENCY button to open the current frequency parameter for editing.
c. Set the frequency to the CW frequency in Table: Power Level Accuracy Test Record.
d. In the same menu screen, press the LEVEL button to open the current power level parameter for editing and set LEVEL to the maximum specified power level noted in the data sheet (use a fixed attenuator when measuring power levels above +19 dBm).
e. Press SWEEP | STEP to show the step sweep menu as shown below.

f. Set START to the lowest frequency of the instrument and set STOP to the highest frequency of the instrument for a full frequency sweep.
g. Set the DWELL TIME to 1 second, or to a time that is comfortable between recordings.
h. Set the NUMBER OF POINTS to 100.
2. Press the TRIGGER menu.
3. Press TRIGGER SWEEP button to start a sweep.
4. As the MG362x1A steps through the full frequency range, observe the maximum and minimum power meter readings and record the values on the test record. Verify that the variation (difference between the maximum and minimum readings) does not exceed the value noted in Table: Power Level Flatness Test Record. The sweep may be repeated as necessary by pressing the TRIGGER button.
