Frequency Synthesis Test
The following test verifies that the CW frequency output of the MG362x1A under test is within tolerance. Table: Frequency Synthesis Test Record contains a standard test record that you can copy and use to record test results for this test.
Setup for Frequency Synthesis Test
The following procedure tests the tolerance of the CW frequency output.
1. Connect the equipment shown in Figure: Setup for Frequency Synthesis Test as follows:
a. Connect the MG362x1A rear panel 10 MHz REF OUT to the Frequency Counter 10 MHz External Reference input.
b. Connect the MG362x1A RF OUTPUT to the Frequency Counter RF Input 1.
2. Set up the MG362x1A as follows:
a. Upon preset, the FREQUENCY menu is displayed with frequency and set to default values.
b. Press FREQUENCY to open the current frequency parameter for editing.
c. Set the first test frequency in Table: Frequency Synthesis Test Record.
3. Record the frequency counter reading on the test record and calculate the difference between the test frequency and the measured value.
4. Verify that the calculated difference meets specifications.
Note 
The frequency counter reading is typically within ±1 Hz. Differences of a few hertz can be caused by noise or counter limitations. Differences of more than ±10 Hz indicate a frequency synthesis problem.
5. Set FREQUENCY to the next test frequency.
6. Record the frequency counter reading and calculate the difference between the test frequency and the measured value.
7. Repeat steps 5 and 6 until all of the test frequencies in Table: Frequency Synthesis Test Record have been recorded.
