Amplitude Accuracy Across Frequency Verification

Component Characterization:.
Figure 2-11. Fixed Level with Varying Frequency – Component Characterization Setup
1. Connect both MA2442D power sensors to the power meter and calibrate the sensors.
2. Connect the equipment as shown in
3. Set the MG3692x Frequency to 10.1 MHz.
4. Set the power meter to display both Channel A and Channel B. Press the Sensor key, the Cal Factor soft
key, and then the Freq soft key. Use the keypad to enter the value matching the frequency of MG3692x
as the input signal frequency, which sets the power meter to the proper power sensor calibration factor.
Repeat for Channel B. Press the System key to display the power reading.
5. Adjust the MG3692x output level so that the Sensor A reading is –2 dBm ± 0.1 dB.
6. Record the Sensor B reading into the –2 dBm column in
Level with Varying Frequency" on page
7. Adjust the MG3692x output level so that the Sensor A reading is –30 dBm ± 0.1 dB.
8. Record the Sensor B reading into the –30 dBm column in
9. Repeat Step 3 through Step
