amplitude with the power meter. Use the formula below to calculate the system error. System
Error = Power Meter Measurement Value - (+10 dBm - Attenuation of the
Program-controlled Attenuator) - System Error Reference Value. Record the calculation
result in the test record form.
6. Disconnect the program-controlled attenuator and the power sensor. Connect the output of the
program-controlled attenuator to the RF input terminal of the spectrum analyzer, as shown in
Figure 2-8 (b).
7. Set the attenuation of the program-controlled attenuator to 20 dB.
8. Configure the spectrum analyzer:
a) Set the center frequency to 50 MHz.
b) Set the span to 10 kHz.
c) Set the reference level to 0 dBm.
d) Set the input attenuation to 10 dB.
e) Set the resolution bandwidth to 1 kHz, and set the video bandwidth to 10 Hz.
f) Set the sweep time mode to Auto; set the sweep time rule to Accuracy.
9. Press Single and wait for the instrument to finish a sweep. Press Peak to find the maximum
peak. Use the formula below to calculate the global error reference value. Global Error
Reference Value = Maximum Peak of the Spectrum Analyzer - (+10 dBm - 20 dB).
Record the calculation result in the test record form.
10. Set the attenuation of the program-controlled attenuator, the reference level of the spectrum
analyzer, and the attenuation of the internal attenuator according to the Test Record Form.
For each group of settings, press Single and wait for the instrument to finish a sweep. Press
Peak to find the maximum peak. Use the formula below to calculate the global error. Global
Error = Maximum Peak of the Spectrum Analyzer - (+10 dBm - Attenuation of the
Program-controlled Attenuator) - Global Error Reference Value. Record the calculation
result in the test record form.
11. Use the formula Uncertainty = |Global Error - System Error| to calculate the uncertainty.
Compare the calculation result with the specification.
