Requirement for Performance Tests
Performance tests are used as preventive maintenance to prevent degradation of the
MS8608A/MS8609A performance before it occurs.
Use the performance tests whenever necessary such as at acceptance and periodic
inspection of the MS8608A/MS8609A and to verify performance after repair. Execute
the performance tests listed below to verify the MS8608A/MS8609A performance at
acceptance inspection, periodic inspection and after repair.
• Reference oscillator frequency stability
• Rubidium reference oscillator frequency stability
• Frequency readout accuracy
• Frequency span readout accuracy
• Resolution bandwidth and selectivity
• Sideband phase noise
• Frequency measurement accuracy
• Amplitude display linearity
• Frequency response
• Reference level accuracy
• Average noise level
• Second harmonic distortion
• Resolution bandwidth (RBW) switching uncertainty
• Input attenuator switching uncertainty
• Sweep time and time span accuracy
Execute the performance tests at regular intervals as preventive maintenance for
important evaluation items.
We recommend that the performance be inspected regularly once or twice a year.
If the specifications are not met at the performance tests, please contact Anritsu
Corporation.
