SECTION 6
PERFORMANCE TESTS
Requirement for Performance Tests
Performance tests are used as preventive maintenance to prevent degradation of the MS2665C/67C/68C
performance before it occurs.
Use the performance tests whenever necessary such as at acceptance and periodic inspection of the MS2665C/
67C/68C and to verify performance after repair. Execute the performance tests listed below to verify the
MS2665C/67C/68C performance at acceptance inspection, periodic inspection and after repair.
• 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.
