Chapter 4 Performance Test
4-2
4.1 Overview of Performance Test
Performance tests are performed as part of preventive maintenance in
order to prevent degradation of the performance of the equipment.
Use performance tests when required for acceptance inspection, routine
inspection and performance verification after repairs. Use performance
tests when necessary for acceptance inspection, routine inspection and
performance verification after repairs. Also perform the following
performance tests for acceptance inspection, routine inspection and
performance verification after repairs of the equipment.
RF Performance Test
● Residual FM, Residual
M, Residual AM
With MS2830A-018/118 installed.
Audio Performance Test
● Input level accuracy
● Input distortion
● Crosstalk
● Output level accuracy
● Total harmonic distortion + Noise
Perform items deemed critical at regular intervals as preventive
maintenance. A cycle for routine tests of once or twice a year is
recommended.
If items that do not meet the required level are detected during
performance testing, contact an Anritsu Service and Sales office. Contact
information is available in a separate file (for the PDF version), and on
the last page of this manual (for the printed version).
CAUTION
Warm up the device to be tested and the measuring
instruments for at least 30 minutes except if specified
otherwise, in order to stabilize them sufficiently before
running performance tests. Maximum measurement
accuracy requires, in addition to the above, conducting
performance tests under ambient temperatures and with
little AC power supply voltage fluctuations, as well as the
absence of noise, vibrations, dust, humidity and other
problems.
