8.5 Performance test
This section describes, among principal test items, those items which can be tested without using
special/elaborate jigs or measurement equipment. Adjustment and/or repair is needed when you
have any test results that do not meet the specifications.
Ask NF Corporation for more detailed tests, calibrations and/or repairs.
8.5.1 Test equipment
The following test equipment and cables are required for performance tests:
Frequency counter: Accuracy: 110
-6
or better
Multi-meter (the following measurement shall be possible):
AC voltage: Accuracy: 0.1 % for 100 mV - 10 V and 100 Hz - 10 kHz.
DC voltage: Accuracy: 0.1 % for 100 mV - 10 V
Wideband multi-meter (the following measurement shall be possible):
AC voltage: Accuracy: 0.5 % for 100 mV - 10 V and 100 kHz - 200 kHz
Accuracy: 1 % for 100 mV - 10 V and 200 kHz - 1 MHz
Accuracy: 5 % for 100 mV - 10 V and 1 MHz – 15 MHz
Distortion meter: 0.1 % or better for full-scale
Others: BNC-BNC coaxial cable, T-type divider, etc.
8.5.2 Pretest preparations
a) Confirmation of test environment
Perform the test under the following conditions:
Ambient temperature: +18 - +28 ºC Ambient humidity: 25 - 75 %RH
Power supply voltage: 90 - 132 VAC or 180 - 250 VAC
b) Confirmation of functions/operations
Check and confirm important functions, before the test, in an abbreviated manner according
to “2.5 Quick function checking”.
c) Warm-up
Leave the instrument for at least one (1) hour after turning the power on so that the internal
temperature becomes stabilized.
Perform/execute calibration by all means before the test. The performance of the FRA5087
is specified on the basis of the status right after calibration.
