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: 1  10
-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.
