PERFORMANCE CRITERIA
5.1 Performance criteria
The performance criteria are based on the general criteria in the standard.
Performance criteria
Criterion A:
The equipment shall continue to operate as intended during the test. No change
of actual operating state (see below) is allowed as a result of the application of
the test.
of actual operating state (see below) is allowed as a result of the application of
the test.
Criterion B:
The equipment shall continue to operate as intended after the test. No loss of
function is allowed after the test when the apparatus is used as intended. No
change of actual operating state (see below) is allowed as a result of the
application of the test. During the test, degradation of performance is allowed.
function is allowed after the test when the apparatus is used as intended. No
change of actual operating state (see below) is allowed as a result of the
application of the test. During the test, degradation of performance is allowed.
Change of actual operating state of the EUT:
The EUT stops amplify the signal from the generator.
The criterion concerning acceptable sound interference is a wanted to unwanted audio signal
ratio of
ratio of
40 dB at a wanted audio signal level of 50 mW.
5.2 Performance verification
The test engineer observed the performance of the EUT directly or via video cameras.
The audio output power was checked via software T80-K1 and speakers connected to the EUT
respectively.
The audio output was checked via a microphone connected to a measuring amplifier.

6.9 Measurement uncertainty
The measurement uncertainty for S1 is: ± 1,2 dB.
The measurement uncertainty for S2 is: ± 2,1 dB.
The measurement uncertainty for S3 is: ± 2,1dB.
The measurement uncertainty for S4 is: ± 3,3 dB.
The measurement uncertainty for S2 is: ± 2,1 dB.
The measurement uncertainty for S3 is: ± 2,1dB.
The measurement uncertainty for S4 is: ± 3,3 dB.
Measurement uncertainty is calculated in accordance with EA-4 /02:1997. The measurement
uncertainty is given with a confidence of 95%. The uncertainty calculations exclude influence of
phenomena like inhomogenity of the electric field intensity.
