110 FONIX FP35 Hearing Aid Analyzer
10. OSPL90 REF: frequency response of OSPL90 curve at reference frequency
(1600 or 2500 Hz). Select with [F3].
11. OSPL90 MAX: amplitude and frequency of the maximum output of the aid.
12. FOG CALC: target reference test gain.
13. FOG MEAS: measured reference test gain.
14. EIN: equivalent input noise measurement.
15. LIM: response limit level determined by taking the frequency response of the
RESP 50 (or 60) curve at the reference frequency and subtracting 15 dB.
F1: frequency at which the RESP 50 (or 60) curve crosses the response limit
level on the way up.
F2: frequency at which the RESP 50 (or 60) curve crosses the response limit
level on the way down.
16. TOT H DIST: total harmonic distortion measurements and the frequencies
and amplitudes at which they are taken.
17. Battery size and current measurement.
18. I/O CURVE: input/output curve at reference frequency (1600 or 2500 Hz).
Select with [F3].
