Automated Test Sequences 113
Figure 5.1.6—ANSI 03 test results, Frequency Response Screen
9. RTG Measured: Measured reference test gain
10. EQ Inp Noise: Equivalent input noise measurement
11. Resp Limit: The response limit level is determined by taking the three fre
-
quency average of the RESP 50 curve and subtracting 20 dB.
F1 is where the RESP 50 curve crosses the response limit level on the way
up.
F2 is where the RESP 50 curve crosses the response limit level on the way
down.
12. HFA/SPA: Three frequency average chosen in the MENU.
13. TDH: total harmonic distortion measurements and the frequencies and
amplitudes at which they are taken.
14. HFA/SPA-SPLITS: Three-frequency average of the telecoil frequency
response curve.
15. RSETS: The difference between the HFA/SPA of the microphone response
curve and the telecoil response curve.
16. Battery Current measurement
17. I/O curves: the input/output measurements taken of AGC aids. Only selected
frequencies are tested.
