Audio analyzer specifications
–– All specifications for the audio analyzer apply to signals pres-
ent at test set’s AUDIO IN ports.
–– Audio analyzer de-emphasis: 750 μs, de-emphasis settable
as off or on
–– Audio analyzer expander: Settable as off or on with reference
level setting of 10 mV to 10 V
–– Audio analyzer filters: Settable choices of none, C-message,
50 Hz to 15 kHz band pass, 300 Hz to 15 kHz band pass, or
100 Hz bandwidth tunable band pass tunable over 300 Hz to
15 kHz
