Gain
Measures the maximum gain difference (in dB) between left
Difference
and right channels over the test frequency sweep.
Phase
Measures the maximum phase difference (in degrees) between
Difference
left and right channels over the test frequency sweep. The phase
difference is referenced to the left channel, so the phase
difference reading may be negative or positive.

TEK TEST: 95

The Tek:95 sequence provides a signal to measure ANSI Crosstalk. The View
Audio Test results for Tektronix Program 95 reports the following measure-
ments:
Insertion Gain Error (dB)
Sweep Max. Gain (dB)
Sweep Min. Gain (dB)
THD+N (at 400 Hz) (%)
Polarity
Stereo Channel Assignment
Crosstalk (into channel) (dB)
ANSI Crosstalk (dB)
ANSI SNR (weighted) (dB)
Gain Difference (dB)
Phase Difference (deg.)
NOTE. The ANSI Crosstalk measurement has a noise floor threshold; a result is
not displayed in the ANSI Crosstalk (dB) report line unless the measured ANSI
SNR (weighted) (dB) measurement is less than 100 dB in both channels.
