AUDIO
Two analog stereo pairs (L1, R1; L2, R2), user selectable from among
the audio input pairs, are available at a push-on, mating connector (with
audio option installed).
AUDIO OUTPUT SIGNAL
LEVEL
+4 dBm (600Ω balanced) ± 1 dB for any situation where the input level
is equal to the selected reference level, except for the selection of the
dBfs scale. When the dBfs scale is selected, the analog output level is
-4 dBm ± 1 dB with a -20 dBfs input regardless of the selected
reference.
AUDIO METER DISPLAY
Bar graph displays of L1, R1, L2, R2 audio channels
AUDIO METER ACCURACY
Non-Zoomed Display
 ± 1 dB for readings down to -26 dB
 ± 3 dB for readings of -30 dB and below
Zoomed Display
± 0.5 dB
AUDIO PHASE DIFFERENCE
INDICATION
Differential phase displays for L1, R1 and L2, R2 are provided covering
the range of 0° to 180°
Interface
