6.3.4. RNGE Æ MODE Æ DUAL: CONFIGURING THE M300EU ANALYZER
FOR DUAL RANGE MODE
DUAL range mode allows the A1 and A2 outputs to be configured with separate reporting range spans as well
as separate electronic signal levels. The analyzer software calls these two ranges LOW and HI.
• The LOW range setting corresponds with the analog output labeled A1 on the rear panel of the
instrument and is viewable via the test function RANGE 1.
• The HIGH range setting corresponds with the A2 output and is viewable via the test function RANGE 2.
• While the software labels these two ranges as LOW and HI, when in DUAL mode their upper limits need
not conform to that convention. The upper span limit of the LOW/RANGE1 can be a higher number than
that of HI/RANGE 2
To set the ranges press following keystroke sequence:
