12. Measurement re
adouts show the
selected measurements. You can select
up to eight measurements to display at
one time.
A
symbol appears instead of the
expected numerical measurement if a
vertical cli
pping condition exists. Part
of the waveform is above or below the
display. To obtain a proper numerical
measurement
, turn the vertical scale
and position knobs to make all of the
waveform appear in the display.
13. The auxiliary waveform readouts show
the vertic
al and horizontal scale factors
of the math and reference waveforms.
14. The chann
el readout shows the channel
scale factor (per division), coupling,
invert, and bandwidth status. Adjust
with the V
ertical Scale knob and in the
channel 1, 2, 3,or4 menus.
15. For analog channels, the waveform
baseline indicator shows the zero-volt
level of
a waveform, assuming you have
not used any offset. The icon colors
correspond to the waveform colors.
16. For digital channels (MSO4000B Series
only), the baseline indicators point to
the high and low levels. The i ndicator
colors follow the color code used on
resistors. The D0 indicator is black, the
D1 indicator is brown, the D2 indicator is
red, and so on.
17. The group icon indicates when
digital channels are grouped
(MSO4000B Series only).
