Applications
Peak-to-Peak Voltage
With
~
V turned
on
and
VOL TS/DIV VAR fully clockwise, align the
~
REF
cursor
with the bottom of a waveform and align the
~
cursor with the top. The readout
shows the equivalent voltage between the cursors anywhere
on
a waveform.
Accuracy
is
degraded at frequencies approaching the instrument bandwidth.
Absolute Voltages
1.
Position the waveform
as
desired for convenient viewing, with VOL TS/DIV
VAR fully
clockwise
and
with VOL TS/DIV set for the largest usable display
amplitude.
2.
Momentarily switch Input Coupling to
GND
and
align the
~
REF
cursor with
the trace.
3.
Switch Input Coupling to
DC
and
set the
~
cursor to the point of interest.
