MSO4000B and D
PO4000B Series
oscilloscopes use real-time sampling. In
real-time sampling, the instrument digitizes
all of the poin
ts it acquires using a single
trigger event.
Sampling rate
Waveform R
ecord
The instrument builds the waveform record through use of the following parameters:
Sample interval: The time between
recorded sample points. Adjust this
by turnin
gtheHorizontal Scale knob
or pushing Acquire and changing the
record length in the Acquire menu.
Record length: The number of samples
require
dtofill a waveform record. Set
this by pushing Acquire and using the
resulting lower and side menu menus.
Trigger point: The zero time reference in
awave
form record. It is shown on the
screen by an orange T.
Horizontal position: When Delay Mode
is on, this is the time from the trigger
point to the expansion point. Adjust this
by turning the Horizontal Position knob.
Use a positive time to acquire the record
after the trigger point. Use a negative
time to acquire it before the trigger point.
Expansion point: The point that the
horizontal scale expands and contracts
around. It is shown by an orange triangle.
