Acquire the Sign
al
Waveform Record
The instrument builds the waveform record through use of the following parameters:
Sample interv
al: The time between
recorded sample points. Adjust this
by turning the Horizontal Scale knob
or pushing Ac
quire and changing the
record length in the Acquire menu.
Record length: The number of samples
required to fill a waveform record. Set
this by push
ing the Acquire button and
using the lower and side menus.
Trigger point: The zero time reference in
a waveform 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.
Using FastAcq
FastAcq™ provides high-speed waveform capture. It is helpful in finding elusive signal anomalie s. Fast acquisition mode
reduc
es the dead time between waveform acquisitions, enabling the capture and display of transient events such as
glitches and runt pulses. Fast acquisition mode can also display waveform phenomena at an intensity that reflects their
rate of occurrence.
To use FastAcq:
1. Push Acquire.
