Turn m u ltipur p
ose knob a to s elect the search
type: Edge, Pulse Width, R unt, Logic, Setup &
Hold, Rise/Fall Time, or Bus.
On the screen, hollow triangles show the
location of automatic marks and solid
triangles show the custom (user-defined)
locations. These appear on both normal and
zoomed waveform views.
4. You can quickly investigate your waveform
by moving from search mark to search mark
with the next ( ) and previous ()arrow
buttons. No other adjustments are needed.
Quick Tips.
You can copy trigger settings to search for other locations in your acquired waveform that meet the trigger conditions.
You can also copy search settings to your trigger.
Custom (User) marks are saved with the waveform when the waveform is saved and when the setup is saved.
Automatic s earch marks are not saved with the waveform when the waveform is saved. However, you can easily
recap
ture them by reusing the search function.
The se
arch criteria are saved in the saved setup.
The Wa
ve Inspector includes the following search capabilities:
Sear
ch
Desc
ription
Edge
Sear
ches for edges (rising or falling) with a user-specified threshold level.
Pulse Width
Sea
rches for positive or negative pulse widths that are >, <, =, or a user specified pulse
width.
Run
t
Searches for positive or negative pulses that cross one amplitude threshold but fail to cross
a second threshold before crossing the first again. Search for all runt pulses or only those
wi
th a duration >, <, =, or a user specified time.
Logic
Se
arch for a logic pattern (AND or NAND) across multiple waveforms with each input set to
either High, Low, o r D on't C are. Search for when the event goes true, goes false, or stays
validfor>,<,=,or a user specified time. Additionally, you can define one of the inputs as
a
clock for synchronous (state) searches.
S
etup & Hold
S
earch for violations of user specified Setup and Hold times.
