To Choose an Acquisition Mode:
1
Press SHIFT, and then press ACQUIRE MENU.
Press Mode in the main menu.

3
From the side menu, select an acquisition mode that will
serve your application.
How the Acquisition Modes Work:
Incoming
signal
Samples acquired for
each waveform data
point interval
Acquisition mode
processes samples
Sample
Uses first sample in interval
Displayed
data point
Waveform
drawn on CRT
Use for fastest acquisition rate.
Sample is the default mode.
Use to reveal aliasing and for
glitch detection.
Single
waveform
acquisition
Multiple
waveform
acquisitions
Peak Detect
Uses highest and lowest
samples in interval
Not Available on TDS 600C
Hi Res
Calculates average of
samples in interval
Envelope
Uses highest and lowest
samples over many acquisitions
Average
Peak Detect provides the
benefits of enveloping with
speed of single acquisition.
Use to reduce apparent noise.
Hi Res provides the benefits of
averaging with the speed of
single acquisition.
Use to reveal the noise band
around the signal.
Use to reduce apparent noise in
a repetitive signal.
Calculates average value
over many acquisitions

Press Format in the main menu, and select a hardcopy
format from the side menu.
Press HARDCOPY anytime to save a copy of the current
screen to a unique file in the oscilloscope file system.
To Perform Other File System Operations:
H Press SA VE/RECALL WAVEFORM, and use the menu buttons to save a waveform to a file or recall it from a file.
H Press SA VE/RECALL SETUP, and use the menu buttons to save a setup to a file or recall it from a file.
H Press File Utilities in the Save/Recall Waveform, Save/Recall Setup, or Hardcopy menus to access utilities that create
directories, copy files, and do other operations in the oscilloscope file system.
To Preview a Waveform:
1
Press ZOOM.
2
Press Mode in the main menu. Then press Preview in the side menu to turn on Dual Window Zoom.
Upper graticule zooms the boxed area
on the selected waveform.
Lower graticule displays the selected waveform
unzoomed with the zoomed area in box.
3
Use the Selected Graticule menu to select the upper or lower waveform. Use the vertical and horizontal knobs
to adjust the waveform in the graticule you select.
To Capture Infrequent Events (TDS 500D & 700D Models):
Press DPO to toggle between DPO and Normal waveform capture
rates.
When in DPO mode:
H Waveforms displayed are updated thousands of times
faster than normal.
H Very brief changes in waveforms are captured.
H Certain features, such as Limit Testing, Math Waveforms, Zoom, and
record lengths longer than 500 points, are not available.
