DSTouch
Ultra-portable Touchscreen Oscilloscope
Quick Start Guide
®
0.Introduction
DSTouch oscilloscope e combines the high performance of a des
ktop oscilloscope with the touch screen experience of a smartphone. I
n terms of performance, it utilizes FPGA-based hardware waveform en
gine architecture, and a large storage depth based on DRAM. In terms
of operation, it creatively designed a set of "single-finger touch" metho
ds, simplifying all functions into 1-3 tap and swipe operations
DSTouch oscilloscope is equipped with a built-in high-capacity lit
hium battery, making it an ideal palm-sized portable instrument.
1. Power On/Off
To prevent accidental power on/off caused by touching the powe
r button, DSTouch provides a long press power button to switch on/of
f and touch screen shutdown function
Button Power On/Off:
Touch Power Off（→ → ）:
2. Run/Stop
DSTouch oscilloscope has physical and touch buttons for easy ru
n/stop control, meeting common usage needs.
Button Run/Stop:
Touch Run/Stop（ ）:
3. Probe
BNC interface on DSTouch allows compatibility with all standard
BNC probes, expanding usability.
Probe compensation:
Connect probe to oscilloscope's compensation reference signal.
Adjust probe compensation capacitor until waveform matches
desired display.
Probe attenuation
Match probe attenuation w
ith oscilloscope channel probe r
atio during use.
4. Autoset
DSTouch Oscilloscopes offer powerful autoset features for conve
nient and stable display of measured waveforms with a single button
press.
Button Autoset:
Touch Autoset（→）:
5. Auto measurement
DSTouch oscilloscope simplifies adding/removing measurement
s on traditional scopes. Just a few taps to add/delete auto measurem
ents from a menu of 20 commonly used options.

6. Trigger
DSTouch oscilloscope has reliable hardware triggering and
adjustable sensitivity and hold-off time.
Trigger level（→）：
Trigger Options（→</>）：
Trigger Sensitivity: Adjust the trigger level hysteresis window.
Smaller values provide more sensitive triggering, while larger values
increase stability in noisy signals.
Hold-off time: Delay period after each trigger before the trigger cir
cuit resumes operation. It prevents triggering during this interval, even
if the trigger conditions are met. Setting a reasonable hold-off time all
ows stable capture and analysis of burst signal waveforms, commonl
y seen in communication signals with alternating "idle" and "transmiss
ion" patterns.

9. Save/Load session and file operations
DSTouch oscilloscope offers 9 one-click switching sessions for
different testing scenarios, eliminating the need to repeatedly adjust o
scilloscope parameters.
The internal disk provided by the DSTouch oscilloscope can be
used for screenshots and connected to a computer as a U-disk
function. Firmware upgrades and other operations can be completed
through U-disk mode.

user-related personalized settings will be cleared.
10. Quick Menu
DSTouch oscilloscope provides Quick Menu. Most operations can
be completed with the thumb while holding the oscilloscope with the
left hand, freeing up the other hand to fix the probe and test points.
Long-press on left can bring up the Quick Menu. Switch settings
for vertical, horizontal, and trigger options. Adjust settings by sliding in
the waveform area.
11. More Features
DSTouch oscilloscope offers additional practical features includi
ng FFT, protocol decoders, cursor measurements, X-Y mode, persisten
ce function, auto calibration, and signal generator, etc.
