to the DS-1000 or any equipment connected to it.
Symbol definitions:
This symbol indicates that the manual should be referred to.
WARNING
WARNING denotes that, if not correctly performed or
adhered to, could result in injury or loss of life. Do not
proceed beyond a warning until the indicated conditions are
fully understood and met.
CAUTION

What is the DS-1000 series digital storage oscilloscope?
The DS-1000 series is a PC-based, pocket-sized digital storage oscilloscope (DSO)
designed and manufactured by Acute Technology Inc. It has three models: DS-1002,
DS-1102, and DS-1202 with the same functionality as its stand-alone peers. Detailed
specifications are listed on the next page.
Easy to carry: It is very portable; notebook co-operability makes mobility easy.
Easy to use: Leverage the storage capacity and power of applications within a
PC/Notebook.

Application Installation
1. When you want to install the latest version of the DS-1000 Application (AP)
software, please REMOVE the current DS-1000 AP in your PC. This will
NOT change any existing project file(s) or environment parameter(s).
2. Insert the installation CD into the CD-ROM drive.
3. Double click the CD-ROM drive icon to enter the auto-installation procedure.
If there is no response, run setup.exe from the CD-ROM root directory. The CD
has other application software for other Acute products, such as logic analyzer
and programmable data generator. The software, if installed, will enter DEMO
mode since no such hardware exists.
4. Change the default folder if you want to use another directory.
5. Start the DSO software installation.
6. Once the installation is completed, you may find the DSO icon either on the
Desktop or in the Programs group. You may double click either icon to start
the DSO AP.
7. If you enter “DEMO Mode” when you launch the DS-1000 AP, this means that
some problem has occurred. Please contact your dealer or email us at
[email protected].

Quick Start: (Calibration)
1. Connect the two probes to the DS-1000’s Channel 1 and Channel 2 BNC connectors.
2. Switch the Probe to “x10”.
3. Connect the two probe ground leads to the DS-1000’s ground terminal.
4. Connect the two probe tips to the DS-1000’s “Probe Comp. (3.3V)” terminal.
5. Launch the DSO AP from Windows Desktop.
6. Push the “Auto Set” button.
7. If you see the waveforms shown below:
Adjust the trimmer located in the probe’s BNC plug to obtain a flat-top square
waveform as shown below.
8. Switch the Probe to the “REF” position.
9. Push the “Utility” button.
10. Push “Calibration” Function Button.
11. During calibration, the DSO AP will ask you to switch the Probe to”x10”.
12. Once calibration has finished, you can change the time base or vertical division to
check the result of the calibration.

Screen
Channel Switch Button
There are 6 channels, CH1, CH2…, CH6 on the upper right corner of the
panel as shown above. When you are operating one DSO-1000, only CH1
and CH2 are available and the rest of the channel buttons, with gray font,
are not available like CH3 - CH6 as shown on the left. (CH3, CH4)/(CH3,
CH4, CH5, CH6) are available if two/three of the DSO-1000 units are
stacked. CH1, with gray button and black font, as shown on the left, is
available but not activated. If you click on the CH2 button, its functions
will be activated and its color turns to blue as shown on the left. Each
activated channel button has its own color, which is identical to that of the
waveform of the channel.

VOLTS/DIV Knob
The VOLTS/DIV knob is used to change the vertical voltage scale. On the screen’s
lower-left corner, a voltage scale (for each division is) displayed. There are 8
vertical divisions on the screen. For example, if the corner displays “CH1 2.00V”,
this means that the voltage scale is 2 Volts for each vertical division and the voltage
distance from top to bottom of all 8 divisions on the screen is 16 Volts. There are
two small buttons near the VOLTS/DIV knob; one is “-“(zoom out), the other is “+”
(zoom in). You can click your mouse’s left button (or “-“) or the right button (or
“+”) on the VOLTS/DIV knob to increase or decrease the voltage scale. Also, the
mouse wheel (if so equipped) can be used to adjust the voltage scale even faster.
SEC/DIV Knob
The SEC/DIV knob is used to change the time scale. On the upper center of the
screen, a time scale is displayed. This represents each horizontal time division, set
to 50us in the example above. You can move the mouse to the SEC/DIV knob and
then click the left or right button of the mouse to increase or decrease the time scale.
If your mouse has a wheel, you can use the wheel to quickly adjust the time scale.
There are two small buttons near the SEC/DIV knob. One is “–”, the other is “+”.
These two small buttons are used for adjusting the time scale if the mouse has only
one button.
On the screen’s upper-center edge, a time scale for each division is displayed.
There are 10 divisions on the screen. For example, if the time scale displays “M 50µs”,
this means that the time scale is 50 µs for each horizontal division. There are two
small buttons near the SEC/DIV knob; one is “-“(zoom out), the other is “+” (zoom
in). You can click your mouse’s left button (or “-“) or the right button (or “+”) on
the SEC/DIV knob to increase or decrease the time scale. Also, the mouse wheel (if
so equipped) can be used to adjust the time scale even faster.
Operations

Main Function Button
There are seven main function buttons: Trigger, Display, Cursor, Measure, Utility,
Save/Recall, and Acquire under the Full mode screen. When you disconnect the
DS-1000 from your PC and launch the DSO AP, the program automatically changes
to Demo mode and the Acquire button becomes the Demo button. If you still want
to use the Acquire function under Demo mode, please switch the DSO AP to Skin
mode, then you can find the Acquire function under the pull-down function menu
on upper right corner.
Sub-Function Button
There are ten sub-function buttons, which work in conjunction with the seven main
function buttons. However, not all sub functions are available in each main
function. You may trigger each sub function by clicking the left or right button of
the mouse. For example, [if you] click the right button of the mouse under the sub
function for probe type, the sub function will be activated in this order: “x1”, “x10”,
“x100”. Clicking the right button under the same sub function activates the sub
function in the opposite order: “x100”, “x10” or “x1”.
RUN/STOP Button
The Run/Stop button runs or stops the signal acquisition process. The DS-1000
also has a hot key RUN/STOP button, which performs the same function. This
button is on the side of the DS-1000 units.
FORCE TRIGGER Button
When the TRIGGER is set to Normal or Single Shot mode and the unit is not
triggered, the “FORCE TRIGGER” button is used to force the DS-1000 to trigger.
AUTOSET Button
DS-1000 will automatically adjust its Voltage, Time, and Trigger parameters for the

─
20 ─
signals under test to display their waveforms. However, it could take some time
for the DS-1000 to do so due to the many possible combinations of DS-1000
parameters and signal characteristics. So, the “AUTOSET” button is used to adjust
Voltage, Time, and Trigger parameters of the DS-1000 for tested signals and display
the signals’ waveform more quickly than may be achieved manually. The
“AUTOSET” button, when pushed, will find the parameters of the signal applied to
the active channel. For example, if the “Channel Switch” button is set to CH1, then
the Voltage, Time, and Trigger parameters of the CH1 signal(s) will be the
benchmark parameters used for the “AUTOSET” function.
Set to 50% Button
Pushing the “Set to 50%” button will cause the DS-1000 to fine tune the trigger level
to the mean voltage of the trigger signal.
Hard Copy Button
The “Hard Copy” button can be used to print (hard copy) the waveform on the
screen to the default printer. Also, you may generate output with different
parameters in “Preview” under the ”Export” sub-function of the Utility main
function.
