Chapter 1 Specifications
All specifications apply to 10X probe and SDS1000D Digital Storage Oscilloscopes. To verify that the oscilloscope meets specifications, the oscilloscope must first meet the following conditions:
The oscilloscope must have been operating continuously for thirty minutes within the
specified operating temperature.
You must perform the Do Self Cal operation, accessible through the Utility menu, if the
operating temperature changes by more than 5° C.
The oscilloscope must be within the factory calibration interval

General Inspecting
After receiving a new SDS1000D series oscilloscope, please inspect the instrument as follows:
1...Inspect the shipping container for damage.
Keep the damaged shipping container or cushioning material until the contents of the shipment
have been checked for completeness and the instrument has been checked mechanically and electrically.
2...Inspect the whole instrument.
In case there is any mechanical damage or defect, or the instrument does not operate properly
or fails performance tests, notify the SIGLENT Sales Representative.
If the shipping container is damaged, or the cushioning materials show signs of stress, notify
the carrier as well as the SIGLENT Sales Department. Keep the shipping materials for carrier’s inspection.
3...Check the accessories.
Accessories supplied with the instrument are listed below. If the contents are incomplete or
damaged, notify the SIGLENT Sales Representative.
Standard Accessories:
● Two pieces 1:1,(10:1) Passive Probes
● An User Manual
● A Certification
● A Guaranty Card
● An CD(including EasyScope3.0 computer software system)
A Power Cord that fits the standard of destination country
An USB Cable

Power-On Inspection
Normal operating voltage for DS1000CA series digital oscilloscope is the range of 100-240VRMS with the frequency from 45Hz to 440Hz. Connect one terminal of the power cord to the socket in left side of the oscilloscope and the other to the power source.
Picture 2-1 Connect power line
Press the button on top of oscilloscope, some keys on the front panel will be lighted for about 6 seconds until the normal display appears. And then you can operate the oscilloscope.
After power-on, the oscilloscope performs the self test automatically. After the test, press the “DEFAULT/SETUP” button, then recall the Factory settings.
