SDS800X HD Quick Start

General Safety Summary
Carefully read the following safety precautions to avoid any personal injury or
damage to the instrument and any products connected to it. To avoid potential
hazards, please use the instrument as specified.
Use Proper Power Cord
Only the power cord designed for the instrument and authorized by local
government regulations should be used.
Ground the Instrument
The instrument is grounded through the protective earth conductor of the power
cord. To avoid electric shock, please make certain the instrument is grounded
correctly before connecting its input or output terminals.
Connect the Signal Cable Correctly
The potential of the signal cable ground is equal to the earth ground. Do not connect
the signal wire to a high voltage.
Look Over All Terminals’ Ratings
To avoid fire or electric shock, please look over all ratings and sign instructions of
the instrument. Before connecting the instrument, please read the manual carefully
to gain more information about the ratings.
Use Proper Overvoltage Protection
Make sure that no overvoltage (such as that caused by a thunderstorm) can reachthe product, or else the operator might be exposed to the danger of electrical shock.
Electrostatic Prevention
Operate in an electrostatic-protected area environment to avoid damages induced
by static discharge. Always ground both the internal and external conductors of thecable to release a static charge before connecting.
Maintain Adequate Ventilation
Inadequate ventilation may cause an increase in temperature, which may eventually
damage the instrument. Maintain suitable ventilation and inspect the fan and intake
regularly.

General Care and Cleaning
Care
Do not store or leave the instrument in direct sunshine for extended periods of time.
To avoid damages to the instrument or probes, please do not expose them to fog,
liquid, or solvents.
Cleaning
Please perform the following steps to clean the instrument and probes regularly inaccordance with its operating conditions.
1. Disconnect the instrument from all power sources and then clean with a soft wet
cloth.
2. Clean the loose dust on the outside of the instrument and probe with a soft cloth.
When cleaning the LCD, take care to avoid scratching it.
To avoid damage to the surface of the instrument and probe, please do not use any
corrosive liquid or chemical cleansers.
Make sure that the instrument is completely dry before restarting it to avoid potential
short circuits or personal injury.

General Inspection
1. Inspect the shipping container
Keep the damaged shipping container or cushioning material until the contents ofthe shipment have been completely checked and the instrument has passed bothelectrical and mechanical tests.
The consigner or carrier will be responsible for damages to the instrument resulting
from shipment. SIGLENT would not provide free maintenance or replacement if the
instrument has been damaged in shipment.
2. Inspect the instrument
If there are instruments found damaged, defective or failure in electrical andmechanical tests, please contact SIGLENT.
3. Check the accessories
Please check the accessories according to the packing list. If the accessories areincomplete or damaged, please contact your SIGLENT sales representative.

Adjust the Supporting Legs
Adjust the supporting legs properly to use them as stands to tilt the oscilloscope
upwards for stable placement as well as easier operation and observation of the
instrument.

Connecting to Power Supply

Probe Compensation
All oscilloscope probes should be properly compensated before their first use withthe oscilloscope. A non-compensated or inadequately compensated probe may
cause inaccurate measurement. The following steps illustrate the proper probe
compensation procedure.
1. Use the probe to connect the CH1 Input Terminal and the Compensation Signal
Output Terminalon the front panel. Connect the ground alligator clip of theprobe to the “Ground Terminal” under the compensation signal output terminal.
2. Check the displayed waveforms and compare them with the following figure.

3. Use a nonmetallic flat-head screwdriver to adjust the low-frequency
compensation adjustment hole on the probe until the waveform matches the“Compensated Correctly” waveform above.

Calibration
Self Calibration
The oscilloscope is calibrated at the factory prior to being shipped. The calibration
is run at 23°C (±2°C) and is valid for temperatures 23 ±5°C. Within this temperature
range, the oscilloscope will meet all specifications once warmed up.
Touch

Utility >Menu> Maintenance>Self Calibration

Warm up the oscilloscope for at least 20 minutes prior to each use or calibration inorder for it to reach a stable operating temperature. Specifications are notguaranteed during the warm-up period.
Whenever the oscilloscope is used in an environment outside 23 ± 5 °C, or when it
has been more than one month since the previous calibration, a self-calibration isrecommended.
Quick Cal
When Quick Cal is enabled, the oscilloscope will initiate an ADC calibration
procedure when the ADC temperature changes by over 3 °C to avoid performancedrift. This procedure is quick enough not to affect the user experience but willinterrupt the acquisition procedure. It is recommended to disable it when capturinglong-duration waveforms or monitoring rare events without interruption. The default
status of Quick Cal is disabled.
Changing vertical scale or channel interleaving mode will initiate the same ADC
calibration procedure in the background. This is always enabled, regardless of thestatus of Quick Cal.
