3.1 Check that the trigger source channel is consistent with the waveform being viewed
3.2 Manually adjust the LEVEL trigger knob to see whether the waveform is stable.
3.3 Use AUTO to adjust the waveform automatically to determine whether the waveform is stable
3.4 Adjust time base, rule out false-wave interference (such as alias displayed waveforms)

First, check the power cord and power strip for damage. Check the power switch on the instrument to make sure it is open (SDS1000CFL series has a power switch and a power protection switch). Is the power light illuminated?
Is the fan operating? If the fan works, the machine is powered on. If everything is normal but the oscilloscope still does not turn on, please contact your nearest SIGLENT dealer.

The term “div” for most SIGLENT specifications is equal to the Vertical Scale value (Commonly shown in units of Volts/div).
Take the specification for the DC Gain Accuracy of a SIGLENT SDS1052DL+
For ranges ≤ 100 mV/div, the DC Gain Accuracy is given as
± [3% × (|reading|+|offset|) +1% × |offset| +0.2 * div+2 mV]
If:
Reading = 0.5 V
Offset is 0.1 V
Vertical scale (div) = 100 mV/div = 0.1 V/div,
Then DC Gain is calculated as follows:
± [3% × (|reading|+|offset|) +1% × |offset| +0.2 * div+2 mV] =
± [3% × (|0.5 V|+|0.1 V|) +1% × |0.1 V| +0.2 div * (0.1 V/div) + 0.002 V] =
± [3% × (0.6 V) + 0.0001 V + 0.02 V + 0.002 V] = 0.018 V + 0.0001 V + 0.02 V + 0.002 V = 0.0401 V

Information regarding product compliance is available on the datasheet for each product.

Many SIGLENT instruments feature options that can be added by using an activation code.
To generate the activation code:
– Purchase the option from your favorite SIGLENT office or distributor. A full list of available options are located at the bottom of the specific product web page.
– You will receive an Option Card PDF document from SIGLENT that contains important information for permanent activation of the features. Keep this information handy through the next steps.
– Go to //service.siglenteu.com/easyweb/
-Enter the information from the Option Card in the correct fields of the webpage, and press Submit:

The maximum safe voltage of ext trigger channel is 40 Vpp.
The specification of working voltages are:
Ext : ± 600 mVpp
Ext/5: ±3 Vpp.

When customers purchase oscilloscopes such as SDS1104X-C and SDS1122E+, the sellers often offers bandwidth upgrade services. Some customers hesitate due to concerns about potential impacts on operational smoothness or warranty validity. In fact, upgrades performed through authorized channels will neither compromise the oscilloscopes' performance nor affect warranty coverage...
