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.
2. 클립을 신호의 기준 접지에 연결하면 오실로스코프와 측정 신호 간 기준 접지 전위 차이로 인한 파형 왜곡을 효과적으로 감소시킬 수 있습니다.
3. SIGLENT SDS1000 시리즈는 밀리볼트 수준 신호 측정이 가능하며, 최저 2mV/div 범위에서 대역폭 제한 기능이 자동 활성화되어 고주파 잡음을 효과적으로 제거합니다.
