Will a bandwidth upgrade affect oscilloscope user experience?
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… Click to view details.

Measuring small signal waveform is disturbed too much.
1、鼎阳的SDS1000系列最小可以测到毫伏级别信号，并在最低的2mV/div档位自动开启带宽限制功能，有效滤除高频杂波。 2、将夹子接到信号的参考地上，这样可以有效的减少因为示波器与测量信号因为参考地电位差异导致的波形显示失真。 3、鼎阳的SDS1000系列最小可以测到毫伏级别信号，并在最低的2mV/div档位自动开启带宽限制功能，有效滤除高频杂波。

Waveform appears but is not stable
3.1 Check that the trigger source channel is consistent with the waveform being viewed3.2 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 stable3.4 Adjust time base, rule out false-wave interference (such as alias displayed waveforms)

The oscilloscope does not turn on
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…

What does “div” mean in the specifications?
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 VOffset…
