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)

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…

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 is 0.1 VVertical scale…
