SIGLENT 2.6.1 CH1, CH2 Channel Table 2-1 CH1, CH2 function menu 1: Option Setting Introduction DC DC passes both AC and DC components of the input signal. Coupling AC AC blocks the DC component of the input signal and attenuates signals below 10 Hz. GND GND disconnects the input signal. Limits the bandwidth to reduce display On noise; filters the signal to reduce noise and BW limit other unwanted high frequency Off components.
SIGLENT Setting CH1, CH2 Channels Each channel has its own separate Menu. The items are set up separately according to each channel. 1. Choosing Coupling Take the CH1 for example; the tested signal is a sine wave signal with DC deflection: ● Press“CH1”→“Coupling”→“AC”, Set to AC couple mode. It blocks the DC component of the input signal. ● Press“CH1”→“Coupling”→“DC”, Set to DC couple mode. Both DC and AC component could be obstructed. ● Press“CH1”→“Coupling”→“GND”, Set to GROUND mode.
SIGLENT Set BW to 20MHz BW Limit Symbol Picture 2.6-3 3. Adjust Sensitivity Vertical scale adjusting has Coarse and Fine two modes, Vertical sensitivity range is 2mV/div～10V/div scale.

SIGLENT 2.8.6 Trigger Holdoff You can use the Trigger Holdoff function to produce a stable display of complex waveforms. Holdoff is time between when the oscilloscope detects one trigger and when it is ready to detect another. The oscilloscope will not trigger during the holdoff time. For a pulse train, you can adjust the holdoff time so the oscilloscope triggers only on the first pulse in the train. Trigger position Trigger level Holdoff time Picture 2.
SIGLENT 2.9 Acquiring Signals System Showing as the follow picture，the “ACQUIRE” button for Acquiring Signals system is at the menu. Picture 2.9-1 Table 2-28 Option The Function manual of Acquiring Signals: Setting Introduction Use for sampling and accurately display most Sampling of the waveform. Peak Detect the noise and decrease the Acquisition possibility of aliasing. Detect Use to reduce random or uncorrelated noise Average in the signal display.
SIGLENT occur between samples. This can result in aliasing may cause narrow pulses to be missed. In these cases, you should use the Peak Detect mode to acquire data. Picture 2.9-2 Sampling modes ■ Peak Detect: Peak Detect mode capture the maximum and minimum values of a signal Finds highest and lowest record points over many acquisitions. Advantage: In this way, the oscilloscope can acquire and display narrow pulses, which may have otherwise been missed in Sample mode.
SIGLENT ■ Average: The oscilloscope acquires several waveforms, averages them, and displays the resulting waveform. Advantage: You can use this mode to reduce random noise. Picture 2.9-4 Average Mode ■ Equivalent Time Sampling: The equivalent time sampling mode can achieve up to 20 ps of horizontal resolution (equivalent to 50GSa/s). This mode is good for observing repetitive waveforms. ■ Real Time Sampling: The scope has the highest Real-time sampling rate up to 1GSa/s.
SIGLENT When you push the RUN/STOP or SINGLE buttons to start an acquisition, the oscilloscope goes through the following steps: 1）. Acquire enough data to fill the portion of the waveform record to the left of the trigger point. This is also called the pre-trigger. 2）. Continue to acquire data while waiting for the trigger condition to occur. 3）. Detect the trigger condition. 4）. Continue to acquire data until the waveform record is full. 5）. Display the newly-acquired waveform.

SIGLENT 3.2 Troubleshooting 1. After the oscilloscope is powered on，the screen remains dark ，please do as following steps： ⑴ Check the power cable’s connection. ⑵ Ensure the power switch is turned on. ⑶ After the inspections above，restart the oscilloscope. ⑷ If the oscilloscope is still not used after the checking, please connect with Siglent 2.
SIGLENT automatically. 6. After the Acquisition is set to Averages or Display Persistence time is set too long, the waveform refreshes slowly. It is normal in these settings 7. The signal is displayed as ladder like waveform (1)This phenomenon is normal. The time base maybe is too slow .you should turn the horizontal scale knob to increase horizontal resolution to improve the display. (2) Maybe the display Type is set to “Vectors”, You could set it to Dots mode to improve the display.
