Frequently Asked Questions - SDS1204X Siglent
How to calibrate the SDS1204X oscilloscope?
Use the built-in calibration output (1 kHz, 1 V peak-to-peak) on the front panel. Connect a probe to channel 1 and adjust the vertical scale and timebase to display a stable square wave. If necessary, adjust the probe compensation.
What is the maximum allowed input voltage?
The maximum direct input voltage (without probe) is 400 V peak (CAT I). With a 10x probe, it can reach 4000 V peak depending on the probe used.
How to update the firmware?
Download the latest firmware from the official Siglent website. Copy it to a USB drive formatted as FAT32, insert it into the oscilloscope, then go to Utility > Firmware Update menu.
Can I use probes from other brands?
Yes, as long as the probe is compatible with an input impedance of 1 MΩ//15 pF and has a standard BNC connector. Check the maximum voltage and bandwidth of the probe.
How to perform an automatic frequency measurement?
Press the Measure key, select Source to choose the channel, then select Frequency from the parameters. The value is displayed in real time.
What to do if the screen does not turn on?
Check the power cable and the mains outlet. Ensure the power switch is pressed. If the screen remains off, contact after-sales service.
How to save a waveform?
Press the Save/Recall key, choose Waveform as the type, then select the storage location (internal or USB). Give a name and confirm.
Triggering is not working correctly, what to check?
Check the trigger level, slope type (rising/falling), and coupling (AC/DC). Ensure the trigger source matches the active channel.
How to use serial decoding (I2C)?
In the Decode menu, select the I2C protocol, assign the channels for SDA and SCL, set the voltage thresholds. The oscilloscope will automatically decode the frames.
Where to find the serial number?
The serial number is on a label at the back of the device, near the power connector. It is also accessible via the Utility > System Info menu.
