    What to do if the SIGLENT Test Equipment screen remains dark after power on?
    • E
      Edwin HolderAug 5, 2025
      If the screen of your SIGLENT Test Equipment stays dark after you turn it on: * Ensure the power cord is properly connected. * Inspect the fuse for burnout. If a replacement is needed, contact SIGLENT to return the instrument for repair by authorized personnel. * Restart the instrument after checking the connections and fuse. * If the issue persists, further troubleshooting or contacting SIGLENT may be required.

    Why is the waveform displaying on my SIGLENT Test Equipment not stable?
    • M
      martinmichaelAug 9, 2025
      If the waveform display on your SIGLENT Test Equipment is unstable, consider the following: * Check the trigger source to ensure the “Source” in the “TRIG” menu matches the actual operating channel. * Verify the waveform itself, ensuring the time base is appropriate for the input signal's frequency. * Confirm the trigger type is correct; “Edge” is suitable for general signals, while “Video” is best for video signals. * Adjust the trigger holdoff setting.

    How to fix no waveform displaying on SIGLENT Test Equipment after sampling the signal?
    • B
      bryantarthurAug 13, 2025
      If you're not seeing a waveform on your SIGLENT Test Equipment after sampling a signal: * Ensure the signal cord is correctly connected to the BNC connector. * Verify the Intensity knob on the front panel is properly adjusted. * Confirm the probe is correctly connected to the device under test. * Check if the device under test is generating a signal. You can use the probe compensation signal to test the channel. * Try resampling the signal.

    Why is the voltage amplitude measured on my SIGLENT Test Equipment inaccurate?
    • J
      Janice DavisAug 17, 2025
      If the voltage amplitude measured by your SIGLENT Test Equipment is inaccurate: * Verify that the attenuation coefficient of the channel matches the probe's attenuation ratio. * Check if the BW Limit is enabled under the CH1/CH2 menu. If it's on, it can cause the amplitude to appear lower than the actual value.

    What to do if there is no display after pressing RUN/STOP on SIGLENT Test Equipment?
    • K
      Krystal LongAug 22, 2025
      If nothing displays after pressing RUN/STOP on your SIGLENT Test Equipment: * Check if the trigger Mode is set to “Normal” or “Single” and if the trigger level is outside the waveform range. Adjust the trigger level to the middle or change the trigger Mode to “Auto”. * Alternatively, press AUTO to automatically adjust these settings.

    Why my SIGLENT Test Equipment does not recognize the U disk?
    • M
      Michael GutierrezAug 27, 2025
      If your SIGLENT Test Equipment isn't recognizing the U disk: * Confirm the U disk works normally. * Check if the USB Device interface is functioning correctly. * Ensure you're using a flash-type U disk, as hardware types are not supported. * Make sure the U disk's capacity isn't too large; a capacity no larger than 4 GB is recommended. * Restart the instrument and re-insert the U disk. * If problems persist, contact SIGLENT.

    How to resolve ladder-like waveform display on SIGLENT Test Equipment?
    • J
      juliebakerAug 30, 2025
      If the waveform on your SIGLENT Test Equipment looks like a ladder: * Increase the horizontal time base to improve the horizontal resolution for better waveform display. * If the “Type” in the “DISPLAY” menu is set to “Vectors”, switch it to “Dots”.
