In some extreme hardware errors, the oscilloscope may become unresponsive or “hang” during the boot sequence.
Oscilloscope Hardware Reset
If your oscilloscope is frozen, will not boot, or appears to be unresponsive, you can attempt a hardware reset by following these instructions:
1. Disconnect all USB, LAN, and input cables. Leave the power cord connected.
2. Power cycle the instrument by pressing the power button.
3. Immediately begin pressing the MATH button repeatedly at a rate of 2 to 3 times a second while the instrument boots up.
4. If the instrument does not boot up properly, retry steps 2 through 4.
NOTE: If you continue to have problems, contact your nearest SIGLENT office for service.
