When running SPC (signal path compensation) on my oscilloscope, I get the message that SPC failed.  What does failing SPC indicate?

When an oscilloscope says SPC failed, 99.9 percent of the time it is a hardware failure that will need repair.  A few things you can do before sending in for repair:

Make sure all inputs (probes and cables) are removed from all the channel inputs.

Make sure the oscilloscope has been warmed up (typically 20 minutes)

Run the oscilloscopes “Default Setup”

If not running the latest oscilloscope firmware, download and install the latest version from Tek.com.

If the oscilloscope still presents a SPC failure, the unit will need to come in for a repair
