What to do if I get ERROR 628, DAC over range on my Agilent Technologies Inverter?
- BBrittney RossJul 26, 2025
The 'ERROR 628, DAC over range' on your Agilent Technologies Inverter can occur due to a couple of reasons. One reason is that the signal's amplitude is exceeding the DAC input range, in which case you should scale or reduce the DAC input values. Another reason, specifically on the Agilent MXG, is downloading an encrypted file (.SECUREWAVE) from a PC or USB with an incorrect suffix. If this is the case, use the Use as or Copy File to Instrument softkey menus to correctly download the encrypted file to the instrument.
