Verify that the equipment meets the minimum requirements.
Refer to the computer's documentation for troubleshooting and repair.
Check the signal generator for any error messages. If the signal generator returns Error 628, see ”628 Baseband Generator DAC over range” below. Otherwise, refer to the error messages list on the instrument's documentation CD-ROM.

"628 Baseband Generator DAC over range"
Cause: The I/Q Scaling value is set too high.
Solution: I/Q Scaling is preset to 70%. In most cases, this setting provides good dynamic range without overdriving the I and Q DACs. Increasing the I/Q scaling value beyond 70% increases the risk of DAC over-range errors. If an error occurs at the signal generator, reduce the I/Q Scaling value until errors no longer occur.
