1. External Reference not found. Internal reference Locked Successfully
This message is displayed when the instrument has detected an external reference but couldn’t lock to the reference. It automatically switches to the Internal Reference. This could happen if the external reference frequency does not match the specified external reference frequency in the Setup menu.

Notifications
1. RF Over Power
2. ADC over range
a. If Auto Range is On - ADC over range: Decrease input power.
b. If Auto Range is Off - ADC over range: Adjust range or decrease input power.
3. Level Under
a. If Auto Range is On - No signal detected: Increase input power.
b. If Auto Range is Off: Adjust range or increase input power.
4. Out of band saturation
When the software detects that there is too much power outside the current frequency range, this message is displayed. This usually means that the instrument is currently tuned to a frequency with a very low amplitude signal or no signal and there is a strong signal at another frequency outside the current IF bandwidth.
5. Poor Range
a. If Auto Range is On - Weak signal: Increase input power.
b. If Auto Range is Off: Adjust range or increase input power.
6. Lock Failure xx
When there is a lock failure detected from any of the internal LOs, this message is displayed. The xx is usually an error code in hex that can be interpreted by a service center to obtain more information on which LO had the failure.
