Figure 7. Alias Exposure Zone Checker results. The desired signal is at 150 MHz and an out-of- band signal is at –35 dBc and 642 MHz. The unwanted signal in the second alias zone is 5 dB above the –40 dBc threshold line.
When no alias zones exist because the current sampling mode is alias free, no orange zone boxes will appear. In addition, the message No Alias Zones Detected! Restore Initial Settings? will appear (see Figure 8).
