| Reference- level offsets are used when gain or loss | |
| occurs between a device under test and the | |
| analyzer input. Thus, the signal level measured by | |
| the analyzer may be referred to as the level at the | |
| input of an external amplitude conversion device. | |
| When an amplitude offset is entered, its value | |
| appears in the lower left corner of the display. | |
