Minimum Hold
| Maintains the minimum level for each trace point | |
| of the selected trace, and updates each trace point | |
| if a new minimum level is detected in successive | |
| sweeps. | |
| Changing the vertical scale (Amplitude, Scale Type, Log or | |
N O T E | ||
Line), or pressing PRESET, or turning averaging on (TRACE, | ||

| Average (On)) or switching widow in Zone Span restarts the | |

Key access: [TRACE]
View
Holds and displays the amplitude data of the selected trace. The trace register is not updated as the analyzer sweeps. If a trace is deactivated by pressing Blank, the stored trace data can be retrieved by pressing View.
Key access: [TRACE]
Blank
Stores the amplitude data for the selected trace and removes it from the display. The selected trace register will not be updated as the analyzer sweeps. This function is activated for traces 2, 3 and 4 at power- on and Factory Preset.
Key access: [TRACE]
Detector
Selects a specific detector, or uses the system to pick the appropriate detector for a particular measurement.
When discussing detectors, it is important to understand the concept of a trace “bucket”. For every trace point displayed, there is a finite time during which the data for that point is collected. The analyzer has the ability to look at all of the
