Auto and Manual Parameter Coupling (6GR)
Almost every configurable value in the 6GR measurement is auto-coupled: you can either set it manually, or leave it on and let the measurement supply the value. The choice is made per parameter — there is no global auto/manual mode, though Auto Detection can supersede these parameters for whole channels (see Relationship to Auto Detection below).
What supplies depends on the parameter. Some auto values are derived from the rest of the signal configuration and change whenever something upstream changes — for example, a timing offset that tracks a chosen slot boundary, or a table selection implied by a bandwidth and subcarrier-spacing choice. Other parameters have no derived value to compute, and simply means the parameter keeps its default until you set it yourself.
The Visual Convention
Auto-coupled rows appear throughout the , , , and tabs. Each one is a value control (text box, combo box, or toggle) that shows the value currently in effect, whether that value came from Auto or from you:
- Auto mode — the value control shows what the measurement supplied. You are not required to know or set this value. Nothing appears beside the value control.
- Manual mode
— you have entered or selected a value, and it stays exactly what you set, regardless of what else changes. A lock button appears beside the value control to mark the parameter as overridden; click it to return the parameter to .
The lock button
is the only indicator of the mode: a row showing the button is manual, and a row with no button beside its value is on Auto.
Auto-coupled value controls stay editable in both modes, and there is no separate control for turning Auto off:
- To override a parameter, simply set the value — type a number, pick a combo box item, or flip a toggle. That switches the parameter to manual on its own, and the lock button appears.
- To return it to Auto, click the lock button. The parameter's automatic value is restored, the manual value is discarded, and the button disappears again because the parameter is no longer overridden.
A value control that is dimmed is not indicating Auto. It means that parameter does not currently apply, because of another setting that gates it.
Why This Exists
Auto means you do not have to compute or re-enter a value by hand every time something upstream changes, and you do not have to know a value at all in order to get a measurement. But any of these values can also be a deliberate test condition (e.g., deliberately mis-set to see how the measurement behaves), so every auto-coupled parameter remains directly settable.
Relationship to Auto Detection
Auto Detection is a separate mechanism from auto and manual parameter coupling. Auto coupling supplies a parameter's value from the rest of your configuration; auto detection determines the signal's structure from the acquired signal itself. Auto coupling is chosen per parameter; auto detection is chosen per channel type (, , ).
While a channel's detection is enabled, the measurement demodulates the allocations the detector found, so the values you configured for that channel are not the ones in use — whether those values are on or manually set. A lock button on such a parameter does not mean the measurement is using that value.
Copy To Setup is how detected values become configuration. It writes each detected parameter into the carrier definition and clears that parameter's flag, so copied values appear as manual settings with their lock buttons shown. Parameters the detector could not determine are left untouched, still on .
Relationship to Preset to Standard and Signal Definition Import
returns every auto-coupled parameter to Auto, in addition to resetting the underlying configuration. If you have been experimenting with manual overrides and want a clean baseline again — including undoing the overrides themselves, not just the values — does both at once.
performs the same full preset internally before applying the file, so every parameter starts the import on Auto. Any parameter the file does not specify stays that way. Parameters the file does specify are set to the imported value, and become manual only where that value differs from what Auto was already producing — a parameter whose imported value matches its automatic value is left on Auto rather than being needlessly locked. The normal result after an import is therefore a mix: most parameters Auto, and a smaller set manual, marking what the file genuinely changed. The import result's detail area lists the parameters left on Auto for this reason. See Preset to Standard and Signal Definition Import/Export.
