It is also possible to enter the value in Direct mode. Changing to Direct mode is per-
formed by pressing the ENTER key or with a rotary
‑
knob click; the color of the selec-
tion frame then changes to magenta.
A digit can now be entered using the keypad on the front panel; the digit at the cursor
position is replaced.
In Direct mode, every setting change is immediately passed on to the hardware and
executed. Direct mode can be exited using the ENTER function or the ESC key.
Entering/Changing the Unit of a Value
The unit of a numeric value is displayed next to the entry field.
When the value is entered, all units available for the respective function are offered on
the softkey bar (on more than one level where necessary). The entry can be completed
by selecting the unit using a softkey.
This is done differently depending on the selected mode:
●
In Edit mode, the newly entered numeric value is adopted and set together with the
selected unit.
●
In Direct mode, the physical value (number with the previously selected unit) is
converted to the newly selected unit and adopted as the new numeric value.
Information on Using Reference Values
The audio analyzer allows reference values to be set in various places. These refer-
ence values are used as a basis for settings for other parameters.
The example below explains these interdependencies:
A reference voltage ("Ref Voltage") can be set in the "Generator Config" panel. The
actual output voltage is set in the "Generator Function" panel where the unit is dBr, i.e.
it is possible to enter the output voltage in dB relative to this reference value.
Entering Alphanumeric Values
When the focus is moved to a text entry field, the system enters Edit mode, which is
indicated by a green selection frame.
