Subsequent to starting the operation system, the
application for the Vector Signal Generator is
loaded in a start-up program. The program start is
initiated automatically and generates a window,
which displays information on the start-up
p
rocedure.
Information on the used software version is
displayed at the bottom of the window.
Note: When the software is started, information on
the instrument configuration and SW
version can be found under:
Menu -> Setup -> Installed Options.
Normal action Error and error cause
During this loading procedure, the FPGAs of the
modules registered in the instrument are
initialized and undergo a functional test. This
loading procedure may take some time
depending on the number of installed options.
If an error occurs, the module concerned must be
changed:
If an error occurs at the very beginning of the
process, the DACIF board is probably defective.
If errors occur at a later point, the board concerned
is specified in the error message.
Keyboard and Rotary Knob Test
• This utility allowes to check proper function of all front panel control elements.
Normal action Error and error cause
Test called with
SETUP - Check Front Panel…
An image of the front panel appears with grey
keys.
When a key is pressed once or the knob is
moved, the field changes to green.
If the key is pressed more than once, the field
changes to red.
Note: Take care with the rotary knob! Turn only
slightly in the specified direction, otherwise
the field changes to red.
All fields are green when all operating elements
including the rotary knob have been actuated
once and red if actuated twice.
If colour changes to red at the first actuation, a
malfunction has occurred (bouncing).
If the colour of the corresponding field remains the
same after actuation, the function is defective.
In both cases:
Change the switching pad and/or rotary knob.
A message is output when all keys have been
pressed:
“All Front Panel Keys were accessed correctly”
Note: No error message is output even if a
number of keys are red. The user himself
must decide whether a malfunction has
occurred.
