Metrix GX1010 Notice De Fonctionnement page 105

3. With 100kHz squarewave selected, increasing symmetry beyond 80% will cause the
message 'SYMMETRY TOO WIDE FOR FUNC/FREQ' to be displayed. The setting will
be accepted but the actual symmetry will be limited to 80% as shown in the bracketed
field beside the setting. If this out-of-specification setting is changed by reducing the
frequency below 30kHz or by changing the waveform then the warning 'SYMMETRY
CHANGED BY FUNC/FREQ' is displayed.
ERROR messages are shown when an illegal setting is attempted, most generally a
number outside the range of values permitted. In this case the entry is rejected and the
parameter setting is left unchanged. Examples are:
1. Entering a frequency of 100 MHz. The error message 'FREQUENCY/PERIOD VAL OUT
OF RANGE' is shown.
2. Entering an EMF of 25V pk-pk. The error message 'MAX OUTPUT LEVEL EXCEEDED'
is shown.
3. Entering a DC offset of 20V. The error message 'MAX DC OFFSET EXCEEDED' is
shown.
The messages are shown on the display for approximately two seconds. The last two
messages can be viewed again by pressing the blue EDIT key followed by MSG (the 0
number key). Each message has a number and the full list appears in Appendix 1, together
with some further explanation where the message is not entirely self-explanatory.
The default set-up is for all warning and error messages to be displayed and for a beep to
sound with each message. This set-up can be changed on the ERRor menu, accessed by
pressing the blue EDIT key followed by ERRor key (the 2 number key). The ERRor menu is
shown below:
The flashing cursor can be moved through each of the four editable fields in turn using the
FIELD keys. The field can then be toggled between ON and OFF, using the DIGIT keys or
rotary control, to create the desired setting. If the new setting is required for future use it
should be saved by changing the POWER UP= setting on the SYStem menu to POWER
UP=POWER DOWN, see System Menu section.
