Please note that in ISOFREQUENCY systems, the
reference 19kHz frequency is kept in phase and on
frequency by the external or internal GPS systems. In
normal equipments, frequency is compliant with
applicable standard (19 kHz +/-2Hz).
[delay]
In this submenu, you may use the knob to set the delay
between system inputs and outputs.
•
[BACK] Push the encoder when this item is blinking
to cancel selection mode and go back to scrolling
through display screens by turning the knob.
•
D [uS.]:[0000,0] This field lets you set delay.Setting
range may be adjusted from 0 to 9931.8 uSec., in
increments of approx. 5.4 uSec.
•
D [nS.]:[0000,0] This field lets you set delay end.
Setting range may be adjusted from 0 to 6307.8 nSec.,
in increments of approx. 49.6 nSec.
Set delay is added to system software processing fixed
delay. At each start-up, the delay between audio input
and MPX output is constant.
In ISOFREQUENCY operation, delay affects the whole
MPX packet and thus allows audio and pilot phasing of
equipments (if connected to GPS).
NOTE: This is the only window where set values are not
updated until selection is cancelled, i.e. not in real time.
This is because an update creates a micro-interrupt in
the process (which may or may not be apparent), making
it impossible to set a delay when the system is subject to
repeated interrupts. When looking to set optimal delay,
push the knob after each adjustment to check outcome
and then push the knob again to try a new setting.
[coder]
If the encoder is pushed when in this submenu, field [BACK] begins
to blink and you will be able to move the cursor from field to field by
turning the knob in the desired direction.
Push the encoder again when a field is selected to confirm that you
wish to edit the current selection.
