FUNCTION
FUNCTION keys:
Selection of one of the 7 available functions.
SHIFT K, or SWEEP, or MODUL or BURST functions activated: selection of
the INTernal or EXTernal command signal.
•
SHIFT K or SWEEP or MODUL or SYNC functions activated: selection of
a specific function mode (see Function list and adjustment paragraph).
•
BURST function and EXTernal source activated: manual triggering of a
set of pulses.
•
calibration: triggers the selected adjustment step.
•
Autotest: triggers the selected test.
•
SWEEP activated with INTernal source: assignment of the wheel to the
desired timing adjustment to carry out a frequency sweep; then, by
pressing several times, selection of the digit on which to apply the
increment
.
•
BURST function active: assignment of the wheel to the adjustment of the
number of pulses or the burst generation period (INT source); then, by
pressing several times, selection of the digit on which to apply the
increment
.
Division or multiplication by 10 of the current frequency value (decade change).
•
Assignment of frequency adjustment to the wheel; then, by pressing
several times, selection of the digit on which to apply the increment
.
•
SWEEP or MODUL FM or FSK activated: same functions with the
FreqSTART and Freq
end
frequencies.
•
SYNC function activated: adjustment of the de-phasing between the two
generators using the wheel.
•
PSK function activated: by pressing several times, adjustment of the
PhaseSTART or Phase
end
using the wheel.
