Supply Controls - Promax GF-941 Manual De Instrucciones

If SWP sweep function is selected, this function becomes inoperative when all three
selectors are on rest position, main generator output frequency corresponds to the
lowest sweep frequency when sweep is driven again. This frequency may be
changed through control [8].
[16] Frequency control
Within the range selected by control [15], this control permits frequency supplied by
the auxiliary generator to be selected steadily.
[17] Function and sweep selector
In the same way that the main generator, signal supplied by the auxiliary generator
can be sine, triangular or square. It is picked through this selector. Selector SW
allows to activate the frequency sweep (SWP).
On the main generator SWP function, this selector is inoperative and supplies a
sawtooth signal permanently.
When the four selectors are on rest position, the selected function will be the signal
externally entered into connector [20].
[18] Symmetry control
On 'CAL' counterclockwise end position, the auxiliary generator output signal is
symmetric excepted on SWP function, in which it supplies a sawtooth signal with a
90% symmetry.
On the remainder of its path, the output signal symmetry is variable steadily. In case
of SWP function, the sweep return time varies.
[19] Auxiliary input/output connector
On internal function mode, fitting with some pressed function key, the auxiliary
generator will supply a signal through this output, that fits with the own generated
signal.
On external function mode, this connector is used as a external signal input, the three
function selectors being on rest position.
Maximum input voltage level: ± 10 V
