La description détaillée de marque:The high performances of generator, along with problem of providing
parameter check of communication receivers of movable service with amplitude
(AM), frequency (the FM) pulsed (them) modulating, including the inspection ìíî-
ãîñèãíàëüíîé selectiveness, permits its use for âíóòðèêà-
íàëüíûõ and âíåêàíàëüíûõ measurements of majority of modern and ïåðñïåêòèâ-
Noy communication facilities.
the low level of amplitude noises make it possible èñïîëüçî
to âàòü the generator as a heterodyne in different measuring circuits,
for example when measured of large weakenings.
the possibility exists of setting of parameter with keyboard ïîìùüþ and
pen of êâàçèïëàâíîé setting of parameter at the front of. The choice íå-
bypassed frequency step significantly improve efficiency
work with device. Keeps in mind more than 10 óñò-õ alternatives of parameters
the generator can work in the composition of computer-based information system and with programme óïðàâëåíè-
