La description détaillée de marque:Possessing high sensitivity 10Å-17 of computer engineering, the directive allows to:
- to measure antenna polar diagrams in phase and amplitude;
- to measure the high degree of generators screening and different ðàäèîòå-
õíè÷åñêèõ devices;
- to measure the receiver sensitivity of ñïóòíèêîãî television and ñïóòíè-
êîâûõ communication systems;
- to measure the weakening, the strengthening, the sensibility of assemblies and systems radio-
onoff relation, assemblies of transceiving paths;
the built-in microprocessor provides the mathematical processing
and conclusion of digital information about observed values.
the directive can be used in the composition of automated èçìå-
ðèòåëüíîé system with work through cop..
in the composition of directive set the necessary recruitment êîàêñèàëü-
Noy and waveguide transitions for connecting to national or çàðó-
áåæíûì generators is included.
