1. OUTLINE and FEATURES
The SG-5260 isan FM-AM standardsignal generator thatcoversthe frequency
band from 10kHz to 260MHz. The output level canbesetin0.1dBsteps from
-20dB# to 132dB//.
All setvaluesare easily inputbyusing numeric keys ortherotary encoder.
Thesetcontentscanbe memorized inupto100addresses.
Controlisalsopossibleviathe GP-IB (factory option)allowingtheunitto
be used effectively for both designand manufacturing purposes.
• Covers the frequency range from 10kHz to 260MHz ina superb stableand
accurateway.
• Superb sett ing resolut ionof 100Hz.
• Content s offrequency, modulat ion, output level sett ingscanbestored
in upto100addresses making it easy torecal1the sett ings when required.
•AFfunctional lows one-touch deviation measuring.
•Settingis faci1itated by ei ther direct setting using numeric keys orby
normal setting usingcursorandrotary encoder.
•Selectable modulat ion signal. Select between internal osci 1 lator or
externally input signal.
• Operat ional ease secured byfunctiontopreset f requently used output
levels and second functionselectable,presetstandard modulat ion.
•Providedtheoptional RT-101 remote contro1leris connected, control
from a distance becomes possible.
• Designed for automat ionof measuring via GP-IB function (factory opt ion).
