1. OUTLINE and FEATURES
The SG-5110 IsanFM-STEREO, FM-AM standard signal generator that covers the
frequency band from 100kHz to110MHz.The output level canbesetinIdB
steps from -20dB# to lOOdB/i.
Al1 set values are easily input by using numerickeys orthe rotary encoder.
The set contents canbe memorized inupto100 addresses.
Control is alsopossible via the RT-100 remote controller(optional) and GP-IB
(factory opt ion)allowing the unit tobe used effectively for bothdesign
andmanufacturingpurposes.
_ Covers the frequencyrangefrom 100kHz to110MHzina superb stable and
accurate way.
Superb settingresolution of 100Hz upto 34. 9999MHzand1 kHzinthe range
above 35MHz.
~_ Contents of frequency,modulat ion, output level sett ings canbe stored
in upto100 addressesmakingiteasy to recal1 the sett ings when required.
~> AF functionallows one-touch deviation measuring.
Setting is faci1itated by either direct settingusing numerickeys orby
normal settingusingcursor and rotary encoder.
