Features

●Enriched Basic Performance The SG-7200 covers a wide band from 100 kHz to 2 GHz (100 kHz to 1.3 GHz with the SG-7130) and its output level can be varied between -133 and 13 dBm with a high resolution in 0.1 dB steps. The available modulation includes FM, AM, AM/FM,and FM/FM simultaneous modulation as well as DC-FM modulation, which can provide frequency accuracy with an even higher stability. In addition, up to 100 front panel setting conditions including frequencies, output levels and modulation methods can be stored and recalled.  These features make the SG-7000 series a production measuring tool for the communications field, providing enriched basic performance together with high cost efficiency. ●Excellent Operability Features for eliminating operation mistakes and improving the ease of use include; 1) independent control of the frequency output levels using two rotary knobs; 2) key layout for minimizing operation mistakes adopted for frequently-used keys such as the RF on/OFF, FM/AM modulation on/OFF, memory and UP/DOWN keys; 3) direct selection of FM, AM, DC-FM, FM-FM (FM 2-tone) modulation, and so on. ●Highly Stable DC-FM Modulation The DC-FM modulation featuring a high carrier frequency stability of  ±(Reference oscillation ±250 Hz) at <10 kHz deviation is of optimum performance for the pager (because the DC-FM modulation used with the pager should have a high carrier stability). ●100-Step Sequence Memory The sequence memory can be divided into 10 groups and copied to an instrument of the same model. As the GP-IB and remote control connectors are provided as standard, the SG-7000 series can be accommodated in an automated measuring system for use in production automation. ●SPECIFICATIONS SPECIFICATIONS　 Model SG-7130 SG-7200 Frequency　 Range 100kHz to 1.3GHz 100kHz to 2GHz Resolution 10Hz (fc≤1.02GHz) 20Hz (fc>1.02GHz fc: carrier frequency) Accuracy Same as reference oscillator Display 9 digits Switching speed 50ms (standard)?
