Standard Signal Generators SG-5155

---

Outline

The SG-5150 is a programmable FM stereo/FM/AM standard signal generator integrating an RF signal generator with continuous coverage in the range from 100 kHz to 150 MHz & a stereo signal generator. This is the ideal choice for production line quality control and the servicing of products? including not only FM/AM radio and FM stereo tuners? but cordless telephones as well. All operations can be remotely controlled by using the optional remote controller or the GP-IB (factory option)? which also allows improved efficiency in the design and production departments.The SG-5155 is a FM standard signal generator integrating an RF signal generator with continuous coverage in the range from 100 kHz to 150 MHz.

Features

●The RF signal is generated with high precision by a highly stable PLL synthesizer technique. ●The output level can be set in the range from -20dBμ to 100dBμ in 1dBμ steps by a high-accuracy attenuator. ●The STO and RCL keys can be used to store and recall the programmed values. ●The frequency is shown on a 7-digit LED display. It is not only continuously variable but an arbitrary digit can be varied by aligning the cursor. In addition, a ΔF display is provided. ●The stereo modulation has excellent distortion figures, S/N ratios and separation characteristics. A preset key enables the setting of the modulation depth to 30% or 100%  (SG-5150 only). ●The storage and recall of up to 100 front panel setting conditions are possible. By using the optional RT-150 Remote Controller, it is possible to remotely control all operations. ●Compatibility with the GP-IB (factory option) enables automated measurements. ●SPECIFICATIONS SPECIFICATIONS Model SG-5150 SG-5155 Frequency Range 100kHz～150MHz 100kHz to 150MHz Display 7-digit LED display 7-digit LED display  Resolution 100Hz (below 34.999MHz) 1kHz (35MHz and above) 100Hz (below 34.999MHz) 1kHz (35MHz and above)  Δf Direct display  ±0.9999MHz ( below 34.999MHz) ±0.999MHz (35MHz and above) ±0.9999MHz ( below 34.999MHz) ±0.999MHz (35MHz and above)  Accuracy ±5×10-6 ±5×10-6 Output Level range -20dBμ to 100dBμ (open circuit) -20dBμ to 100dBμ (open circuit) Display 3-digit LED display 3-digit LED display Resolution 1dB 0.1dB Level accuracy ±1dB (at 100dBμ) ±1dB (at 100dBμ) Attenuator accuracy ±1dB (0 to 100dBμ) ±2dB (-20dBμ to 0dBμ)  ±1dB (0 to 100dBμ) ±2dB (-20dBμ to 0dBμ) Output impedance 50Ω (VSWR1.2 max.) 50Ω (VSWR1.2 max.)
