Nine overlapping ranges cover the frequency band from 250 kHz to 250 MHz, with an additional range reserved for a 50 kHz reference frequency. | |||
It was primarily intended to be used as an oscilloscope calibration device for measuring bandwidths up to 250 MHz. Unlike later instruments like the [[SG504]], it does not use a leveling head but was designed and calibrated with high quality coaxial cable (P/N [[012-0482-00]]) to operate as a closely matched system when terminated into a 50 Ω load. | It was primarily intended to be used as an oscilloscope calibration device for measuring bandwidths up to 250 MHz.
