The '''EIP 101A''' is a receiver-type Spectrum Analyzer plug-in, designed to work in all Tektronix oscilloscope mainframes which accept letter-type plug-ins. 
Used in the 201A power supply unit, it works together with all analog oscilloscopes. 
It covers the frequency range of 0.7 - 15 GHz in one single band and comprises a three-resonator YIG preselector.

{{EndSpecs}}
:<sup>*</sup> Usable frequency coverage is limited by the center frequency dial indicator with the unit set on a center frequency of 12 GHz and dispersion set for 15 GHz, most units will display signals as high as 18 GHz.
:<sup>**</sup> If setting is always approached from 700 MHz, if not, add 5 - 15 MHz for hysteresis. 
:<sup>***</sup>Tracking spurious is a second pass band response, always located a fixed number of MHz (approximately 200 MHz) above the normal preselector response.
