EIP 101A

Manuals – Specifications – Links – Pictures

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.

^* 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.

^** If setting is always approached from 700 MHz, if not, add 5 - 15 MHz for hysteresis.

^***Tracking spurious is a second pass band response, always located a fixed number of MHz (approximately 200 MHz) above the normal preselector response.
