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.

Key Specifications

Frequency Range 1 − 12.4 GHz (useable 0.7 − 15.7 GHz)*
Dial Frequency Accuracy 10 MHz ±3%**
Video Bandwidth 1 kHz, 100 kHz, 3 MHz
Frequency Response ±2 dB typical, ±4 dB maximum
Calibrated Dispersion 0 − 11.4 GHz (useable 0 - 15.0 GHz)
Dispersion Resettability 10 MHz
Dispersion Dial Accuracy 10 MHz or ±0.5% whichever is greater
Preselection 3 Resonator YIG filter, nominal 3 dB bandwidth 15 MHz, straight thru leakage >60 dB down, tracking spurious typically >45 dB down***
Resolution 15 MHz typ.
Image Rejection Generates no image signals
Intermod Rejection Intermod signals are reduced by the preselector selectivity over conventional microwave diode response
Sensitivity −45 dBm min. (1 kHz bandwidth)
Max. Input Power +20 dBm
Limiting Level 0.7 − 1.0 GHz -20 dBm typ., 1.0 − 1.2 GHz >+5 dBm, 1.2 − 15.7 GHz >+10 dBm (all at 2 dB compression)
Log Accuracy ±1 dB typ. (<1 mW input)
Variable Vertical Log Scale (dB/cm) Variable and calibratable with internal calibrate signal over the range of 2 dB/cm to 20 dB/cm
Log Video output 0.02 Volts/dB typ.
Sweep Rate 1, 10, 30 Hz
* 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.
