EIP 548A Microwave Frequency Counter with Options 06 & 08 10Hz - 26.5 GHz

Description

This is a high quality microwave frequency counter, with a frequency range of 10Hz to 26.5GHz.
Includes a print-out of the "Operations" chapter from the manual and an expired calibration certificate (from 2005).
This unit w
as used, until recently, in a professional environment. It was last calibrated in 2006 (partial calibration by a lab that was equipped to only calibrate up to 20GHz).  Included is the calibration certificate from its 2005 calibration.
It is equipped with option 06 (extended frequency range) and option 08 (GPIB).  The extended frequency option requires a separate cable and sensor head, neither of which is included.
I have included videos demonstrating its functions (to the best of my ability).  I only have a 1000MHz signal generator, with a free-running oscillator, so the frequency range and accuracy of this unit is not fully represented.
