Ballantine 6127B

Programmable 1Ghz

Oscilloscope Calibrator

This calibrator provides a wide range of functions allowing the callibration of scopes up to 1Ghz.   Although this unit provides many cal functions by itself.  Many options require specific heads not included.  Since this is a current product, these heads and operating manuals are easily obtained from Ballantine.

This unit is in good electrical and mechanical condition.  Although it does have a few scrapes and scratches on the case and a small crack in the front panel membrane which can be seen in the photos.

 

Product Summary

The BLI 6127B is an accurate and simple way to calibrate a wide variety of oscilloscopes from low frequency units to instruments bandwidths over 1 GHz. The 6127B provides a variety of signals of precise voltage, current, timing and waveshape. The 6127B can be operated manually or automatically using the IEEE-488 interface and Ballantines automated software SCOPE-CAL™. Time saving controlls include computation of percent deviation, repeat step increment, self checking and warning of invalid entries.
