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 controls include computation of percent deviation, repeat step increment, self checking and warning of invalid entries.
Ballantine has over 300 procedures for scopes on the market.
Maximum adaptability. Checks any scope from general purpose to advanced 1 GHz units.
Cuts calibration time and cost. Halves test time. Speeds throughput to 5 times when programmed.
