BNC-to-Probe Tip Adapter
The BNC-to-probe tip adapter, Tektronix part number 067-1734-xx, provides connections for signal sources and probe test
points. (See Figure 8.) The adapter breaks out the signal input on the BNC connector to pairs of square pins, one each for
common-mode and differential-mode connections.
1. BNC connector for input signals
2. Differential Mode (DM) square-pin pair
3. Common Mode (CM) square-pin pair (with ground pin)

Probe Calibration Fixture (Optional)
The Probe Calibration Fixture, Tektronix part number 067-0419-xx, prov
ides a means to check the rise time specification of
the probe at the 42 V range (÷ 50) (See Figure 9.) This check is not required to complete the performance verification of the
probe, but is provided for users who want to check the probe rise time at the higher voltage range.
1. SMA connectors for input/output signals and terminations
2. Common Mode (CM) test points
3. Differential Mode (DM) test points
