1 Only one of these two probes should be used in a DPT test. The N2819A Differential Probe is used when measuring Gate Current and Gate
Charge. The standard N2873A probe is used with the Clamp Test Module to measure V
2 Use the 0.56 N-m (5 lb-in) 5/16 in. SMA Break-over torque wrench (provided with the PD1500A system) to tighten the SMA cable connector
to the PD1000-60002 Protection Probe. Failure to do so might cause extensive ringing in the DPT measurements. See appendix for details.
