1. Connect the calibrator test head to channel 0 of the PXIe-5164.
2. Configure the PXIe-5164 with the following settings:
•
Input impedance: the Input Impedance value from the DC Accuracy Verification
table
• Maximum input frequency: (1 MΩ) 300 MHz, (50 Ω) 400 MHz
• Vertical offset: the Vertical Offset value from the DC Accuracy Verification table
• Vertical range: the Vertical Range value from the DC Accuracy Verification table

Measurement uncertainty based on Fluke 9500B with Fluke 9530 test head specifications that
apply at T
cal
± 5 °C, where Factory T
cal
= 23 °C. Uncertainty of the 9500B includes long-term
stability of 1 year, temperature coefficient, linearity, load, and line regulation and traceability of
factory and National Calibration Standard.
