Performance Verification
Performance verification ensures that the instrument performs within the specifications stated in the
data sheet. Some specifications are included in this document and were accurate at the time of
publication, but the latest data sheet from the Keysight website should be referred to see if there are any
changes since this document was published.
Recommended test equipment
The test equipments recommended for the performance verification and adjustment procedures are
listed below. If the exact instrument is not available, use the accuracy requirements shown to select
substitute calibration standards.

current
300 Ω (E36102A) 1/8 W minimum
2.5 kΩ (E36103A) 1/8 W minimum
9 kΩ (E36104A) 1/8 W minimum
20 kΩ (E36105A) 1/8 W minimum

Test considerations
– Ensure that the calibration ambient temperature is stable and between 20 °C and 30 °C.
– Ensure ambient relative humidity is less than 80%.
– Allow a 1-hour warm-up period before verification or calibration.
– Keep cables as short as possible, consistent with the impedance requirements.
