Measurement Environments
It is important to prevent the device under test (DUT) from light, noise, vibration, and
temperature change to perform measurement, especially sensitive measurement such as
low current measurement and low resistance measurement. Before starting measurement:
Light and Noise
To prevent the DUT from light and noise, attach the light shielding panel (E3120-00211) to
the probe card interface (Agilent B2220A).
Temperature and Humidity
The measurement accuracy is specified at the following temperature and humidity.
Temperature: 23 °C ± 5 °C (73 °F ± 9 °F)
Humidity: ≤ 60% RH
Use air conditioner to keep the temperature constant. Then, prevent the instruments from
direct air flow. The air flow can cool down the instruments. And it will cause the
measurement error.
The following additional conditions should be satisfied for measuring low-current and
low-voltage.
Temperature change: Within ± 1 °C after the calibration
Temperature change period: ≥ 10 minutes
Humidity: ≤ 50%
Floor Vibration
The following vibration conditions should be satisfied for measuring low-current and
low-voltage. Keep away vibrator such as air pump and motor.
Floor vibration: ≤ 1 mG
Floor vibration transmission frequency: ≥ 10 Hz
Also, prevent the instruments and measurement cables from vibration. To do so, stabilize
the instrument rack or table that the instruments are placed, and stabilize the measurement
cables by using tape.
Air Cleanliness
The Agilent 41000 must be located in an area where the air purity meets or exceeds class
100,000 standards. Also, to ensure trouble-free disk and disk drive operation, system
controller peripherals should be located in an environment of similar air purity.
The following air cleanliness condition should be satisfied for measuring low-current and
low-voltage.
Air cleanliness: < class 10,000
