If You Have a Problem
When You Perform Measurement
Noise Affects the Measured Values
When you measure low current of a DUT, the measured values may not be stable.
To solve this problem:
• Set the power line frequency correctly. The value affects the integration time. So
the wrong value causes the measurement error by the power line noise. You can
set the power line frequency by using the Configuration window of the
EasyEXPERT.
• Use guarding to reduce the leakage current between your prober and the B1500.
Note that long wires cause oscillation because of their large inductance.
• If some high-power electric machines are operating around the B1500, turn off
the machines, then perform the measurements. The machines affect the power
line waveform.
• Shut the lid of test fixture or shield box to prevent effects of light.
• If these are vibrations due to nearby machines or due to air flow, put cushioning
material under prober, cable, and the B1500; install stabilizer on the prober; and
make the cables stable by taping.
• Wait several minutes after connecting cables or moving probe needles. Because
these operations cause electromotive force.
• If you use only Force terminal and triaxial cables, connect an open cap to Sense
terminal.
• Keep constant temperature in the room when you use the B1500. Shift of 1 C
may shift the measurement values. Temperature change causes the following.
• Offset current in the B1500.
• Thermoelectromotive force in DUT, which causes low current.
• Expansion and contraction of cables, which causes noise.
