If You Have a Problem
When You Perform Measurement
When You Perform Measurement
This section covers the following basic problems that you may encounter when you
making a measurement, and the solutions.
• “Measurement Takes More Time than Specified”
• “Noise Affects the Measured Values”
• “Voltage Measurement Error is Large”
• “SMU Oscillates for High-Frequency Device Measurements”
• “SMU Oscillates for Negative Resistance Measurements”
• “Large Current Causes High Temperature (Thermal Drift)”
• “Measurement Damages the Device under Test”
• “Leaving Connections Damages Devices after Measurement”
• “Unexpected Sampling Measurement Data is Returned”
• “MFCMU Causes Unbalance Condition”
Measurement Takes More Time than Specified
If you set many measurement channels, auto ranging mode, or too long integration
time, measurement takes a longer time.
To solve this problem:
Depending on your measurement requirements, perform following:
• Decreases measurement channels.
• Uses limited auto ranging mode.
• Uses fixed range.
• Decreases averaging samples of the high-speed A/D converter.
• Decreases integration time of the high-resolution A/D converter.
• Disables the ADC zero function.
