Power Supply Current Measure IP is an algorithm IP to measure power supply current.
By using Power Supply Current Measure IP, the following electrical characteristics for target devices can be measured and evaluated easily.
- Static power supply current
- Dynamic power supply current
In addition, by using Multipoint Measurement Plugin, the following electrical characteristics for target devices can be measured and evaluated easily.
- IDDQ test
- Maximum power supply current
- Minimum power supply current
- average power supply current
- Variability for power supply current (3σ）
This IP has the following functions.
Can measure the power supply current for the pin connected to the following channels.
- Power Supply
- ATES UTILITY Power Supply 6V 4A
It is a channel of UTILITY BOX manufactured by ATE Service Corporation. It can be used when connecting to UTILITY BOX.
Can measure the power supply current for the specific operating state by executing pattern. For the details, refer to Pattern Execution and Measurement.
Can measure by opening the pin out relay of the I/O pin. It is possible to reduce the influence of the leakage current of the measurement system. For the details, refer to Change Operating State for I/O pins.
Can measure by applying VIH/VIL voltage to the device pins. For the details, refer to Change Operating State for I/O pins.
Can measure by changing the measurement range. For the details, refer to Change Measurement Range for Power Supply.
Measurement values and judgement results can be stored to variables by interpose processing. For the details, refer to Interpose Processing.
Can judge the pattern execution result. For the details, refer to Judgement for Pattern Execution Results.
Execute the finalization pattern. For the details, refer to Execute Finalization Pattern.
Apply the arbitrary waveform synchronized with pattern by Arbitrary Waveform Applying Plugin.
Supply the power from external power supply instruments controlled by GPIB by External Power Supply Control Plugin.
Measure by multiple pattern execution condition in one test item (in the rest of this document referred to as “Multipoint Measurement Function”) by Multipoint Measurement Plugin. In addition, can judge statistical values at each measurement point. For the details, refer to Multipoint Measurement Plugin Reference Manual.
Execute the batch file at specified timing of the measurement sequence to algorithm IPs by Batch File Execution Plugin.
