The Keysight B1505A Power Device Analyzer / Curve Tracer is the only single-box solution available with the capability to characterize high-power devices from the sub-picoamp level up to 10 kV and 1500 A. These capabilities allow the evaluation of novel new devices such as IGBT and materials such as GaN and SiC. The B1505A supports a variety of modules: high voltage SMU (HVSMU), high current SMU (HCSMU), ultra-high current (UHC) module, ultra-high voltage (UHV) module, and high voltage medium current (HVMC) module. The B1505A also supports high-power SMU (1 A/200 V), medium-power SMU (100 mA/100 V) ,medium-current SMU (1 A/30V pulsed, 100 mA/30V DC), and a multi-frequency capacitance measurement unit (1 kHz – 5 MHz). Its ten-slot modular mainframe allows you to configure the B1505A to suit your measurement needs.

It can also perform fully automated capacitance measurements such as Ciss, Coss, and Crss at high voltage biases (up to 3000 V), gate charge, another important parameter for the high frequency switching converter era, can be evaluated easily. Automatic thermal characterization from -50 ℃ to +250 ℃ is also supported.

The B1505A software environment is based on Microsoft® Windows® 10 operating system and allows users to check device characteristics and detect device faults with the convenience of a curve tracer. Just like a conventional curve tracer, the B1505A supports rotary knob control variable-sweep capabilities. This allows real-time evaluation of parameters such as breakdown voltage. Also supported is “Oscilloscope View” which visually assists the operator in optimizing voltage and current being applied to the device. The measurement setup information and data are automatically stored on the B1505A's built-in hard disk drive. They may also be copied to USB memory sticks and other portable storage devices. Measurement data may be easily copied into engineering reports with the device measurement summary.

A robust test fixture solution is important to ensure operator safety, (due to the generated high voltage and current) as well as to support the wide variety of power device package types. A previous conventional curve tracer limitation was that some power devices could not be evaluated due to their size and it was sometimes necessary to jury-rig an adapter in order to test the device. However, the B1505A's test fixture can accept a wide variety of devices, such as power MOSFETs, diodes, IGBTs etc. regardless of their size or shape. This is achieved via a large test fixture adapter with customizable test fixture modules. In addition, the test fixture's built-in interlock mechanism ensures that high voltages and currents can be safely applied to the test devices.

Keysight can provide a conversion kit that allows existing B1500A users to convert their B1500A mainframe to a B1505A mainframe. This allows current B1500A users to expand the voltage and current measurement capabilities of their existing instrument at a lower cost.
