Keysight B1500

The Keysight B1500 extension package for Measmatic provides a set of tests and a Python device for the Keysight B1500A semiconductor device parameter analyzer. The tests use the SMU and MFCMU modules of the B1500 for I-V and C-V characterization of two-terminal devices and MOSFETs.

🟢 Included tests#

  • B1500 IV Sweep: Classic I-V sweep with up to ten SMUs: voltage, current and pulse sources, VAR1 primary sweep, VAR2 secondary steps, synchronous VAR1' and constant or common bias. Supports linear and logarithmic single and double sweeps with configurable measurement, ADC, timing and compliance settings.
  • B1500 IV Sweep 2 pole: Two-terminal voltage sweep. Terminal 1 supplies the swept voltage, terminal 2 a constant bias voltage. The currents of both terminals are measured.
  • B1500 MOSFET Gate Sweep: Sweeps the gate-source voltage at a constant drain-source voltage and measures the drain current (I_D vs. V_GS) to determine the threshold voltage and the transconductance.
  • B1500 MOSFET Output Characteristics: Sweeps the drain-source voltage at several fixed gate-source voltages and measures the drain current (I_D vs. V_DS) to determine the on-resistance and the saturation behavior.
  • B1500 CV Sweep: Measures the capacitance as a function of the DC bias voltage with the MFCMU. The impedance model (Cp or Cs) and the secondary parameter (G, Rp or Rs) are configurable.
  • B1500 CV Correction: Enables or disables the stored open, short and load correction data of the MFCMU.

âš™ Setup#

Info

The package file will be made available for download after purchase.

Install the package file (*.mmpkg) with the package manager on the system where Measmatic is installed (see Overview→Setup for more information on how to install an extension package).

Measmatic does not talk to the B1500 directly; an auxiliary software component is necessary to enable remote interfacing over a network. This functionality is provided by the ATV Reflex software, which must be installed directly on the Keysight B1500 and is reached by Measmatic via TCP/IP.

🧰 Usage#

After the extension package is installed, the tests can be found in the test library view under the category B1500. Before running the tests, make sure the ATV Reflex is running on the B1500, then add a Keysight B1500 device in the Device manager and connect it. The SMU and CMU channels used by the tests are selected by their slot number in the test UI and must match the modules installed in the B1500.
