Power Supply and Measurement Safety
•
Power Supply Safety
This instrument can output high currents and voltages. Make sure that the load or
device under test can safely handle the output current and voltage. Also, make sure
that the connection leads can safely withstand the expected currents and are
insulated for the expected voltages.
The instrument outputs may be connected so as to float relative to earth ground.
Isolation or floating voltage ratings are indicated on the instrument, near the output
terminal or the Circuit Common terminal. There is the danger of electric shock by
touching the floated measurement terminals. Keep in mind it to protect yourself. And
it is a reason of using the recommended accessories.
•
Voltage/Current Measurement Safety
Multimeters and other instruments capable of measuring high voltages and currents
are subject to specific safety concerns because of the circuits to which they may be
connected. To safely use these instruments, you need to understand the markings on
the instrument near the input terminals, which include the Protection Limits and the
IEC Measurement Category.
•
Protection Limits
Keysight multimeters and other voltage measurement instruments provide protection
circuitry to prevent damage to the instrument and to protect against the danger of
electric shock, provided the Protection Limits are not exceeded. To ensure safe
operation of the instrument, do not exceed the Protection Limits shown on the input
terminals.
•
Source/Monitor Terminals
Source/monitor unit, SMU, can simultaneously perform DC voltage or current output
and measurement. Typical SMU has the Force, Guard, Sense, and Circuit Common
terminals as shown below. Normally the Force, Guard, and Sense terminals are the
same potential. Voltage marked around the terminals indicates the Protection Limits.
Force and Sense must be connected to a terminal of a device under test for the Kelvin
connection which is effective for high current measurement and low resistance
measurement. For the non-Kelvin connection to ease the connections, connect Force
only. Do not connect Sense. It must be opened.
Guard should be extended to around the device terminal for reducing leakage current
caused by a coaxial cable used. Guard must be never connected to anything at the
device side.
Circuit Common should be connected to shielding of the coaxial cable used.
The following image is the Kelvin triaxial connector of Medium Power SMU.

Working in Comfort
To optimize your comfort and productivity, it is important that you set up your work area
correctly and use your instrument properly. With that in mind, we have developed some
set-up and use recommendations for you to follow based on established ergonomic
principles. Improper and prolonged use of keyboards and input devices are among those
tasks that have been associated with repetitive strain injury (RSI) to soft tissues in the
hands and arms. If you experience discomfort or pain while using the instrument,
discontinue use immediately and consult your physician as soon as possible. For more
information on RSI you may wish to consult the About Repetitive Strain Injury section.
Please study the recommendations described below. Included there are references to
relevant parts of international standards, regulations and guidelines, such as ISO 9241
and the European Community Display Screen Equipment directive. You may also wish to
consult your employer’s human resources department or other relevant departments for
guidance specific to your company.
About Repetitive Strain Injury
Because your comfort and safety are our primary concern, we strongly recommend that
you use the instrument in accordance with established ergonomic principles and
recommendations. Scientific literature suggests that there may be a relationship between
injury to soft tissues -especially in the hands and arms- and prolonged improper use of
keyboards or other equipment requiring repeated motions of the hands and forearms.
This literature also suggests that there are many other risk factors that may increase the
chance of such injury, commonly called Repetitive Strain Injury.
What is RSI?
Repetitive Strain Injury (RSI -also known as cumulative trauma disorder or repetitive
motion injury) is a type of injury where soft tissues in the body, such as muscles, nerves,
or tendons, become irritated or inflamed. RSI has been a reported problem for those who
perform repetitive tasks such as assembly line work, meatpacking, sewing, playing
musical instruments, and computer work. RSI also has been observed in those who
frequently engage in activities such as carpentry, knitting, housework, gardening, tennis,
windsurfing and lifting children.
What causes RSI?
The specific causes of RSI have not been established. Nevertheless, the incidence of RSI
has been associated with a variety of risk factors, including:
•
Too many uninterrupted repetitions of an activity or motion.
•
Performing an activity in an awkward or unnatural posture.
•
Maintaining static posture for prolonged periods.
•
Failing to take frequent short breaks.
•
Other environmental and psychosocial factors.
In addition, there have been reports associating the occurrence of RSI with the use of
keyboards, mice, and other input devices. Also, certain medical conditions, such as
rheumatoid arthritis, obesity and diabetes, may predispose some people to this type of
injury.
What if I experience discomfort?
If you are experiencing any discomfort, seek professional medical advice immediately.
Typically, the earlier a problem is diagnosed and treated, the easier it is to resolve.
Mice and Other Input Devices
Various aspects of using mice and other input devices may increase your risk of
discomfort or injury. Observing the following recommendations may reduce that risk.
•
Try to keep your hand, wrist, and forearm in a neutral position while using your mouse
or other input device.
•
If you use your thumb to rotate the ball on a trackball or spaceball, keep it in a
relaxed, natural shape, and maintain a neutral posture in your hand, wrist, and
forearm.
•
Hold the mouse gently by draping your fingers over it. Keep your hand relaxed and
fingers loose. Do not grip the mouse tightly.
•
It takes very little pressure or force from your fingers to activate the buttons or scroll
wheel on your mouse, scrolling mouse, trackball, or other input device. Using too
much force can place unnecessary stress on the tendons and muscles in your hands,
wrists, and forearms.
•
If you are using a scrolling mouse, be sure to keep your fingers and hand in a relaxed,
neutral position when activating the scroll wheel. Also, this type of mouse features
software that can minimize the number of mouse movements or button clicks.
•
When using a mouse, trackball, or other input device, position it as close to the
keyboard as possible, and keep it at the same level as you do not have to stretch while
using it.
•
Be sure to keep your mouse and trackball clean. Regular removal of accumulated
dust and dirt helps ensure proper tracking and reduces unnecessary hand and wrist
motions.

Introduction
Overview
Overview
Keysight B1506A Power Device Analyzer for Circuit Design is a complete solution
that can help power electronic circuit designers maximize the value of their power
electronics products by enabling them to select the correct power devices for their
applications. It can evaluate all relevant device parameters under a wide range of
operating conditions, including IV parameters such as breakdown voltage and
on-resistance, as well as three terminal FET capacitances, gate charge and power
loss.The B1506A has a wide range of capabilities that help it identify substandard
devices under actual circuit operating conditions, including a wide voltage and
current range (3 kV and 1500 A), a wide temperature measurement range (-50 °C to
+250 °C), fast pulsing capability, and sub-nA level current measurement capability.
Its unique software interface presents the user with a familiar device data sheet
format that makes it easy to characterize devices without going through any formal
training. Integrated switching circuitry within the test fixture supports fully
automated testing, with the ability to automatically change between both high
voltage and high current testing as well as between IV and CV measurements. In
addition, a unique plug-in style device test fixture socket adapter eliminates cable
connection and other human-related errors. The B1506A also supports the complete
automation of thermal characterization. This can be accomplished either through the
integrated Thermostream control or via the Thermal Plate. Since the DUT is in close
proximity to the B1506A’s measurement resources, the large parasitics caused by
cable extensions leading to a temperature chamber do not exist. For this reason,
oscillation free ultra-high currents of up to 1500 A can be accurately evaluated at
both low and high temperature.

GNDU - Ground Unit
The ground unit (GNDU) is a 0 V constant voltage source, and used for the
reference of measurement ground. Also the GNDU can sink up to ±4.2 A, so it is
effective for using MPSMU or HVSMU. When the HCSMU, MCSMU, or UHCU is
used, the GNDU must be connected to the Low terminal side to apply the reference
zero voltage. Figure 1-1 is a simplified circuit diagram of GNDU.

MFCMU - Multi Frequency CMU
This section describes typical specification of the multi frequency capacitance
measurement unit (CMU). The CMU performs the impedance measurement and
returns the specified measurement data such as Cp-G.
•
Measurement parameters: See Table 1-16.
•
AC signal, output frequency:
1 kHz to 5 MHz
Setting resolution: 1 mHz (1 kHz to), 10 mHz (10 kHz to), 0.1 Hz (100 kHz to),
or 1 Hz (1 MHz to 5 MHz)
•
AC signal, output level:
10 mVrms to 250 mVrms, 1 mV resolution
•
DC bias:
0 to ± 25 V, using MFCMU internal DC bias
0 to ± 3000 V, using HVSMU and high voltage bias-tee
•
Measurement range:
For the fixed ranging mode, measurement range (impedance range) must be
specified to perform measurement. Table 1-17 shows the available measurement
ranges and the corresponding impedance value. And Figure 1-8 shows the
calculation example of the impedance vs frequency characteristics of a
capacitive load. Use these information to decide the measurement range.
Impedance Z is calculated by the following formula.
Z = 1 / (2 f C)
where f is frequency (Hz) and C is capacitance (F).

or there are the parameters that are not specified in the datasheet, you may
specify the predicted values.
•
Measure the switching device by the I/V measurement software, capacitance
measurement software, and gate charge measurement software at your desired
drive conditions and store the measurement data. Then, the power loss
calculation software read the stored measurement data and extract the required
drive conditions and characteristics parameters for power loss calculation.
This section explains the procedure that specify the measurement data file of DUT.

Creating Custom File
This section introduces a procedure and essentials to create a new ETN DS file to be
fitted to specific devices.
1. After starting this software, select the type of your device and then click the New
Datasheet button in the Identification area.
This reads the data from the selected template, and provides the foundation for a
new ETN DS file.
2. Create a new ETN DS file with an appropriate name using the main menu File >
Save as.
For example, if you specify CustomMOSFET as a new name,
CustomMOSFET.pda-ds.zip file is created.
3. Open the ETN DS file (for example, CustomMOSFET) using the main menu
File > Open. Skip this step if you operate continuously.
4. Customize the measurement conditions and so on with referring to the
“Customization Essentials” below.
5. After finishing all customization, save all setup data and measurement data to
the ETN DS file using the main menu File > Save.
To use the ETN DS file as a template for evaluating same device model, it is
recommended to manage it with keeping from changing. When evaluating each
individual device, use a copy of the ETN DS file
NOTE
During opening the ETN DS file, don’t use the Device Type and New Datasheet
button . If they are used, it rewrites all data by the furnished template.
Customization Essentials

Enter a value of the gate-source voltage to completely change
the DUT to the on-state.
Ig
Enter a limit value of the gate current. This value impacts on the
switching time. Large Ig shortens the switching time, and small
Ig elongates it.
Mark the check box when you want to use the constant current load.
Set the conditions for driving the gate of the transistor for the constant current load,
that is the source of the on-state current described in “Drain” on page 4-106.
When you use the resistive load (not use the constant current load), unmark the
check box to disable the constant current load.
LoadVgs(off)
Enter a value of the gate-source voltage to change the transistor
for the constant current load to the off-state.
LoadVgs(on)
Enter a value of the gate-source voltage to completely change
the transistor for the constant current load to the on-state.
Before the gate charge measurement, DUT is completely changed to the on-state.
During this situation, the gate-drain voltage of the transistor is searched from
Vgs(off) to Vgs(on) so that the specified on-state current Id (on) flows. The
transistor is driven by the searched gate-source voltage, and then the gate charge
measurement is executed. Where, “DUT is completely changed to the on-state”
means the state that the gate-source voltage of the DUT is set to the Vgs(on) entered
for the gate drive condition.

Switching Waveform
This page shows the switching waveforms of DUT to observe the switching
behavior. And, you can also set detailed parameters before the measurement. To
display this page, click the Switching Waveform tab.
The gate charge characteristics is calculated from the gate current and waveform
data of the gate-source voltage obtained from the switching, and the calibration data.
There are the following switching modes.
•
“High Current Switching Mode”
UHCU or HCSMU is used as a power supply to force the on-state current
specified in “Drain” to DUT via the constant current load specified in “Current
Load”.
And, the applied voltage is determined as follows, depending on the off-state
voltage specified in “Drain”.
•
If the off-state voltage is within the output voltage range of UHCU/HCSMU,
they force the specified voltage. The maximum output voltage of UHCU is
60 V and it of HCSMU is 20 V at 20 A range.
•
If the off-state voltage exceeds the output voltage range of UHCU/HCSMU,
UHCU forces 60 V and HCSMU forces 20 V.
If you don’t use the constant current load, the applied current is determined from
the load resistance, on-state resistance of DUT, and the output voltage of the
power supply.
•
“High Voltage Switching Mode”
HVSMU is used as a power supply to force the off-state voltage specified in
“Drain” to DUT.
This page has the graph area to display the time-domain switching waveforms and
the advanced setup area to set the detailed parameters for the measurement in the
above modes. To switch the mode, click the tab (High Current or High Voltage) on

Executing Measurement in Synchronization with
Thermo-trigger List
You can execute a DUT characteristics measurement using one of the following
software in synchronization with the thermo-trigger list. Along the progress of the
thermo-trigger list, the temperature around DUT is controlled and the measurement
is executed if it reaches within the target temperature window.
•
Datasheet Characterization Software
•
I/V Measurement Software
•
Capacitance Measurement Software
•
Gate Charge Measurement Software
If you use the ThermoStream to control the temperature around DUT, do the
following preparation for the measurement in synchronization with the
thermo-trigger list.
•
On the measurement software: 
Set up the measurement conditions, and confirm the measurement is
successfully executed at normal temperature. And then, save the setup data to a
setup file or measurement data file.
•
On the thermal monitor/control software: 
Set up the thermal condition and ThermoStream control, and create a
thermo-trigger list in the control mode. And then, save the setup data to a setup
file.
After this preparation, follow the step below to execute the measurement in
synchronization with the thermo-trigger list.
1. Start the thermal monitor/control software.
2. Switch the view mode to the Control mode.
3. Open the prepared setup file on the thermal monitor/control software.
4. Start the measurement software.
5. Open the prepared setup file or measurement data file on the measurement
software.
6. Click Start tool button in the toolbar (or select Trigger > Start menu) on the
thermal monitor/control software. The thermo-trigger list is executed.

7. Click Start tool button in the toolbar (or select Measurement > Start menu) on
the measurement software.
At this time, the measurement is not executed, and waits until the temperature
reaches within the target temperature window. Along the progress of the
thermo-trigger list, the temperature around DUT is controlled and the
measurement is executed if it reaches within the target temperature window.
If you use the thermal plate to control the temperature around DUT, you need to
control the thermal source manually. Even in this case, you can execute the
measurement in synchronization with the thermo-trigger list using the similar
manner as above. The following shows the differences.
•
Preparation on the thermal monitor/control software: 
Set up the thermal conditions only, and create a thermo-trigger list that has only
thermal condition steps, not thermal control steps.
•
With checking the present temperature around DUT and the next target
temperature window (thermal condition) using the monitor mode panel of the
thermal monitor/control software, control the thermal source manually.
When the present temperature reaches within the target temperature window, the
measurement is executed. Wait until finishing the measurement, control the
thermal source again so that the temperature goes to the next target temperature
window.
