The Model 237 Source-Measure Unit is a fully programmable instrument, capable of sourc ing and
measuring voltage or current simultaneously. This system is really four instruments in one: voltage
source, current source, voltage measure, and current measure.
<\/span>Applications
<\/span>This SMU instrument addresses a wide variety of applications, including the characteri zation of semiconductor devices and the measurement of leakage currents or insulation resistance. It can be used
standalone on a bench, in a test rack with PC control, or integrated with our Model 4200-SCS for
high voltage semicconductor characterization.
<\/span>Wide Dynamic Range
<\/span>The Model 237 will source voltage from 100\u00b5V to 1100V, and current from 100fA to 100mA. It can
also measure voltage from 10\u00b5V to 110V and current from 10fA to 100mA. In the higher voltage
range, current source and measure is 10mA maximum.
<\/span>Selectable Sweeps of Voltage and Current
<\/span>The Model 237 can be programmed to perform source-measurements as a function of a stepped
voltage or current. Voltage and current can be swept linearly, logarithmically, or pulsed. The START,
STOP, STEP method of setting sweep parameters allows operators to become proficient at using the
instru ment very quickly. Sweep para me ters may be appended (APPEND key) to obtain more complex
test sequences.
Creating custom sweeps of voltage or current is
facilitated by the use of three waveform opera tions: CREATE, APPEND, and MODIFY. These
allow the user to select waveform parameters,
com bine multiple waveforms, and select and
change any points in a waveform previously crea –
t ed or appended.
<\/span>Fully-Guarded Four-Terminal
Measurements
<\/span>The Model 237 outputs and inputs are fully
guard ed, and the units are configured to allow
four-terminal measurements. Two-terminal measurements are also available for more standard test
procedures. These outputs can be floated up to
\u00b1200V from ground<\/span> <\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"excerpt":{"rendered":"
