237 Keithley Sourcemeter

Used
The 237 is a Sourcemeter from Keithley. Source meter instruments are a type of electronic test equipment that measures and logs precise voltage and current data. Source meters collect information with high accuracy, ideal for current-voltage (I-V) characterization, semiconductor testing, and testing devices with both positive and negative current source values.

The Model 237 Source-Measure Unit (SMU) is a fully programmable instrument, capable of sourcing and measuring voltage or current simultaneously. This system is really four instruments in one: voltage source, current source, voltage measure, and current measure.

The Model 237 will source voltage from 100µV to 1100V, and current from 100fA to 100mA. It can also measure voltage from 10µV to 110V and current from 10fA to 100mA. In the higher voltage range, current source and measure is 10mA maximum.

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 instrument very quickly. Sweep parameters 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 operations: CREATE, APPEND, and MODIFY. These allow the user to select waveform parameters, combine multiple waveforms, and select and change any points in a waveform previously crea - ted or appended.

The Model 237 outputs and inputs are fully guarded, 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 ±200V from ground.
