This Keithley 2200-60-2 is absolutely beautiful! It is not new but may as well be.

The Series 2200 Programmable DC Power Supplies provide a wide range of voltage outputs to address the testing and characterization of components, circuits, modules, and complete devices whether you are in a research laboratory, in design and development, or in production test. The Series 2200 consists of five models with output voltages from 20V to 72V that can deliver 86W, 96W, 100W, and 150W of power. In addition, these power supplies can act as constant current sources as well as constant voltage sources. The Series 2200 power supplies offer an excellent combination of performance, versatility, and ease of use that allow you to obtain quality test data as quickly as possible. They perform as effectively in automated test systems as they do in manual instrument configurations.

This Keithley 2306 is literally like new. Comes with manuals, power cord, bench top kit installed, rack mounts  and connectors included. It has been fully tested and works perfect.

The 236 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, voltage measure, current source, and current measure. The unit will source voltage from 100 V to 110 V and current from 100 fA to 100 mA. It can also measure voltage from 10 V to 110 V and current from 10 fA to 100 mA.

Keithley 237 High Voltage Source Measure Unit  The photos are for illustrative purposes. The actual unit you receive may be a different unit but they are all in very good condition with recent calibrations. They are guaranteed to perform 100%. Included with the purchase will be  one, 6.6 ft. (237-ALG-2) Low Noise Triax cable.  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 237 sources 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. It 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 created or appended. The 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.  Features:  Four instruments in one (voltage source, voltage measure, current source, current measure)  10fA, 10µV measurement sensitivity  1100V source and measure  Standard and custom sweep capability including pulse  1000 source/measurements per second  Four quadrant source operation  Internal 1000-reading memory  Voltage range maximum values: ±1.1 V, ±11 V, ±110 V, ±1100 V  Current range maximum values: ±1 nA, ±10 nA, ±100 nA, ±1 µA, ±10 µA, ±100 µA, ±1 mA, ±10 mA,

Options not included but available 10 ft Triax cables (p/n 7078-TRX-10) 3 slot low noise triax cable 

The 238 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, voltage measure, current source, and current measure.

Applications:

These instruments address a wide variety of applications, including the characterization of semiconductor devices and the measurement of leakage currents or insulation resistance. They are particularly useful as source and measuring instruments in automated test equipment (ATE).

This Keithley 2400 is impeccable. Looks like new. 

Keithley’s SourceMeter family are source measurement unit (SMU) instruments designed specifically for test applications that demand tightly coupled sourcing and measurement. All SourceMeter models provide precision voltage and current sourcing as well as measurement capabilities. Each SourceMeter instrument is both a highly stable DC power source and a true instrument-grade 6½-digit multimeter. The power source characteristics include low noise, precision, and readback. The multimeter capabilities include high repeatability and low noise. The result is a compact, single-channel, DC parametric tester. In operation, these instruments can act as a voltage source, a current source, a voltage meter, a current meter, and an ohmmeter. Manufacturers of components and modules for the communications, semiconductor, computer, automotive, and medical industries will find the SourceMeter instruments invaluable for a wide range of characterization and production test applications
