In summary, the Keithley 2450 is a 200 V, 1 A, 20 W graphical SourceMeter SMU with a five-inch color touchscreen front panel. It is the fourth-generation member of Keithley's SourceMeter family, built on the proven Model 2400 architecture and optimized for characterizing nanoscale devices, organic semiconductors, printed electronics, and low-power components.
The 2450 is used for current-voltage characterization and functional test across a broad range of modern electronics: nanomaterials and graphene devices, semiconductor wafers and thin films, organic materials, e-inks, printable electronics, LEDs and AMOLEDs, photovoltaics, batteries, and small-signal discrete components.
The 2450 extends the 2400's 200 mV to 200 V voltage range down to 20 mV, and its 1 µA to 1 A current range down to 10 nA. Wideband noise drops to 2 mVrms typical (vs. 4 mVrms on the 2400). The reading buffer scales from 5,000 readings to more than 250,000. Remote interfaces gain USB and Ethernet (LXI) alongside GPIB, and rear inputs move from banana to triaxial for guarded low-current work.
| Specification | Value |
|---|---|
| 20 mV range, source accuracy | ±(0.100% + 200 µV) |
| 200 mV range, source accuracy | ±(0.015% + 200 µV) |
| 200 V range, source accuracy | ±(0.015% + 24 mV) |
| 10 nA range, source accuracy (rear triax) | ±(0.100% + 100 pA) |
| 1 A range, source accuracy | ±(0.067% + 900 µA) |
| Maximum power | 20 W, four-quadrant source or sink |
| Voltage source noise (10 Hz to 1 MHz) | 2 mVrms typical |
The 2450 is the most widely deployed member of Keithley's graphical SourceMeter family. It interoperates with the 2460, 2461, 2470, DMM7510, DMM6500, DAQ6510, Series 2600B, and Series 3700A through TSP-Link — the same channel-expansion bus used in semiconductor parameter analyzer systems and university physics laboratories worldwide.
| Accessory | Description |
|---|---|
| 8608 | High Performance Test Leads |
| USB-B-1 | USB Cable, Type A to Type B, 1 m |
| CS-1616-3 | Safety Interlock Mating Connector |
| CA-180-3A | TSP-Link / Ethernet Cable |

The 2450 integrates a precision power supply, true current source, 6.5-digit DMM, precision electronic load, and a trigger controller in a single instrument. Keithley's TriggerFlow triggering system supports up to 255 block levels for complex test sequences, and a 2400 SCPI compatibility mode lets existing 2400-series test code run unchanged.
