The SRS DC215 DC Voltage/Current Source lets you generate extremely low-noise voltage and current signals with the precision and accuracy needed in the toughest applications. The instrument also measures and displays voltage and current, making it a convenient signal monitor in addition to being a precision source.

The DC215's bipolar, four-quadrant output lets you source and sink voltage (±32 V) and current (±240 mA). In four-wire mode, the instrument corrects for lead resistance delivering accurate voltage and current to your load.

Up to 1000 step sequences can be output, which are controlled by internal or external triggers. Voltage and current measurements can be logged to the USB port or one of the computer interfaces.

Low-Noise Design
In addition to its precise 5½ digit resolution, the DC215 is highly stable and accurate. It also has impressive noise performance: less than 75 µVpp (10 V range) and 70 nApp (10 mA range).

And with its custom linear power supplies, there is no need to worry about switching frequency interference — there isn't any.

Biploar, Four-Quadrant Output
The DC215 can source or sink voltage or current and is fully floating. Two-wire or four-wire operation can be selected. In four-wire mode (remote sense), the instrument senses the output voltage at the load eliminating the effect of lead resistance. Programmable voltage and current limits can protect sensitive loads.

Voltage and Current Monitoring
Unlike some competitive models, voltage and current measurement & display is a standard feature of the DC215. A common use of this feature is to monitor current while generating voltage, or monitor voltage while generating current. These measured values can be logged to the USB port or to a computer.

Sequencing and Data Logging
The DC215 lets you define up to 1000 step output sequences, with full control of the output range and value of each step. Sequences can be created on the DC215 directly, or downloaded from a USB drive or over one of the computer interfaces. Internal and external step triggers and ramping control the output sequence.

Multi-Unit Synchronization
When channel expansion is needed, the DC215 has built-in digital I/O for synchronizing multiple units. It also supports synchronization to external DMMs or other devices.

Computer Interfaces
The DC215 is fully programmable over its RS-232, GPIB and Ethernet interfaces. All functions of the instrument can be set or read via the interfaces.
