DC205 – PRECISION DC VOLTAGE SOURCE

The DC205 low-noise, high-resolution DC voltage source is the right tool when a precision bias source is needed. Its bipolar, four-quadrant output delivers up to 100 V with 1 µV resolution and up to 50 mA of current. In 4-wire mode (remote sense), the instrument corrects for lead resistance delivering accurate potential to your load. The DC205’s output stability is a remarkable ±1 ppm over 24 hours. With its linear power supply, there is no need to worry about high-frequency noise.

Features:

  • ±100 VDC range
  • True 6-digit resolution
  • 1 ppm/°C stability
  • 0.0025 % accuracy (1 yr.)
  • Triggerable voltage scans
  • Low-noise design
  • Linear power supply
  • RS-232, USB and fiber optic interfaces

True 6-Digit Resolution

The front-panel display of the DC205 lets you set voltage with true 6-digit resolution. There are three voltage ranges to choose from: ±1 V, ±10 V and ±100 V which allows voltage settings from 1 µV to 100 V — eight orders of magnitude!

Low-Noise Design

The DC205 has outstanding noise characteristics – on the 1 V range, the rms noise is less than 1 µV (0.1 Hz to 10 Hz). It is also accurate to 0.0025 % over a one year period, and it has excellent temperature stability with a specification of less than 1 ppm/°C. The design even features linear power supplies rather than switching power supplies, so switching frequency interference can never be a problem. Click here for a comparison between the DC205 and the Yokogawa 7651.
