Quad-channel bipolar voltage source
⠀⠀⠀⠀⠀⠀⠀⠀⠀
Koheron VREF100 is a quad-channel voltage source that can be adjusted between -5 V and +5 V. It can source or sink up to 40 mA on each channel. Each channel has a coarse and a fine trimmer with a settability of 20 µV. Thanks to its low wideband noise and high stability, the VREF100 can be used to bias sensitive devices such as VCOs or Mach-Zehnder modulators.
