D5a#

Description#

The D5a module is a 16 channel DC voltage source dedicated to setting gate-voltages on samples. Each channel on the D5a is controlled by the same 18-bit DACs (Digital to Analog converters).

A D5a voltage module.

On the front of each D5a module you find:

  • 16 x MCX: DC voltage source with software-selectable range (±4, ±2, +4 V), 18-bit resolution, 550 Ohm output impedance with a 100 KHz low-pass filter. The compliance current is ±7.3 mA.

  • 1 x switch: Switch to ramp all outputs down to zero volts.
