Nicslab XDAC B-8 8-Channel Source Measurement Unit (XDAC-8MUB-R4G8)
8-channel source measurement unit with 16-bit resolution, bipolar 4-quadrant outputs and USB/Ethernet connectivity.
- Channels / Output Quadrant
- 8 / 4-Quadrant
- Measurement Time
- 30 ms
- Voltage Sourcing Range
- ±2.5 V / ±5 V / ±10 V / ±16 V
- Voltage Resolution
- 0.15 – 1 mV
Overview
The Nicslab XDAC B-8 is a compact 8-channel source measurement system. Each channel independently sources and measures voltage or current, with 4-quadrant operation that allows each channel to both source and sink current. Channels operate in Constant Current (CC) or Constant Voltage (CV) mode.
The instrument is intended for low-power applications, from simple electronic circuits to complex photonic integrated circuits. Voltage readings are available in real time with 0.15–1 mV resolution depending on range, and current readings with 25 µA resolution.
Control and software
The unit is controlled through a graphical user interface or with SCPI commands from Python, MATLAB, LabVIEW or C#. Connection is via Ethernet; a USB-to-Ethernet adaptor is included.
Basic and Premium versions
The Basic version operates on a fixed ±16 V output range. The Premium version adds software-selectable sub-ranges (±2.5 V, ±5 V, ±10 V) for higher-resolution operation, configuration save/upload, CC/CV sequence automation, data recording and per-channel short-circuit protection.
Configurations
The XDAC B-8 is offered with a male pin-header or SMA connector interface, and with a standard single-ended (shared ground) or differential output configuration.
