Siglent SPD1168X FAQ

• What is the output range of the Siglent SPD1168X?
  The Siglent SPD1168X provides a single-path programmable DC output from 0 to 16 V and 0 to 8 A, with total output power up to 128 W. This makes it a practical choice for users who need adjustable low-voltage DC power for circuit testing, development, and production support.

• Does the SPD1168X support remote control or automated testing?
  Yes. The SPD1168X includes USB Device and LAN interfaces and is supplied with Easypower PC software. The datasheet also states support for SCPI and a LabVIEW driver, making the unit useful for remote computer control and automated test setups.

• How does the 4-wire sense function help during testing?
  The SPD1168X includes a 4-wire sense compensation output mode that uses a separate measurement circuit to compensate for voltage drops caused by long cables or high-resistance connections. With up to 1 V maximum compensation, this feature helps the power supply deliver more accurate voltage at the load.

• How do you program a timed voltage or current sequence on the SPD1168X?
  To program a timed voltage or current sequence on the Siglent SPD1168X, use the front-panel Timer menu to input up to 50 distinct steps of specific voltages, currents, and durations, then press Enter to run the automated sequence and view the real-time graphical waveform trend on the 2.8-inch display.
