Rear‑Panel Connections

• BNC Analog Monitor Output (V‑Monitor / I‑Monitor) Outputs a real‑time analog signal proportional to the measured voltage or current. Ideal for connecting to an oscilloscope to observe:

  • Load step response

  • PSU transient behaviour

  • Battery voltage sag

  • Ripple and stability

• Remote Sense Terminals

• RS‑232 / USB (via adapter) for PC control

• Cooling fan exhaust

This BNC monitor output is one of the most useful features of the M9711 for lab work.
