Midv-655

| Specification | Detail | |---------------|--------| | Channels | 8 (independent, selectable as single‑ended or differential). | | Voltage Range per Channel | ± 0.1 V – ± 655 V (resolution 10 µV). | | Accuracy | ± 0.02 % FS (full scale) + 5 µV (offset). | | Sampling Rate | Up to 200 kS/s per channel (burst mode) or 10 kS/s continuous. | | Input Impedance | > 10 MΩ (single‑ended) / 1 MΩ (differential). | | Bandwidth | 0 – 1 MHz (‑3 dB). | | Triggering | Edge, level, or window trigger on any channel; multi‑channel coincidence possible. | | Data Interface | USB‑3.0 (high‑speed), Ethernet (10/100 Mbps), optional GPIB (via retrofit kit). | | On‑Board Storage | 4 GB SSD (≈ 2 TB of raw data at max rate, compressed). | | Power Supply | 100–240 VAC, 50/60 Hz, internal 48 VDC regulator; optional redundant PSU. | | Environmental Rating | 0 °C – 55 °C, 10 %– 90 % RH (non‑condensing). | | Safety Certifications | IEC 61010‑1, IEC 61010‑2‑4, UL 61010‑1, CE. |

  • Install in Rack

  • Connect Measurement Leads

  • Power‑On and Basic Calibration

  • Install Software

  • Configure a Simple Acquisition (Python example)

  • import midvpy as mv   # pip install midvpy (bundled with Suite)
    # Connect (auto-detect over USB)
    dev = mv.Device()
    # Set channel 1 to measure -10 V to +10 V (example)
    dev.set_range(channel=1, low=-10, high=10)
    # Set sampling rate and mode
    dev.set_sampling(rate=10_000, mode='continuous')   # 10 kS/s per channel
    # Arm and start acquisition
    dev.arm()
    dev.start()
    # Grab 1 s of data from channel 1
    import numpy as np
    data = dev.read(channel=1, duration=1.0)   # returns a NumPy array
    # Simple RMS calculation
    rms = np.sqrt(np.mean(data**2))
    print(f"Channel 1 RMS = rms:.6f V")
    # Stop and disarm
    dev.stop()
    dev.disarm()
