【FAQ】

Q: What is the maximum sampling rate of the 190-504 III-S?
A: It supports up to 5 GS/s in single-channel mode, with lower per-channel rates when multiple channels are active.

Q: Can it run long-term logging over hours or days?
A: Yes, via ScopeRecord and TrendPlot modes, it supports long-duration waveform logging and trend capture.

Q: Are the input channels isolated?
A: Yes — all four inputs are floating and isolated from each other and from ground, enabling safe measurements in complex circuits.

Q: What safety rating does this instrument have?
A: It is rated for CAT III 1000 V and CAT IV 600 V suitable for industrial environments.

Q: How is data transferred to PC?
A: Through isolated USB ports and optionally via Wi-Fi (with adapter) for data transfer and PC interface usage.
