Quick start guide / documentation
PC/Storage: At high sampling rates, data volume grows extremely fast. Use high-speed SSD storage and confirm the target recording duration before testing.
EMI best practice: Use proper shielding/grounding and keep sensor cables short where possible to reduce coupling noise.
Triggering: Configure level/edge trigger conditions early, then verify trigger stability with a short test run before long recording.
Power in field: When using battery operation, plan power budget and test duration (battery runtime depends on load and is not specified in the provided sheet).
Q1: Why are there “50–100M” and “1–50 MHz bandwidth” mentioned together?
A: “50–100M” refers to the sampling rate range (50–100 MHz), while “1–50 MHz” is the signal bandwidth. Bandwidth indicates the frequency content the system can effectively capture; sampling rate determines time resolution and anti-aliasing requirements.
Q2: Can all channels sample at 100 MHz at the same time?
A: Yes. The sheet states all channels synchronous parallel sampling within 50–100 MHz.
Q3: How long can it record at 100 MHz?
A: The provided spec says it supports 100 MHz continuous acquisition for 5+ minutes with real-time storage to a PC. Longer duration depends on PC storage throughput and capacity.
Q4: What input ranges does it support?
A: The provided spec lists voltage input ±1 V and ±5 V.
Q5: What excitation is available?
A: It supports constant-voltage excitation and indicates +12 V / +24 V optional, with 24 V supported.
Q6: What trigger modes are supported?
A: The spec includes software/internal/external triggers, plus positive/negative delay triggering and recognition of levels and edges (high/low, rising/falling).
Q7: Is it portable for field testing?
A: Yes. It supports AC220V/50Hz or DC12V, and also supports built-in 12.6 V lithium battery operation; the enclosure is 230×140×80 mm and 2 kg.
