A little more oomph for developers who need it.
对于需要的开发者来说Logic16更有吸引力
Flexible sample rate
Sample 2 channels at 100MHz, 4 channels at 50MHz, 8 channels at 25MHz, or all 16 channels at 12.5MHz.
双通道采样率100MHz，4通道50MHz，8通道25MHz，全部16通道工作是12.5MHz
16 channels
As you might have guessed from the name, Logic16 lets you connect up to 16 of your most troublesome signals.
看到Logic16这个名字，也许你已经想到了，没错！它能让你连接平时头疼的16通道。
Enhanced hardware-side buffer
Logic16 has a much larger hardware-side buffer than Logic, considerably enhancing its reliability for extremely long captures at high speeds.
Logic16比Logic在硬件端有更大的缓冲区，在高速工作长时间的捕捉数据时，极大的提高了可靠性。
Billions of samples
Logic16 can save as many as 10B samples, letting you capture even the most elusive events. No more dealing with frustratingly small sample buffers.
Logic可以存储100亿个样本，甚至能让用户捕捉到容易丢失的事件，不再因为小的样本缓冲区而沮丧！

Input Voltages and Thresholds
- Input voltage range: -0.9V to 6V
- Works with 1.8V, 2.5V, 3.3V, and 5V systems
- Threshold Setting 1 (for 1.8V to 3.6V)
- Input Low Voltage: <= .7V
- Input High Voltage: >= 1.4V
- Threshold Setting 2 (for 5V)
- Input Low Voltage: <= 1.4V
- Input High Voltage: >= 3.6V
- Over-voltage protection to +/- 50V. Not meant for continuous operation outside -0.9V to 6V.

Input Impedance
- 180Kohm || 7pF (typical, approximate)
Maximum Input Bandwidth
- 25MHz square wave
Crosstalk Immunity
- Tolerant of simultaneous switching on up to 8 channels at all voltages.
- Note that unused inputs may exhibit crosstalk if left floating. If desired, unused inputs can be disabled.
Error/Accuracy
- Pulse-width measurement: +/- 10ns @ 100MHz, +/- 20ns @ 50MHz, +/- 40ns @ 25MHz, +/- 80ns @ 12.5MHz
Maximum Sample Rates
- 100MHz when using 2 channels, 50MHz when using 4 channels, 25MHz when using 8 channels, and 12.5MHz when using 16 channels. Note that achieving the highest sample rates requires low USB latency; this may not be achievable on all computers. Performance may improve with the removal of other USB devices, using a different USB host controller, or increasing the software's process priority.
Available Sampling Rates
- 100MHz, 80MHz, 50MHz, 40Mhz, 32MHz, 25MHz, 16MHz, 12.5MHz, 10MHz, 8MHz, 6MHz, 5MHz, 4MHz, 2MHz, 1MHz, 500KHz, 250KHz
Sample Depth
- Up to 10B samples. Absolute maximum depends on data compressibility, available RAM and operating system. 10B samples assumes reasonably high compressibility.
Pre-ship Testing

Safety & Equipment Protection
- For more detail, please see the section Safety & Equipment Protection near the end if the User's Guide
- Logic16 may not be used with DUTs (devices under test) which are not electrically isolated from MAINS (i.e. wall power).
- DUTs which are battery powered, or USB powered (from the same computer as Logic16) are acceptable.
- DUTs powered by AC adapters which have only 2 prongs, and do not have an earth ground connection (such as most "wall warts"), usually provide MAINS isolated power and are acceptable.
- When using USB powered DUTs, special care should be taken to avoid connecting USB sourced power to Logic16's ground, as this provides a short-circuit return path. While both Logic16 and USB ports are designed to survive a short circuit event, care should be taken to minimize its likelihood.
