Saleae Logic 16 Overview

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

• Automated testing against long pseudo-random waveforms at 1MHz and 25MHz, run at 1.8V, 2.5V, 3.3V and 5V.
