Вот сегдня в мыле пришло: Digilent Digital Discovery до 32 входов, до 800Ms при 8 входах. 100MHz. Есть на маузере за 175 евро. Может и генерить сигналы. https://reference.digilentinc.com/reference/instrumentation/digital-discovery/reference-manual
9.1. Logic Analyzer 24 high-speed input channels (DIN0…23), accessible through one 2×16 connector, used with the Logic Analyzer in WaveForms (560kΩ||10pF) 16 digital I/Os (DIO24…39) arranged in two Pmod-style (2×6) connectors, used with the Logic Analyzer in WaveForms 1) 800MSps input sample rate when using maximum 8 inputs (and the High Speed Adapter), 400 MSps with maximum 16 inputs (with the High Speed Adapter), 200MSps and lower with maximum 32 inputs 2) User programmable input and output LVCMOS voltage levels from 1.2V to 3.3V 3) (5V compatible 4) ) 100MHz signal input bandwidth 2Gbit DDR3 acquisition buffer for Logic Analyzer Multiple trigger options including pin change, bus pattern, etc 5) Digital Bus Analyzers (SPI, I²C, UART, Parallel) 9.2. Multi-purpose Digital I/O 16 digital I/Os arranged in two Pmod-style (2×6) connectors. Each of the 16 pins can be configured for input (Logic analyzer) or set as output 6). Algorithmic pattern generator (no buffers used) 7) Custom pattern buffer/ch.: 32Ksamples ROM Logic for implementing user defined Boolean functions and State Machines Bus Protocol Controllers (SPI, UART, I²C) 100MSps max. output sample rate (50MHz maximum output frequency). Automatic or manual strength and slew settings for outputs. 8) User programmable logic I/O levels from 1.2V to 3.3V (5V compatible) 9),10). 9.3. Other features USB bus powered User power supplies, 1.2V to 3.3V, available in the two Pmod-style connectors (100mA max) Twisted wire high-speed cable option for input channels to insure signal integrity Free WaveForms software runs on Windows, MacOS, and Linux Cross-triggering between Logic Analyzer, Pattern Generator or external trigger Data file import/export using standard formats 80X80X25mm, 80g (without accessories) includes: USB cable, fly-wire accessory
