Scientech technologies provides a range of logic analysers. La-4000 & la-5000 series: maximum sampling rate - 500 mhz, deep data buffers [up to 512k samples per channel/500 mhz]; stores up to 512k events surrounding the trigger point; up to 160 data input channels; high impedance probes [200kohm/5pf]. It can works with up to 8 different logic thresholds including ttl, ecl, 3v logic, coms, or rs-232 at the same time with multiple threshold voltage selections; external trigger output; and high data bandwidth of 100 mhz.
