308
The Sony/Tektronix 308 is a portable 8-channel, 20 MHz "data analyzer" (logic analyzer) with parallel timing, parallel state, serial (up to 9600 bps) and signature analysis modes.
The 308 uses two probes, the standard P6451 8-channel + clock data acquisition probe, and the optional 16-channel P6406 word recognizer probe. Both use 012-0747-00 cable harnesses to attach to the data source.
