1230
The Tektronix 1230 is a logic analyzer chassis that supports 16 to 64 channels, 100 MHz asynchronous, 25 MHz synchronous. It was introduced in 1989. It is very similar to the Tektronix 1225 and 1220, the difference being board layout and the number of channels.
It uses either P6444 or P6443 16-channel probes.
