The Tektronix LA501 is a logic analyzer plug-in for the TM500 system.

It has a cable-attached, passive 16-channel probe, the P6450, and outputs analog X/Y/Z signals for an external oscilloscope or X/Y monitor. Alternatively, channels 0-3 can be switched to four BNC connector inputs with 1 MΩ impedance intended for external ×10 probes.

The LA501W was a bundle of the LA501 with a WR501 connected internally to provide word recognition trigger as well as data acquisition. In this case, there is no P6450 probe; instead, one or two P6451 probes are attached to the WR501.

The LA501 provides only a timing diagram with clock tick marks on the traces, and analog zoom/pan controls for focusing on a particular trace or detail. Each channel can be positioned anywhere vertically to allow for timing comparisons.
