A method and apparatus for establishing the correct order of probe channels in a logic analyzer is disclosed. Logic analyzers have probe PODS connected thereto, the PODS having a plurality of probe tips connected thereto for further connection to the terminals of a product under test. With this invention, the order of connection of the tips to the terminals can be ignored because the correct order is established via the logic analyzer (LA) itself. A ROM has firmware stored therein for enabling the logic analyzer to establish the correct order of connection. The binary data from each POD is stored in memory. The binary data in memory may be converted to hexadecimal form and stored in the display controller. By using a keyboard, the operator displays, on the LA display, a menu-mode display, which includes a display of the probe channel identifiers for each POD, the identifiers reflecting the actual order of connection of the probe tips to the terminals of the product under test. The operator then displays, on the LA display, a state table display, which is a display of the binary (or hexadecimal) data for each channel for each increment in time. If the probe tips were connected to the incorrect terminals of the product under test, the keyboard is used to display the menu-mode display. Using the keyboard and the display, the operator changes the order of the probe channel identifiers on the display. This compensates for the incorrect order of connection of the probe tips to the terminals of the product under test. The desired state table display is then displayed on the LA.
