b. All new units built after August 2009, no longer use the N5242-60031 cable that was attached to connector
P1001 and Source 2. As a result of this change, the IF multiplexer boards have had their P1001 connectors
removed. If your instrument contains a N5242-60031 cable, remove it from your instrument.
