a. Agilent N2265A combines a 4 x 4 matrix and a 16-bit digital I/O into one module. It can be operated as two separate modules.
b. With chassis of all instruments connected, and with Low Terminal of the input connected to Low Terminal of the output (either
directly or via Agilent 3499A/B/C switching channels).
