    Figure 1-1). The component module contains 256 latching relays implemented as four 4 X 16 submatrixes. The terminal ,modules convert these submatrixes into a 16 X 16 (Keysight E1465A), 4 X 64 (Keysight E1466A), or 8 X 32 (Keysight E1467A) matrix. The terminal module matrixes are two-wire crosspoint switching (HI and LO).
