Installing and Configuring the E1459A
Terminal Block
The Keysight E1459A includes both the input / interrupt module and a
screw-type standard terminal block. User inputs to the terminal block are to the
High and Low for each channel, +5Volt, Ground, Data Valid (DAV0 - DAV3),
External Trigger (XTRIG0 - XTRIG3), and Interrupt (INTR0 - INTR3) .
Figure 9 shows the Keysight E1459A's standard screw-type terminal block
connectors and associated channel numbers. Use the guidelines below to wire
connections.

– Be sure the wires make solid connections in the screw terminals.
– Maximum terminal wire size is No. 16 AWG. When wiring all channels, a
smaller gauge wire (No. 20 or 22 AWG) is recommended. Wire ends should
be stripped 5 to 6 mm (0.2 to 0.25 in.) and tinned to prevent single strands
from shorting to adjacent terminals.
To prevent the spread of fire in the case of a fault, use
flame-rated field wiring whenever the input voltage will
exceed 30Vrms, 42Vpeak, or 60Vdc.
