Agilent Technologies E1470A user manual Relay Control Registers

Relay Control Registers

These registers control the individual E1470A relays. When a “1” is written to a bit, the relay controlled by that bit becomes SET (COMMON to NO). When a “0” is written to a bit, the relay controlled by that bit becomes RESET (common to NC, the power-on state). All bits are “0” at power-on and reset. Reading a bit returns the state of that bit.

The left-hand relay assembly (when viewed from the front panel of the of the module) has relays K000 through K133. The right-hand relay assembly has relays K201 through K331.
