HP-IB Address Selection
The HP-IB address is selectable using rocker switches on the rear-panel of the Phase Noise Interface.
These rocker switches are set up in a binary format with switch number 1 as the least significant digit
and switch number 5 as the most significant digit. (Switches 6 and 7 are not used.) Any one of 31
HP-IB addresses can be set (00 through 30).
The address of the HP 11848A is set to 20 at the factory (switches 3 and 5 high; 16 + 4 = 20). Refer
to Figure 3.
