HP-IB Status Commands
This chapter gives a list of the HP 8153A HP-IB commands and queries used for

The Statius Registers
The building blocks of the status information circuitry are three types of
register, and two kinds of transition filters. These registers and filters are
grouped together to make a node. Each node has a condition register, a positive
transition register, a negative transition register, an event register and an enable
register.
