Moody's noted that HPIB's deposit ratings would probably move in lockstep with HP's ratings.
This paper presents the software and hardware design and implementation of a user-friendly GUI HPIB data acquisition, analysis and presentation system for the HP8510C Network Analyzer.
The action follows Moody's recent announcement of the downgrade of HPIB's
HPIB is used in the manufacturing of tyres, lubricants and other petroleum-based products.

The design features only four buttons for function control (frequency, power, offset frequency and offset power) and four buttons for setting the operational parameters (resolution, sample rate, number of averages and HPIB address).
By the 1980s, the IEEE 488 Instrument Control Bus, also known as the Hewlett-Packard Interface Bus (HPIB) or General-Purpose Interface Bus (GPIB), was standard on most equipment.
S-parameters were read through HPIB by a computer using an in-house program.

An important early move came in 1972, when Hewlett-Packard (HP) introduced the HPIB, which in 1975 was formalized into IEEE-488, a hardware protocol to standardize the interface connecting instruments to each other.
