Figure 5-1. Status Register Overview
STB Status Byte Register
The Status Byte (STB) register is the main register where information from other
status registers and from the output queue are collected. The value of STB register is
reset after powering up the Calibrator, or after sending the *CLS command. This
command resets all STB bits except the MAV bit, which remains set if the output
queue is not empty. The STB register value can be read via a serial message or the
general query *STB?.
