Firmware Revision Query
The instrument has three microprocessors for control of various internal
systems. Each plug-in module also has its own on-board microprocessor.
You can query the instrument and each module to determine which
revision of firmware is installed for each microprocessor.
• The instrument returns three revision numbers. The first number is
the firmware revision number for the measurement processor; the
second is the input/output processor; and the third is the front-panel
display processor. For each plug-in module, the instrument returns
one revision number for the on-board processor.
