Instrument Firmware
The instrument firmware contains all the software required to operate all the
instrument functionality. This includes the basic instrument functionality and
all the optional functionality and modes. To see what version of the instrument
firmware is currently being used press Utility, Instrument Info, Diagnostic Info

Hardware Versus Firmware

All N5166B instruments must have firmware version B.01.80 or newer.
While it is always advised to use the latest version of the instrument firmware
that is available, there are times that an older version is required for one reason
or another. However, there are certain hardware versus firmware dependencies
that exist that need to be considered before using a version of the firmware
other than the latest. While these should all be covered in service notes, the
dependencies that existed as of the printing of this guide are shown in
