The instrument will attempt to read known constants from
predelined memory locations in the mm-wave source module
NOVRAM (non-volatile RAM and ROM). An error condition occurs
if the constants are not read back correctly, and the instrument
reverts back to its stand-alone mode.
905
-300, “Device specific error;Bad Checksum in MM Head(905)”
The error condition occurs when the checksum test fails on the
mm-wave source module NOVRAM. If the error occurs at power up
or instrument preset, instrument will revert back to stand-alone
mode.
