Upgrading an 8340/8350 Source

Upgrading an 8340/8350 Source
8340/41 and 8350 series sources are out of support life and are no longer recommended for
use in 8510C systems.
Not all 8340/41 sources are compatible with the 8510B/C. If the serial prefix is not 2505A
or greater, or previously upgraded, the firmware may need to be upgraded to get full
performance (within feature limitations) and a minimum of bugs. For example, with
Nov.82 firmware, if you program CW Single Point, and then change to step or ramp and
back to CW, you will get exactly 5 GHz offset in the RF source frequency.
8340/41 sources with serial prefix 2505A or greater may also need to be upgraded
depending on the 8510C operating system revision used. 8340/41 sources can work with
the newer revisions of 8510C firmware C.07.xx and C.08.xx (within feature limitations and
with a minimum of bugs) provided they have a source firmware date of 1992 or later.
Please consult with your Agilent customer engineer for more information on upgrading a
network analyzer and/or source firmware.
