Assembly Replacement Procedures
A27 H1G Assembly (Option H1G)
A27 H1G Assembly (Option H1G)
There are two versions of Option H1G hardware that have been installed in the
instrument. The early version is no longer available. Only the latest version is
available for repair purposes.
The early version is identified by the presence of the rear panel connector IF 2
IN, and a semi-rigid jumper cable that connects IF 2 IN to IF 2 OUT.
The latest version of Option H1G hardware only has the rear panel IF 2 OUT
connector. The jumper cable is not present. Also the coaxial cable input
/output connections on the H1G assembly have been re-color coded, which
means you will need to remove and replace color bands on some flex coax
cables when replacing the early H1G hardware with the latest version. The
latest H1G assembly is provided as a replacement kit that includes a hole plug
and the cable color bands. These color bands and hole plug are only required if
you are replacing the early version H1G assembly.
