Agilent 85620A Mass Memory Module

If the mass memory module functions are missing when you press the

MODULE key, check the rear panel of the spectrum analyzer. In this

case, the message MODULE NOT FOUND will appear on the display. The

mass memory module should be attached to the rear panel. When it is

attached, the spectrum analyzer has internal memory and a broader

range of commands available. The additional commands are

documented in the Agilent 85620A manual.

It is possible to get a different set of functions from a given mass

memory module, depending on the ﬁrmware revision of the host

spectrum analyzer. In spectrum analyzers with ﬁrmware revision

>941028, the ﬁrmware that controls the mass memory module actually

resides in the host spectrum analyzer and contains a more recent set of

features and functionality. If that same mass memory module is

installed on a host spectrum analyzer with ﬁrmware revision 941028 or

earlier, the ﬁrmware that resides in the mass memory module (revision

A, B, or C) will control the features and functionality of the module.

To check the mass memory module ﬁrmware version, press the

MODULE

key. An earlier spectrum analyzer displays ﬁrmware revision 910116 or

earlier. A later spectrum analyzer displays ﬁrmware revision 950829 or

later.
