Differences Between Prior and Current Revisions

of the HP 53131A/132A

If you have an HP 53131A containing one of the prior firmware revisions (3317,
3335, or 3402), read the subsection below titled “HP 53131A Containing
Firmware Revisions (3317, 3335, or 3402) ” to get an overview of the differences
between the earlier firmware revisions and current firmware revision.

If you have an HP 53132A with a serial number prefix  below 3646, read the
subsection titled “HP 53132A Time Interval Delay Arming ” on page 1-5.

Note that throughout the guide, differences between the earlier and current
firmware revisions are noted where applicable.

There are four main areas that differ:

•

 

Calibrations

•

 

Measurements

•

 

Statistics

•

 

HP-IB Commands

If your Counter contains  other than the current firmware revision, the following
calibration features are different:

•

 

The calibration functions are  in the Utility menu  instead of the Calibration
menu, which is accessed by pressing and holding the front-panel  Utility
key and then cycling  POWER key.

•

 

Calibrations are not protected by a security code.

•

 

A calibration count  does not exist to aid in monitoring the number of
calibrations performed.

•

 

A more accurate Time Interval calibration (FINE TI) is  not available.

See the section titled “Using the Calibration Menu” in Chapter 2 of the  HP
53131A/132A Operating Guide for details.
