Firmware and Driver Updates
Firmware and driver updates (when available) for the 53210A are available via the
Web. This section contains information for locating and downloading the updates
to your computer, and then installing the updates in the instrument.
Disabling Calibration Security
Before firmware updates can be installed, the counter’s calibration security
feature must be disabled. This done using the command:
CALibration:SECurity:STATe {OFF|ON}, <code>
CALibration:SECurity:STATe? (query form)
To unsecure the instrument, you must provide the security code in addition to
setting the state to
OFF. The security code is set to KT53210A when the instrument
is shipped from the factory. Note, however, the security code may have been
changed once the counter has been in use.
After the firmware update is complete, the counter can be re-secured by setting
the state to
ON and providing the security code. The calibration count is
unaffected when changing the security state or by a firmware update.
The calibration count can be read with the command:
CALibration:COUNt?
