8.4 Unrecoverable Fault Condition - Hard Reset
If the spectrum analyzer gets into a condition in which normal operation is not possible, it can
be returned to normal operation by reloading the Factory Default settings - see section 4.9.1.
However, if it “locks up” (i.e. will not respond to key presses)
or cannot be recovered by using Load Defaults, it can be put
through a Hard Reset.
The reset button is accessed through a small hole at the top
right hand side of the case. It can be operated using the
stylus (or other thin rigid object). Press and hold for longer
than 1 second.
Hard Reset will re-load the operating system, return all
parameters to their factory defaults, and clear all of the non-
volatile buffers. User data and settings that have been saved as files will not be affected.
9 Firmware Updates | Upgrades | Maintenance
9.1 Updating the Firmware
From time to time TTi may make updated versions of the instrument firmware available in order
to add new features or to correct “bugs”. These will be downloadable from the Aim-TTi website
without charge. The current version is displayed within the Status display screens.
The method of updating requires the use of a USB Flash drive. Full information on how to
perform the update will be provided with the firmware file.
9.2 Upgrading the Firmware (Option U01)
Installing option U01 is done in a similar way to a firmware update, but an additional step of
entering an activation code will be needed (see section 6). Full details are provided with the
option.
9.3 Maintenance, Re-calibration & Cleaning
To ensure that the accuracy of the instrument remains within specification, the calibration
should be checked (and if necessary adjusted) annually. Aim-TTi or their agents overseas will
provide a calibration service for any PSA1302/2702 and will repair any PSA developing a fault.
Where owners wish to undertake their own recalibration, this should only be done by skilled
personnel in conjunction with the Service Guide which may be obtained directly from Aim-TTi or
their agents overseas. Recalibration requires the use of a precision signal generator as
specified in the Service Guide
Cleaning: If the unit requires cleaning, use a cloth that is only lightly dampened with water or a
mild detergent. Take particular care in cleaning the touch screen area.
