9 Default Settings | Power On State | Hard Reset
9.1 Restoring to Factory Defaults
When shipped from the factory, the set-up of the instrument is as described within Appendix B
(section 17). The instrument can be returned to its factory defaults condition from
Setup/Functions > Setups > Load Defaults (see section 4.9.1).
9.2 Standard Preset
The standard preset is accessed by pressing the hard key marked Preset. It returns the
instrument to a set of known conditions as below:
(Note that some parameters are relevant only if option U01 is fitted)
Frequency/Span
(Mode = Centre/Span)
Centre = 1350.5MHz/650.5MHz
Span = 2699MHz/1299MHz
Sweep/Bandwidth
RBW = Auto (1MHz)
Vid Filter = On,
Sweep Control = Repeat
Trigger = Free Run, Auto Rearm
Level/Limits
Ref Level = 0dBm
Units = dBm, Graticule = Normal
Scale = Normal (10db/div)
75Ohm Compensation = Off
Fixed Offset = Off
Compensation Table = Off
Limit 1 = Off, Limit 2 = Off
Traces/Markers
Live Trace = On,
View Trace = Off
Reference Trace = Off
Mode = Normal
Display = Single Trace
Marker 1 = On, Marker 2 = Off
M1 = 1350.5MHz / 650.5MHz
Markers Function = Scroll
M1 Fix = Off
Setup/Functions
Logging = Disabled
Auto Measure = Disabled
Parameters not included within the listing above are left unchanged.
The User Preset is a customisable version of the Standard Preset whereby any of the
parameter values of the standard preset can be changed to match the requirements of the
current usersee section 4.11.1.
9.3 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.
