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 user – see 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.
