15-8 Peak hold
The PEAK HOLD facility is used to build up an image of band
activity over a period of time, the display is not totally cleared each
time a trace is made, only strong signals are added.
To toggle PEAK HOLD on/off
, the "HLD" legend confirms when peak hold is active.
The
keys may be used to move the marker position and
key may be held to monitor
activity on the marker frequency.
15-9 Saving active trace to memory
To save the current trace to internal memory (for later retrieval)
. It is suggested that the peak hold facility
be employed before saving a trace so that it provides more
meaningful information.
If the optional EM8200 is used, it possible to save four further
traces to external memory. Refer to section 18-7-7 of this manual
for further information regarding this feature.
15-10 Loading stored band scope traces from memory
Providing a trace has been previously stored to memory, it is possible to recall it to display using the key
sequence
. The legend "RCV" (in the place of "MKR") indicates
that a stored trace is currently being displayed.
The AR8600 will no longer sweep the frequency range but the
key may still be used to monitor
the marker frequency. Key in a new centre frequency to return to a real time band scope.
It is possible to move the marker across the graphical trace using the
keys. Waveform enlarge-
ment is available by changing the frequency sweep width using the
keys.
If the optional EM8200 is used, it possible to load any one of four
further traces from external memory. Refer to section 18-7-7 of
this manual for further information regarding this feature.
It is also possible to connect the AR8600 to an external Spectrum
Display Unit, the AOR SDU5500 has been designed specifically
for this purpose. Please refer to section 1-7 of this operating
manual. The 10.7MHz i.f. output BNC socket on the rear of the
AR8600 will need to be activated in a workshop prior to operation
with the SDU5500.
