0.3-3 GHz SPECTRUM COMPACT (FW V5.2.6) 

OPERATION 

 

19 

 

 

 

 

 
 

 

SCALE menu is available only for default units “dBm”. Adjust the scale before 
selecting non-default units!

SCALE 

The SCALE menu allows selecting the MAX (highest limit of the vertical axis) and 

MIN (lowest limit of the vertical axis) values of the displayed input power range in 
dBm, and an input power level OFFSET value (e.g. if an external attenuator is being 
used) in decibels dB.  

 

 

SCALE menu is only available for default units “dBm”. See 

UNITS

.

 

 

 

While at the SCALE menu, tapping the upper part of the graph decreases the 
displayed input power range (zooms in) and tapping the lower part of the graph 
increases  the  displayed  input  power  range  (zooms  out).  If  the  input  power 
range allows it, sliding the graph up or down modifies the MAX and MIN values 
by equal amounts.

 

 
The  currently  selected  parameter  (MAX/  MIN/  OFFSET)  is  displayed  in  white.  To 

select a different parameter, tap on it once. The color of the keypad buttons shows 
which numbers can be entered at the current digit position to obtain a valid parameter 
value – the numbers on the 

green

 

buttons can be entered, the numbers on the 

red 

buttons cannot be entered. If the currently entered value is valid, it is displayed in 

The UNITS menu
