CT-BOX Viewer – Quick Start Guide

CHANNEL SETTINGS 

The software treats every CT-BOX as a single channel of a conventional oscilloscope. 
From the channel menu, the user can 

show/hide

 a channel, change the multiplication 

scaling  factor  (

Scale

,  expressed  in  [1/A])  and  the 

Offset

.  Furthermore,  the  user  can 

enable the 

normalization of the signal

 (every channel is scaled w.r.t. its maximum of 

the absolute value of the acquired window) and eventually 

remove its DC

 value (again 

calculated considering the samples of the window).  

 
COMMON AND TRIGGER SETTINGS 

Once  the  trigger  is  enabled  (see 

Figure  12

),  the  user  can  add  (i)  the  trigger 

Source

 

choosing among the added CT-BOX, (ii) the trigger 

Edge

 (positive, negative or both), 

(iii)  the  trigger 

Level

  (expressed  in  [A])  and  (iv)  its 

Position

  on  the  time  axes 

(expressed in [sec]).  
Concerning the time axes, the acquisition 

Window

 (expressed in [s]) can be changed 

in the Common options section. In the same section, the user can find the RUN/STOP 
indication  (to  easily  understand  the  status  of  the  current  acquisition)  and  the  trigger 

MODE

, that can be: 

 

NORMAL, it plots the signal any time the trigger condition is met, otherwise 
it does not update the waveform; 

 

AUTO,  it  automatically  sets  a  trigger  configuration  in  order  to  meet  the 
condition; 

 

SINGLE,  it  plots  the  signal  only  the  first  time the  trigger  condition  is  met, 
then it stops the window updating; 

 

STOP, it forces the stop of the window updating. 

 
KIND SETTINS 

In  the  Kind  Settings  section,  the  user  can  choose  the  type  of  the  waveform  among 

TRACES

  (the  current  as  a  function  of  time)  or  its 

FFT

  (Magnitude  or  Phase)  as  a 

function of the frequency.
