Oscilloscope Mode - The "Vertical" Menu
IV - 48 SCOPIX Oscilloscopes
Oscilloscope Mode (cont'd)
Display
Opens the "Trace display" menu for validating or devalidating the traces.
Validation of the selections by " OK ". Exit from the menu without modification
by " Cancel ".
The " " symbol in front of a trace indicates that it has been validated.
The traces can be validated or devalidated from the control area by using the
stylus.
ch1 ch2 ch3 ch4
Modify the parameters of channels ch1, ch2, ch3 and ch4 independently, as
well as the vertical scale of the trace selected.
Sensitivity / Coupling Modifies the parameters of the selected channel.
Channel Sensitivity
Coupling
Modification of the channel's sensitivity using the stylus on the scrollbar,
adjustable by sequence: from 2.5 mV to 200 V/div.
The sensitivity is indicated in the channel parameter display area. It takes into
consideration the parameters of the "Vertical scale" menu.
Modification of AC - DC - GND coupling
AC : blocks the DC component of the input signal and attenuates the
signals below 10 Hz
DC : transmits AC and DC components of the input signal
GND : internally, the instrument links the input of the channel selected to a
0 V reference level.
The " " symbol indicates the coupling selected. Coupling is indicated in the
modified channel's parameter display area.
bw limit Limits the bandwidth of the channel and its trigger circuit to reduce display
noise and false triggering.
The bandwidth of each channel can be limited to 5 kHz, 1.5 MHz or
20 MHz. The bandwidth limit of a channel is indicated in the control area by
following symbols :
This menu can also be called up by double-pointing with the stylus on the
required channel parameter display area.
Vertical scale
Defines the vertical scale of the channel selected on the basis of the current
settings. Readings of the direct measurements of the value analyzed and its
unit are provided.
Coefficient Assignment of a multiplication coefficient to the selected channel's sensitivity.
This can be modified with the stylus, using the table of usable numbers, after
selecting the "Coefficient" zone.
The key deletes the character preceding the cursor in this area.
The predefined values (x1, x10, x100, x1000) correspond to standard probe
coefficients and can be assigned directly.
The sensitivity value indicated in the channel parameter display will be
modified according to this coefficient.
20 MHz 1.5 MHz
5 kHz
