Harmonic Analysis Mode - The "Vertical" Menu
Harmonic Analysis Mode (cont'd)
ch1 ch2
ch3 ch4
Modification of the parameters of ch1, ch2, ch3 or ch4 , independently.
Sensitivity/Coupling
Channel Sensitivity
Coupling
Modification of the channel's sensitivity using the stylus on the scrollbar:
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 : the instrument connects the selected channel input to a 0 V ref. level.
The " " symbol indicates the coupling selected. It is shown in the modified
channel parameter display area.
bw limit Bandwidth limit for the channel and its trigger circuit, to reduce display noise and
false triggering.
The bandwidth limit of each channel can be limited to 5 kHz, 1.5 MHz or
20 MHz. The bandwidth limit of a channel is displayed in the control area by the
ollowing symbols : f
This menu can also be called up by double-pointing with the stylus on the
required channel parameter display area (ch1, ch2, ch3 or ch4).
Vertical scale Defines the vertical scale of the selected channel on the basis of the current
settings.
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" area.
The key deletes the character preceding the cursor in this area.
Predefined values (x1, x10, x100, x1000), corresponding to standard probe
coefficients, can be assigned directly.
The sensitivity value indicated in the channel parameters display will be modified
in accordance with the coefficient.
Measurement unit Modification of the selected channel's vertical scale unit.
This modification is performed using the mouse and the table of usable
characters, after selecting the "Measure Unit" zone.
The key can be used to delete the value preceding the cursor in the zone to
be modified.
The vertical scale unit will be indicated in the modified channel's parameter
display.
Init Reinitializes the multiplication coefficient to 1.00 and returns to the V
measurement unit.
This menu can also be called up by double-pointing with the stylus on the
required channel parameter display area (ch1, ch2, ch3 or ch4).
Probix This menu is identical to the one in "Oscilloscope" mode.
With the
Probix HX0030 probe (1/10 probe), some functions are inactive in
"Harmonic Analysis" mode.
