Software Setup
General
Depending on your application, you will need to set several software parameters. Proper settings will
allow WaveView to organize data to meet your requirements. Some items of importance to the WBK18 are
the low-pass and high-pass filter options that can be selected from the WaveView Configuration main
window and the excitation source and overrange detection parameters that can be chosen from the
Module Configuration window. The Module Configuration window can be accessed from the View pull-
down menu or by use of the first toolbar button (located just below the File pull-down menu).
Reference Note:
For detailed WaveView information, refer to the
WaveView Document Module
.
WaveView Configuration Window
In the WaveView Configuration main window (see figure) the following columns are applicable to the WBK18.
LPF Mode – Click on a cell in the LPF Mode column to make the cell active, and then change its setting. Options
for WBK18’s LPF Mode are:
(a) 8-Pole: selects the 8-pole low-pass filter
(b) 2-Pole: selects the 2-pole low-pass filter
(c) Bypass – bypasses the low-pass filter
LPF Cutoff - Click on a cell in the LPF Cutoff column to make the cell active, and then change its setting. Options
for LPF Cutoff (in Hz) are: 10, 20, 50, 100, 200, 500, 1000, 2000, 5000, 10000, 20000, and 50000. Note that when
the LPF Mode is “Bypass,” this parameter is fixed at 200000 Hz.
Reference Note:
Application information regarding the proper setting of LPF Mode and LPF Cutoff is provided in the
sections entitled
Maximizing Alias Protection
Using the 2-Pole Filter and Bypass
HPF Cutoff - This is used to select input coupling. Click on a cell in the HPF Cutoff column to make the cell
active, and then change its setting. Options for HPF Cutoff are:
(a) 0.1 Hz: selects the 0.1 Hz, 1-pole high-pass filter
(b) 10 Hz: selects the 10 Hz, 2-pole high-pass filter
(c) DC: selects DC coupling
Note that when the Range is “
±25V,” the HPF Cutoff is fixed at DC.
Range - This is used to select the input range. Click on a cell in the Range column to make the cell active, and
then change its setting. Options for Range are:
±25V, ±5V, ±2.5V, ±1V, ±500mV, ±250mV, ±100mV, ±50mV,
and
±25mV. Note that when the Range is “±25V,” the HPF Cutoff is fixed at DC.
