Bin
This icon begins a conversion cycle based on
the selection of MC, LP, and RC. Depending
on the status of these bits, the software will in-
struct the converter to do single conversions or
collect data in the FIFO, and display the infor-
mation on the screen. Pressing the STOP but-
ton will end the conversion cycle. All other
icons are disabled during the conversion cycles
to avoid hardware conflicts.
Displays the x-axis value of the cursor on the
Histogram.
Cancel
Once selected, it allows a user to exit from the
COLLECT algorithm. If data conversion sam-
ple sets larger than 64 are being collected and
the CANCEL button is selected, it is recom-
mended that the user reset the evaluation board.
The board will eventually recover from the
continuous collection mode, but the recovery
time could be as long as 10 minutes.

MC/LP/RC Selection
This box allows the user to select between the
different types of conversion cycles available
by modifying the MC, LP, and RC bits in the
configuration

Channel
Initiates the data conversion collection process.
COLLECT has two modes of operation: collect
from file or collect from converter. To collect
from a file an appropriate file from the SETUP-
DISK menu bar option must be selected. Once
a file is selected, its content is displayed in the
graph. If the user is collecting real-time conver-
sions to analyze, the appropriate COM port
must be selected. The user is then free to collect
the preset number of conversions (preset by the
CONFIG pop-up menu discussed below). No-
tice, there is a significant acquisition time dif-
ference between the two methods.
Selects the Setup that will be accessed for sin-
gle conversions (MC = 0). For MC = 1, this
box is ignored.
Data FIFO Boxes
These boxes display the information returned
from the data FIFO buffer when MC = 1. For
MC = 0, the single conversion will be displayed
in box number 1.
•
Channel Data Boxes
When using the CS5521/23, these boxes will
contain the conversion channel information re-
turned with the data word. When using the
CS5522/24/28, these boxes will be inactive.
•
Config
Opens a pop-up panel to configure how much
data is to be collected, and how to process the
data once it is collected. The following are con-
trols and indicators associated with the CON-
FIG panel.
2.6 Histogram Window Overview
The following is a description of the controls and in-
dicators associated with the Histogram Window
(Figure 11). Many of the control icons are usable
from the Histogram Window, the Frequency Do-
main Window, and the Time Domain Window. For
brevity, they are only described in this section.
