26 CBLé System Guidebook
Understanding CBL Commands
(Continued)
Example
Assume the CBL receives two one-parameter commands as successive
lists as shown by the following:
:{1}→→L:Send(L)
:{3}→→L‚:Send(L‚)
The CBL interprets the first list ({1}) as a Channel Setup command and
performs the following default operations:
1. Selects
CH1
to collect data.
2. Uses
AutoIDENT
values if active, and voltage (0 to 5 Volts) if not
active. All other
CMD1
parameters default to 0 and are not active.
As previously noted,
CMD3
must be the last setup command sent to the
CBL before data collection begins.
The CBL interprets the second list ({3}) as a Sample and Trigger Setup
command and performs the following default operations:
1. Sets Sample Time to 0.5 seconds, Number of Samples to 1, Trigger
Type to Manual, and Trigger Channel to 1. All other
CMD3
parameters
default to 0 and are not active. (
READY
is lit in the display.)
2. Collects one sample when N is pressed (the
SAMPLING
indicator blinks, and then
DONE
is lit in the display).
There are many more default parameters than those listed above. The
predefined settings will become more clear as you read about each of
the commands starting on the next page. On the following pages, default
parameters are shown in boldface for each of the command descriptions.
