L1
Number of samples to collect. If Statistics is selected in
CMD1
,
the upper limit is 256.
Causes continuous data collection following each
Get(
,
GET
or
Input "CBLGET"
instruction from a calculator. This value is
necessary for real-time data collection.
Note: When Number of Samples is L1 for real-time display of collected
data:
¦ Only one channel can be active.
¦ Post-processing will not operate (pages 29, 31).
¦ Record Time will not operate (page 44).
¦ Filter will not operate (page 46).
Trigger Type
This parameter lets you select a specific point at which to start
collecting data. You can trigger CBL to start collecting data at a specific
point on the actual data, or on an external clock. The function performed
by Trigger Types 2 to 5 depends on whether or not period or frequency is
selected in
CMD1
. (Default:
1
)
0 None.
The following triggering information applies when the Number of
Samples is L1 and Trigger Type is 0:
¦ If Sample Time is less than or equal to 0.20 seconds, then a
sample will be taken immediately after receiving the Sample and
Trigger Setup command (
CMD3
). Subsequent samples will be
taken immediately after a
Get(
or
Input "CBLGET"
instruction is
received from the calculator.
¦ If Sample Time is greater than or equal to 0.25 seconds, then the
first sample will be taken at the sample time after the Sample and
Trigger Setup command is received.

Manual. Lets you manually start data collection by pressing N.
Manual triggering (Trigger Type 1 or 6) is useful when you want to
set up the CBL and then disconnect it from the calculator to collect
the data. The CBL waits for you to press N before starting data
collection.
