3 Statistics (mean, standard deviation, minimum, maximum)
Derivative and statistical post-processing are performed using values pro-
duced by conversion equations.
• Post-processing is disabled whenever the number of samples parameter
of Command 3 (SAMPLING/TRIGGER SETUP) is –1, which specifies
real-time display of sampled data.
Stat Samples Parameter
This parameter is used during statistical post-processing to specify how many
samples should be used for post-processing. This parameter is valid only
when 3 (statistics) is specified for the post-processing parameter. A value
from 2 to 512 can be specified for this parameter, and the initial default for
this parameter is 10.
Channel 5 (DIG IN)
The following parameter setting applies only when Channel 5 (DIG IN) is
specified by the Command 1 channel parameter.
Operation Parameter
This parameter applies to digital input only. When 1 (active) is specified for
this parameter, data sampling can be performed from the digital logic circuit.
The initial default for this parameter is 1.
0 Clears the digital input channel.
See “Channel Clear” for details.
1 Active
• See “Clock-In Line Operation” for further technical information about this
parameter.
