Sampling Measurements
Measurement Functions
To use this function, the INITIAL INTERVAL value must be set to 2 ms or more.
The INITIAL INTERVAL is the minimum resolution of the sampling interval. For
details about the INITIAL INTERVAL, see “Linear Sampling Measurement” on
page 3-13, “Thinned-out Sampling Measurement” on page 3-16, or “Logarithmic
Sampling Measurement” on page 3-19.
To set up the stop condition, specify the following parameters on the MEASURE:
SAMPLING SETUP screen.
Parameter Description
ENABLE/
DISABLE Enables or disables the stop condition.
ENABLE DELAY Delay time. in second. This is the time from starting sampling
measurement to enabling this function.
Allowable range: 0 to INITIAL INTERVAL × 32767 s.
Resolution: INITIAL INTERVAL.
NAME Name of measurement data or user function to monitor for stop
condition.
Val of EVENT.
THRESHOLD Threshold value at which to stop sampling measurement.
Th of EVENT.
EVENT Event for stop condition.
Val > Th True if NAME parameter value is greater than
THRESHOLD value.
Val < Th True if NAME parameter value is less than
THRESHOLD value.
|Val| > |Th| True if absolute NAME parameter value is
greater than absolute THRESHOLD value.
|Val| < |Th| True if absolute NAME parameter value is less
than absolute THRESHOLD value.
EVENT NO. Target value of the count the event occurs (true). When the
count of true is this value, sampling is immediately stopped.
Allowable range: 1 to 200.
