Sampling Measurements
Measurement Functions
3. If the sampling completion condition is not satisfied after additional 5 points
measurement, linear sampling mode changes the sampling interval to two times
the previous interval, and continues sampling measurement. Measurement data
is updated as described in step 2.
4. This discarding and doubling of the sampling interval is repeated until the
sampling completion condition is satisfied. By the end of the measurement, 10
measurement result data is stored in memory.
Parameters
To set up the linear sampling measurement, specify the following parameters on
MEASURE: SAMPLING SETUP screen. See Table 3-1.
Parameter Description
MODE Sampling mode. LINEAR.
INITIAL INTERVAL The sampling interval for first NO.OF SAMPLES samples.
Allowable range: 60 μs to 65.535 s.
NO.OF SAMPLES Number of data to be stored by end of measurement.
Maximum: 10001. If there are multiple measurement units,
this value must be 10001/(number of units) or less.
TOTAL SAMP.TIME Total sampling time. Does not include HOLD TIME. This is
the time from the 1st trigger to the sampling completion.
One of the sampling completion conditions, so sampling
stops after this time elapses.
• Allowable range when
INITIAL INTERVAL ≤ 480 μs:
AUTO
• Allowable range when
INITIAL INTERVAL > 480 μs:
INITIAL INTERVAL × (NO.OF SAMPLES − 1) sec to
1 × 10
11
sec, AUTO, or NO LIMIT.
AUTO Enables the number of sampling points sampling
completion condition.
NO LIMIT Disables the total sampling time sampling completion
condition
