Making a Measurement
Sampling Measurements
To Set up Sampling Parameters
1. Confirm that
SAMPLING
is set in the MEASUREMENT MODE field on the
CHANNELS: CHANNEL DEFINITION screen. If
SAMPLING
is not set, select
SAMPLING secondary softkey in the MEASUREMENT MODE field.
2. Press Meas key in the PAGE CONTROL key group.
3. Select SAMPLING SETUP primary softkey.
4. In the MODE field of SAMPLING PARAMETER, select:
• LINEAR secondary softkey for equally spaced sampling intervals.
• LOG XX secondary softkey for logarithmically spaced sampling intervals.
XX
is 10, 25, or 50 sampling points per decade.
• THINNED-OUT secondary softkey for reduced sampling interval of more
recent samples (by thinning less recent samples).
For details about sampling mode, see “Sampling Measurement Mode” in
Chapter 2.
5. In the INITIAL INTERVAL field, enter a value for the first sampling interval.
6. In the NO. OF SAMPLES field, enter the number of points at which to sample.
7. If you select LINEAR or THINNED-OUT in MODE field, set the TOTAL
SAMP. TIME (total sampling time) which specifies the time from the start of
sampling to the end. This field is not available for the logarithmic sampling.
In the TOTAL SAMP. TIME field, enter a value or select:
• NO LIMIT secondary softkey for excluding the total sampling time from the
sampling completion conditions.
• AUTO secondary softkey for excluding the total sampling time from the
sampling completion conditions, and including the number of samples to the
completion conditions. This softkey is available only for the linear sampling.
For details about sampling completion conditions, see “To Define Stop
Conditions” on page 4-47.
