Sample Period Field
Any time the Time and Voltage Markers field are both Off, the sample period
of the acquired waveform is displayed in the bottom row of the menu fields.
Sample period is the time period between acquired sample points and is the
inverse of sample rate (digitizing rate). Sample period is a function of sweep
speed and can only be changed by changing the s/Div field. Sample period
and sample rates, as they compare with sweep speed, are shown in the
Sample Period tables on page 4-10 and 4-12.
There are two fields to the right of the Sample Period field which pertain to
the sample rate. These fields are the Data acquired at field and the Next
acquisition field.
Data acquired at Field
When acquisitions are stopped, the Data acquired at field shows the sample
rate at which the last acquisition was taken. When the s/Div field is
light-blue, you can turn the knob to change the time base setting.
During a repetitive run, the Data acquired at field and the Next acquisition
field will display the same value on the first acquisition following a s/Div
setting change. This happens because the hardware is reprogrammed
between acquisitions in response to the new time base setting.
Next acquisition Field
When you change the time base setting (see above paragraph), the value in
the Next acquisition field changes to reflect the sample rate at which the
next acquisition will be taken if the Run field is touched.
During a repetitive run, the Data acquired at field and the Next acquisition
field will display the same value on the first acquisition following a s/Div
setting change. This happens because the hardware is reprogrammed
between acquisitions in response to the new time base setting.
