Acquisition
In Manual mode you can set the Sample
Rate and Record Length. Horizontal Scale
is a dependent variable calculated from the
sample rate and record length.
The Horizontal Scale knob changes record
length in manual mode.
All three modes interact with sample rate,
scale, and record length as shown. The
horizontal line is the maximum real-time
sample rate. Each staircase shows that as
you increase the scale, the sample rate must
decrease when either the maximum record
length or the record length limit you set is
reached. Manual mode uses the maximum
record length.
Automatic and Constant Sample Rate
modes are identical. However, Constant
Sample Rate mode keeps the sample rate
constant at a rate that guarantees bandwidth
enhancement
fi
lters are used.
Quick tips
Digital sample rate and resolution are dependent variables, and are controlled by the analog sample rate selection.
