Overview Control elements and resources To define a spectral math waveform
Set the time
domain
controls
22. The Time domain controls determine the sample rate
and record length of the acquisition. These controls
allow you to change the duration on the acquisition
without changing the sample rate.
From the Spectral Analysis Setup menu, click
Resolution and adjust the time interval between data
samples of the input waveform.
Note : Resolution is the inverse of Sample rate. Adjust
resolution to adjust sample rate. Resolution may also
cause a change in record length such that the duration
is kept constant at the value selected by the Duration
control.
23. To adjust the number of seconds over the duration of the
acquired waveform (record length), click Duration and
use the multipurpose knobs or pop-up keypad to adjust
the duration.
Note: Changing duration also changes the record
length.
24. Gate position is the position of the phase reference point
in the gate with respect to the trigger in seconds. The
gate position and gate duration must be within the
acquisition.
To set the gate position, click Gate Pos, and use the
multipurpose knobs or pop-up keypad to adjust the gate
position.
25. Gate duration and resolution bandwidth are the same.
Gate duration is displayed in seconds and resolution
bandwidth in hertz.
To set the gate duration, click Gate Dur, and use the
multipurpose knobs or pop-up keypad to adjust the gate
duration.
