ACQuire:SAMPlingmode
Description
This command sets or queries the sampling mode.
Group
Acquisition
Syntax 1
ACQuire:SAMPlingmode{RT|IT|ET}
Syntax 2
ACQuire:SAMPlingmode?
Arguments
H RT
This argument sets the sampling mode to real time only.
H IT
This argument sets the sampling mode to interpolation allowed.
H ET
This argument sets the sampling mode to equivalent time allowed.
The number of channels selected and the sampling speed affects the
mode that the instrument uses to acquire data. At slow sampling speeds
the instrument uses real time sampling. At fast sampling speeds, the
instrument uses equivalent time sampling or interpolation. For speeds
between these extremes, the instrument creates waveform records dif-
ferently, depending on the number of input channels selected. Refer to
the following table, which assumes 500--point records when indicatimg
the mode.
