EXECUTION
Deferred
SYNTAX
F#freq
Select burst mode sampling frequency where
freq
is a real number and
where
38.5
<
freq
<
20000.0
Hertz (default).
DESCRIPTION
The Set Burst Mode Frequency (
F#
) command is used to select the channel sampling frequency when in the
High-speed, single-channel mode (burst mode).
See
Measuring Modes
section of
Appendix D
for more
information.
For AC measurements where the RMS value is to be returned via the
U16
command, it is the user’s
responsibility to program a frequency which will yield a sufficient whole even number of samples per line cycle in
order to compute the RMS accurately. In general for AC measurements, the frequency should equal (2n * 60) Hz
where n is a positive integer.
EXAMPLE
PRINT#1, “F#15000.0X”
‘ Select 15 KHz sampling frequency
PRINT#1, “F#100.5X”
‘ Select 100.5 Hz sampling frequency
