- Set Burst Mode Frequency

System
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
