A 4-byte integer, indicating the number of waveform buffers
required to read the data.
A 4-byte integer, indicating the number of waveform points in
the data.
A 4-byte integer, indicating the number of hits at each time
interval during waveform recording when using a certain
sample mode (e.g. Average) to create the waveforms. For
example, when averaging, a count of 4 indicates that each
waveform data point in the waveform recording has been
averaged at least 4 times. The default value is 0.
A 4-byte float, indicating the X-axis duration of the waveform
that is displayed. For time-domain waveforms, it indicates the
duration of time across the display. If the value is zero, then no
data has been acquired.
An 8-byte double, indicating the X-axis value at the left edge
of the screen. For time-domain waveforms, it indicates the
time at the start of the display. The value is treated as a
double precision 64-bit float point number. If the value is zero,
then no data has been acquired.
An 8-byte double, indicating the duration between data
points on the X axis. For time-domain waveforms, it indicates
the time between points. If the value is zero, then no data has
been acquired.
An 8-byte double, indicating the X-axis value of the first data
point in the data recording. For time-domain waveforms, it
indicates the time of the first point. The value is treated as a
double precision 64-bit float point number. If the value is zero,
then no data has been acquired.
- A 4-byte integer, indicating the unit of measurement for X
values in the acquired data.
- 0 = Unknown
- 1 = Volts (V)
- 2 = Seconds (s)
- 3 = Constant
- 4 Amps (A)
- 5 = dB
- 6 = Hz
