Appendix D: Waveform Transfer (WFMOutpre and CURVe Query) Examples
WFMOutpre? Query results
Explanation
NR_PT 25
This value indicates the number of data points in the waveform record to be transferred
using the CURVE? query. (If you would like to determine only this value, use the
query.) Note: this value is typically equal to the full record length,
but you also have the option to transfer only a portion of the record length by using the
and
commands.
PT_FMT Y
This value indicates the format of the data points in the waveform record. In this case, the
value represents YT format. This is query only. (If you would like to determine only this
value, use the
query.)
PT_ORDER LINEAR
This value is always
LINear
.
XUNIT "s"
This value indicates the units of the x-axis of the waveform record. This is determined by
the horizontal settings for the waveform source. Typically, this value is “s”, representing
seconds. When using the math waveform as a source, the value can be “s” or “Hz”. This
is query only. (If you would like to determine only this value, use the
query.)
XINCR 100.0000E-9
This value indicates the time, in seconds, or frequency, in hertz, between data points in the
waveform record. This is query only. (If you would like to determine only this value, use
the
query.)
XZER0 -500.0000E-6
This value indicates the time, in seconds, or frequency, in hertz, of the
fi
rst data point in the
waveform record. This time or frequency is relative to the time of the trigger, which is always
0. So, this XZEro time or frequency can be negative. This is query only. (If you would like to
determine only this value, use the
query.)
PT_OFF 0
This is a query provided only for compatibility with other Tektronix oscilloscopes. The
returned value is always 0. (If you would like to determine only this value, use the
query.)
YUNIT "State"
This value indicates the vertical units of data points in the waveform record. This can be
any of several string values, depending upon the vertical units of the source waveform –
in this case, State. This is query only. (If you would like to determine only this value, use
the
query.)
YMULT 1.0000
This value indicates the multiplying factor to convert the data point values from digitizing
levels to the units speci
fi
ed by the
WFMOUTpre:YUNit
command. This is query only. (If
you would like to determine only this value, use the
query.)
YOFF 0.0E+0
This value indicates the vertical position of the source waveform in digitizing levels. There
are 25 digitizing levels per vertical division. This is query only. (If you would like to determine
only this value, use the
query.)
YZERO 0.0E+0
This value indicates the vertical offset of the source waveform in units speci
fi
ed by the
WFMOUTpre:YUNit
command. This is query only. (If you would like to determine only
this value, use the
query.)
Example 3: Digital with 4 Bytes Per Point and Zoom Off
Goal: Transfer 25 points of Digital data from the oscilloscope to a PC using 4
bytes per point and Zoom off.
