Appendix D: Waveform Transfer (WFMOutpre and CURVe Query) Examples
XUNIT "Hz"
This value indicates the units of the x-axis of the waveform record. This value is always “Hz”
for RF frequency domain traces. This is query only. (If you would like to determine only this
value, use the WFMOutpre:XUNit? query.)
XINCR 2.0000E+6
This value indicates the 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 WFMOutpre:XINcr?
query.)
XZERO 1.4000E+9
This value indicates the frequency, in hertz, of the
fi
rst data point in the waveform record.
This frequency is relative to the time of the trigger, which is always 0. This XZEro frequency
can be negative. This is query only. (If you would like to determine only this value, use
the WFMOutpre:XZEro? 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
WFMOutpre:PT_Off? query.)
YUNIT "W"
This value indicates the units of data points in the waveform record. This value depends on
the vertical units of the source waveform – in this case, watts. This is query only. (If you
would like to determine only this value, use the WFMOutpre:YUNit? query.)
YMULT 1.5625E-3
This value indicates the multiplying factor to convert the data point values 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 WFMOutpre:YMUlt? query.)
YOFF 0.0E+0
This value indicates the vertical position of the source waveform. This value is unused for
RF frequency domain traces and is always 0.
YZERO 0.0E+0
This value indicates the vertical offset of the source waveform. This value is unused for RF
frequency domain traces and is always 0.
DOMAIN FREQUENCY
This value indicates the domain in which the source waveform is displayed and stored. For
RF time domain traces, the domain is Time and waveform transfer information is treated
as integer information. For RF frequency domain traces, the domain is Frequency and
waveform transfer information is treated as
fl
oating point information. This is query only. (If
you would like to determine only this value, use the WFMOutpre:DOMain? query.)
WFMTYPE RF_FD
This value indicates the type of the source waveform. RF_FD indicates an RF frequency
domain trace (frequency domain waveform). This is query only. (If you would like to
determine only this value, use the WFMOutpre:WFMTYPe? query.)
CENTERFREQUENCY 2.4000E+9
This value indicates the center frequency, in hertz, of the source waveform. This is query only.
(If you would like to determine only this value, use the WFMOutpre:CENTERFREQuency?
query.)
SPAN 2.0000E+9
This value indicates the frequency span, in hertz, of the source waveform. This is query
only. (If you would like to determine only this value, use the WFMOutpre:SPAN? query.)
REFLEVEL 1.0000E-3
This value indicates the reference level, in watts, of the source waveform. This is query only.
(If you would like to determine only this value, use the WFMOutpre:REFLEvel? query.)
