Field Description Examples
Source The s ource ide
ntification string as it appears in
the front-panel scale factor readouts.
“CH1–4”
“Math1
“Ref1–4"
Coupling A string describing the vertical coupling of the
waveform (t
he Source1 waveform in the case of
Dual Waveform Math).
“AC coupling”
“DC couplng
”
“GND coupling”
Ve rt Scale A string containing the vertical scale factor of
the unzoomed waveform. T he numeric portion
will alway
s be four digits. The examples cover
all supported units.
“100.0 mV/div”
“20.00 dB/div”
“45.00 deg
/div”
“785.4 mrad/div”
“500.0 μVs/div”
“10.00 kV/
s/div”
“200.0 mV/div”
“50.00 unk/div”
Horiz Scale A string c ontaining the horizontal scale factor of
the unzo
omed waveform. T he numeric portion
will always be four digits. The examples cover
all supported units.
“100 ms/div”
“10.00 k
Hz/div”
Record Length
A string containing the number of waveform
points
available in the entire record. The
numeric portion is given as an integer.
“1000 points”
Acquis
ition Mode
Astrin
g describing the mode used to acquire the
waveform.
“Sample mode”
“Pk Detect mode”
“Enve
lope mode”
“Average mode”
Center Frequency A string containing the center frequency value
of the waveform.
“2.400GHz”
Span A string containing the frequency span value of
the
waveform.
“20.00MHz”
Ref
erence Level
Ast
ring containing the reference level value of
the waveform.
“1.000mW”
Ex
amples
WFMOUTPRE:WFID? might return :WFMOUTPRE:WFID "Ch1, DC
coupling,100.0mvolts/div,500.0µs/div, 1000 points, Sample
mode"
WFMOutpre:WFMTYPe? (Query Only)
This query returns the type of the outgoing waveform. RF_FD indicates an RF
frequency domain waveform; RF_TD indicates an RF time domain waveform;
ANALOG indicates Channel 1–4 or the Math waveform. The default is analog.
For non-MDO models, this query always returns ANALOG.
