<QString> comp
rises t he following comma-separated fields documented in the
following tables:
Table 2-21: Waveform Suffixes
Field Description Examples
Source The source identification string as it appears in
the front panel scale factor readouts.
“CH1–4”
“Math1–3
“Ref1–4"
Coupling A string describing the vertical coupling of the
waveform (the Source1 waveform in the case of
Dual Waveform Math).
“AC coupling”
“DC coupling”
“GND coupling”
Vert Scale A string containing the vertical scale factor of
the unzoomed waveform. The numeric portion
will always be four digits. The examples cover
all known internal 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 containing the horizontal scale factor of
the unzoomed waveform. The numeric portion
will always be four digits. The examples cover
all known internal units.
“100 ms/div”
“10.00 kHz/div”
“50.00 c/div”
Record Length
A string c ontaining the number of waveform
points available in the entire record. The
numeric portion is given as an integer.
“500 points”
“500000 points”
Acquisition Mode A string describing the mode used to acquire
the waveform.
“Sample mode”
“Pk Detect mode”
“Hi Res mode”
“Envelope mode”
“Average mode”
Examples
WFMOUTPRE:WFID? might return :WFMOUTPRE:WFID "Ch1, DC
coupling,100.0mVolts/div,5 00.0µs/div,500 points, Hi Res
mode"
.
WFMOutpre:XINcr? (Query Only)
This query-only command returns the horizontal point spacing in units of
WFMOutpre:XUNit for the waveform specified by the DATa:SOUrce command.
This value corresponds to the sampling interval.
An error is reported if the DATa:SOUrce waveform does not exist.
