Measure Commands 24
Agilent Infiniium 90000 Series Oscilloscopes Programmer's Reference 537
:MEASure:NOISe:ALL?
Query
:MEASure:NOISe:ALL? {ZERO | ONE}
The :MEASure:NOISe:ALL? query returns the NOISe measurement results
for the specified level. These values are returned as comma separated
values using the following format:
Returned Format
[:MEASure:NOISe:ALL<space>]
TI(<format>),<result>,<state>,
RN(<format>),<result>,<state>,
DI(<format>),<result>,<state>,
PI(<format>),<result>,<state>,
PI(<format>),<result>,<state>,
ISI(<format>),<result>,<state>,
Count,<number_of_bits>,<state>,
Level,<nominal_level>,<state><NL>
<space> White space (ASCII 32) character.
<format> The format value tells you something about how the measurement is made.
For instance, TI(1E- 12) means that the TI measurement was derived using
a bit error rate of 1E- 12. A format of (rms) means the measurement is a
root-mean- square measurement. A format of (d- d) means the
measurement uses a dual- Dirac delta model to derive the measurement. A
format of (p- p) means the measurement is a peak- to- peak measurement.
<result> The measured results for the NOISe measurements. A value of 9.99999E+37
means that the oscilloscope was unable to make the measurement.
<state> The measurement result state. See Table 23 for a list of values and
descriptions of the result state value.
<number_of_
bits>
The number of waveform bits that have been measured.
<nominal_level> The Level line returns the nominal one or zero level. The unit amplitude =
the nominal one level – nominal zero level.
Example This example places the noise measurement result for "ones" in the
strResults variable and displays it on the computer's screen.
Dim strResult As String ' Dimension variable.
myScope.WriteString ":SYSTem:HEADer OFF" ' Response headers off.
myScope.WriteString ":MEASURE:NOISe:ALL? ONE"
strResults = myScope.ReadString
Debug.Print strResults
