Measure Commands 24
Agilent Infiniium 90000 Series Oscilloscopes Programmer's Reference 541
:MEASure:NOISe:SCOPe:RN
Command
:MEASure:NOISe:SCOPe:RN {ON, <RNrms Zero>, <RNrms One> | OFF}
The :MEASure:NOISe:SCOPe:RN command can specify the removal of the
oscilloscope's calibrated random noise from the reported RN.
• ON — Enables the removal of the oscilloscope's calibrated random noise
from the reported RN.
• <RNrms Zero> — The oscilloscope's "zeros" random noise to remove from
the reported RN.
• <RNrms One> — The oscilloscope's "ones" random noise to remove from
the reported RN.
• OFF — Disables the removal of the oscilloscope's calibrated random
noise from the reported RN.
Running the Calibrate scope jitter / noise from the front panel user interface
will set <RNrms Zero> and <RNrms One> to the measured values; however,
the measures values can be changed by this command.
Example This example specifies 100 &#956;V of oscilloscope "zeros" random noise
and 200 &#956;V of oscilloscope "ones" random noise.
myScope.WriteString ":MEAS:NOISE:SCOPE:RN ON, 100e-6, 200e-6"
Query :MEASure:NOISe:SCOPe:RN?
The :MEASure:NOISe:SCOPe:RN? query returns the oscilloscope RN
settings.
Returned Format
[:MEASure:NOISe:SCOPe:RN] {ON, <RNrms Zero>, <RNrms One> | OFF}<NL>
Example This example places the oscilloscope RN settings in the
strScopeRandomNoise variable and displays it on the computer's screen.
myScope.WriteString ":SYSTem:HEADer OFF" ' Response headers off.
myScope.WriteString ":MEASure:NOISe:SCOPe:RN?"
strScopeRandomNoise = myScope.ReadString
Debug.Print strScopeRandomNoise
NOTE
This command is only available when the EZJIT Complete software is installed.
