11 Calibration Commands
:CALibrate:OUTPut
Command :CALibrate:OUTPut {AC | TRIGOUT | DC,<dc_value>}
The :CALibrate:OUTPut command sets the coupling frequency, trigger
output pulse, and dc level of the calibrator waveform output through the
front-panel Aux Out connector:
• AC — sets the Aux Out to be the probe compensation square wave
(approximately 750 Hz).
• TRIGOUT — outputs a pulse when the trigger event occurs. Use this to
trigger other instruments.
• DC,<dc_value> — a DC level value in volts. The <dc_value> is a real
number from -2.4 V to +2.4 V dc.
Example This example puts a DC voltage of 2.0 volts on the oscilloscope front- panel
Aux Out connector.
myScope.WriteString ":CALibrate:OUTPut DC,2.0"
Query :CALibrate:OUTPut?
The :CALibrate:OUTPut? query returns the current setup.
Returned Format
[:CALibrate:OUTPut] {AC | TRIGOUT | DC,<dc_value> | ZERO | ONE | DPULse
| SOSC | HFOSC}
Example This example places the current selection for the DC calibration to be
printed in the string variable, strSelection, then prints the contents of the
variable to the computer's screen.
Dim strSelection As String 'Dimension variable
myScope.WriteString ":CALibrate:OUTPut?"
strSelection = myScope.ReadString
Debug.Print strSelection
