894 Agilent Infiniium 9000 Series Oscilloscopes Programmer's Reference
32 Time Base Commands
:TIMebase:REFClock
Command :TIMebase:REFClock {{ON | 1} | {OFF | 0}}
The :TIMebase:REFClock command enables or disables the 10 MHz REF IN
BNC input located on the rear panel of the oscilloscope. The 10 MHz
reference input is used as a reference clock for the oscilloscope for the
horizontal scale section instead of the internal 10 MHz reference when this
feature is enabled.
Example This example turns on the 10 MHz reference mode.
myScope.WriteString ":TIMEBASE:REFCLOCK ON"
Query :TIMebase:REFClock?
The :TIMebase:REFClock? query returns the current state of the 10 MHz
reference mode control.
Returned Format
[TIMEBASE:REFCLOCK] {1 | 0}<NL>
Example This example places the current value of the 10 MHz reference mode
control in the variable, varSetting, then prints the contents of the variable
to the computer's screen.
myScope.WriteString ":SYSTEM:HEADER OFF" ' Response headers off.
myScope.WriteString ":TIMEBASE:REFCLOCK?"
varSetting = myScope.ReadNumber
Debug.Print FormatNumber(varSetting, 0)
