Chapter 4, Description of Fields

Fields

Time (Configure)

This field sets the time-of-day for the instrument’s 24 hour clock. (Example, 4:53 PM is entered 16:53)

Operating Considerations

The internal clock still functions when the instrument is turned off.

Screens Where Field is Present

CONFIGURE

TimeBase

This field setting determines whether the Test Set uses its internal 10 MHz timebase or attempts to detect an external signal on the EXT REF INPUT connector.

•Auto

•Int

GPIB Example

“DISP CONF;CONFigure:TBASe:MODE ‘Int’“

displays the CONFIGURE screen and selects the internal timebase.

Operating Considerations

When Auto is selected in this field, an indicator below this field will display “External” if a 1, 2, 5, or 10 MHz reference has been detected on the rear panel EXT REF INPUT connector. If no reference signal is present, this indicator will read “Internal”, meaning that the Test Set is currently using its high-stability 10 MHz timebase as a reference signal.

When Int is selected in this field, the Test Set uses its high-stability 10 MHz timebase as a reference signal, and the indicator below this field will display “Internal”.

NOTE:The Test Set does not require a cable or any other type of jumper between the 10 MHz

OUTPUT and EXT REF INPUT in order to use its internal timebase.
