34 :TIMebase Commands

:TIMebase:REFClock

(see page 1610)

Command Syntax

:TIMebase:REFClock <value>

<value> ::= {{1 | ON} | {0 | OFF}

The :TIMebase:REFClock command enables or disables the 10 MHz REF BNC

located on the rear panel of the oscilloscope.

The 10 MHz REF BNC can be used as an input for the oscilloscope's reference

clock (instead of the internal 10 MHz reference), or it can be used to output the

internal 10 MHz reference clock when synchronizing multiple instruments (see

":ACQuire:RSIGnal" on page 310).

The :TIMebase:REFClock ON command enables the 10 MHz REF BNC and sets the

reference signal mode to IN. The :TIMebase:REFClock OFF command disables the

10 MHz REF BNC (the same as setting the reference signal mode to OFF).

Query Syntax

:TIMebase:REFClock?

The :TIMebase:REFClock? query returns the current state of the 10 MHz reference

signal mode. A "1" indicates that the 10 MHz REF input is enabled (on), and a "0"

indicates that either the 10 MHz REF BNC is disabled (off) or that it is set as an

output (by the :ACQuire:RSIGnal command).

Return Format

<value> ::= {0 | 1}
