8 :ACQuire Commands
:ACQuire:RSIGnal
(see page 1610)
Command Syntax
:ACQuire:RSIGnal <ref_signal_mode>
<ref_signal_mode> ::= {OFF | OUT | IN}
The :ACQuire:RSIGnal command selects the 10 MHz reference signal mode.
• The OFF mode disables the oscilloscope's 10 MHz REF BNC connector.
• The OUT mode is used to synchronize the timebase of two or more instruments.
• The IN mode is used to supply a sample clock to the oscilloscope. A 10 MHz
square or sine wave signal is input to the BNC connector labeled 10 MHz REF.
The amplitude must be from - 5 dBm to 17 dBm (356 mVpp to 4.48 Vpp).
Query Syntax
:ACQuire:RSIGnal?
The :ACQuire:RSIGnal? query returns the current 10 MHz reference signal mode.
Return Format
<ref_signal_mode><NL>
<ref_signal_mode> ::= {OFF | OUT | IN}

information on using the 10 MHz reference clock.
Do not apply more than 20 dBm Max (6.32 Vpp Max) at the 10 MHz REF BNC
connector on the rear panel or damage to the instrument may occur.
