:ACQuire:RSIGnal
(see page 1208 )
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}

C A U T I O N
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.
