35.1. PRESENTATION
The oscilloscope can be remotely programmed with a computer, from simple standardized commands and using the optical inter-
face USB-RS.
The programming instructions comply with standard IEEE488.2, and the SCPI protocol (Standard Commands for Programmable
Instruments).
This remote programming enables :
„ Instrument configuration
„ Measurement campaigns and their repatriation
„ File transfer (traces, configuration, hardcopy ...)
35.2. CONNECTION OF THE INSTRUMENT
The dialogue between the instrument and the PC can be realized via the optical USB link through the HX0056-Z cable.
„ Connect the USB side of the cable to one of the PC USB inputs.
„ If necessary, install the USB driver supplied with the cord.
„ The PC's operating system creates a virtual communication port COMi (with 'i ' number depending on your computer).
„ Configure the PC port created on the PC to the same parameters as those of the oscilloscope.

35.3.1. TREE STRUCTURE
„ The Command SCPI structure is a tree structure
„ Each command must be ended by a <NL> or <;> terminator character.
„ The command used after the <;> character must be in the same directory as the precedent command, otherwise it must be
preceded by the <:> character and its full name.
Example :
DISP:TRAC:STAT1 1<NL>
DISP:TRAC:STAT2 1<NL>
same as :
DISP:TRAC:STAT1 1;STAT2 1<NL>
same as :
DISP:TRAC:STAT1 1;: DISP:TRAC:STAT2 1<NL>
