Connecting the CMU to the Test Setup
Warning:
Connect external devices and peripherals only when the instrument is
switched off or in STANDBY mode. Otherwise, future errors cannot be
excluded.
Connecting a Controller
The CMU can be connected to an external controller via the GPIB bus (IEEE bus according to standard
IEEE 488; throughout this documentation we will primarily use the term GPIB bus which is also used in
the operating menus and in the SCPI command syntax) or via serial interface:
Connection via GPIB
bus
IEEE 488
625
The CMU is connected to the GPIB interface of the controller via the GPIB
bus connector (IEEE 488 / IEC 625) at the rear of the instrument and a
shielded cable. The technical specifications of the GPIB interface are listed in
section "Hardware Interfaces " in Chapter 8.

Configuration
The parameters for GPIB bus control of the CMU are set in the Remote tab
of the Setup popup menu (in the following abbreviated by Setup – Remote,
see also chapter 4, Settings for Remote Control).
! To open the Setup - Remote menu, press the SETUP key at the front of
the instrument and activate the Remote hotkey at the lower edge of the
screen.
! Use the rotary knob to move the focus onto the SCPI Connection section
of the Setup table. If necessary, press the rotary knob or the ON/OFF
key to expand the parameters in the table (see Chapter 3).
! In the Port table row select the GPIB bus interface for transmission.
The bus address is factory-set to 20. It can be changed in the Primary
Address input field.
