TRIGGER OUTPUT
The female BNC connector can be used to provide a signal to another device. The sig-
nal is TTL compatible (0 V / 5 V). The "Trigger out" softkey in the "In-/Output" menu
(INPUT/OUTPUT key) is used to control the trigger output.
IF/VIDEO
The female BNC connector can be used for various outputs:
●
Intermediate frequency (IF) output of approximately 20 MHz
●
Video output (1V)
The "In-/Output" menu (INPUT/OUTPUT key) is used to select between the IF and
video output.
USB
The rear panel provides two additional female USB connectors to connect devices like
keyboard and mouse. Also, a memory stick can be connected to store and reload
instrument settings and measurement data.

Electromagnetic interference (EMI) can affect the measurement results. To avoid any
impact, make sure that the following conditions are met:
●
Use suitable double-shielded cables.
●
Do not use USB connecting cables exceeding 1 m in length.
●
Use only USB devices that remain within the permissible EMI limits.
●
Always terminate any connected IEC-bus cables with an instrument or controller.
