Risk of instrument damage
Do not overload the RF input. For maximum allowed values, see the data
sheet.
For AC-coupling, a DC input voltage of 50
V must never be exceeded. For
DC-coupling, DC voltage must not be applied at the input. In both cases,
noncompliance will destroy the input mixers.
When measuring unknown signals, do not use a 0
dB attenuation level.
Otherwise, the input mixer may be damaged or destroyed.
When measuring unknown signals on the second RF input, turn on the
pulse limiter feature. Otherwise, the input mixer may be damaged or
destroyed in case of high power signals.

Trigger Input and Output
The female BNC connector labeled "Trigger Input" allows you to receive an exter-
nal trigger signal.
The female BNC connector labeled "Trigger Input / Output" allows you to receive
an external trigger signal or send a trigger signal to another device.
When you are using the connector as a trigger input, you can apply voltages in
the range from 0.5
V to 3.5
V (the default value is 1.4
V). The typical input impe-
dance is 10
k
Ω
.
When you are using the connector as a trigger output, the TTL compatible signal
is transmitted (0
V / 5
V).
Note that you can find another connector for trigger input and output on the rear
panel.
For more information about controlling and configuring trigger input and output,
refer to the User Manual.

Navigation Control
Navigation control consists of a rotary knob and cursor keys. These keys allow
you to navigate within the display or within dialog boxes.
