●
USER CONTROL is a D-sub connector used as an input and output for low-voltage
(3.3 V) TTL control signals.
●
EXT. TRIGGER is an input for a low-voltage (3.3 V) TTL external trigger signal.
Input levels, EMC
The maximum input levels and voltages of the input connectors at the front and rear
panel must not be exceeded.
The EXT TRIGGER input connector and pin 2 of the USER CONTROL connector must
never be used simultaneously as inputs for external trigger signals.
Use double shielded cables at the BNC rear panel connectors (10 MHz REF, PORT
BIAS, EXT. TRIGGER) and match signals with 50 Ω in order to comply with EMC
directives!
1.3 Putting the Analyzer into Operation
This section describes the basic steps to be taken when setting up the analyzer for the
first time.
Risk of injury and instrument damage
The instrument must be used in an appropriate manner to prevent electric shock, fire,
personal injury, or damage.
●
Do not open the instrument casing.
●
Read and observe the "Basic Safety Instructions" at the beginning of this manual or
on the documentation CD-ROM, in addition to the safety instructions in the follow-
