●
AUX is an auxiliary connector, to be wired as needed. AUX is not fitted on standard
instruments.
●
LAN 1 and LAN 2 are two equivalent connectors to connect the analyzer to a Local
Area Network.
●
USB is a double Universal Serial Bus connector of type A (master USB), used to
connect a keyboard, mouse or other pointing device.
●
DC MEAS comprises two inputs for DC measurements, specified for different voltage
ranges.
●
10 MHz REF serves as an input or output for the 10 MHz reference clock signal.
●
MONITOR is a sub-Min-D connector used to connect an external VGA monitor.
●
CASCADE is a 8-pin RJ-45 connector used as output and input connectors for pulse
generator signals. The CASCADE connector is located between the MONITOR and
the USER CONTROL connectors.
●
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.
Shock hazard
Do not open the instrument casing. As a rule, normal operation of the instrument does
not require opening the casing. Observe the general safety instructions and regulations
at the beginning of the manual.
