2.6 Power Requirements
The model 4033 and 4034 can be operated from any source of 100-240V +/-10% AC, at a frequency from 48Hz to
66Hz. The maximum power consumption is 50 VA.
WARNING
THE LINE POWER VOLTAGE OF THE INSTRUMENT IS NOTED ON THE AC INPUT PLUG. TO
PREVENT DAMAGE TO THE INSTRUMENT, CHECK FOR PROPER MATCH OF LINE VOLTAGE
AND PROPER FUSE TYPE AND RATING.
The instrument power fuse is located in the AC input plug. To access the fuse, first disconnect the power cord and
then remove the fuse cartridge. Use T1A 250V fuse only, as labeled in the rear panel of the unit.
2.7 Grounding Requirements
For the safety of operating personnel, the instrument must be grounded. The central pin on the AC plug grounds the
instrument when properly connected to the ground wire and plugged into proper receptacle. The power jack and the
mating plug of the supplied power cable meet IEC safety standards.
WARNING
TO AVOID PERSONAL INJURY DUE TO SHOCK, THE THIRD WIRE EARTH GROUND MUST BE
CONTINUOUS TO THE POWER OUTLET. BEFORE CONNECTION TO THE POWER OUTLET,
EXAMINE ALL CABLES AND CONNECTIONS BETWEEN THE UNIT AND THE FACILITY POWER
FOR A CONTINUOUS EARTH GROUND PATH.
THE POWER CABLE MUST MEET IEC SAFETY STANDARDS.
2.8 Signal Connections
Use RG58U 50
Ω or equivalent coaxial cables for all input and output signals to and from the instrument. Below
specifies the BNC connectors on the instrument:
OUTPUT – Up to 10 Vpp into 50
Ω impedance (20 Vpp into open circuit). The instrument is protected from short
circuit to ground.
TRIG IN – 10 k
Ω impedance, selectable positive or negative slope, variable level from – 10 V to + 10 V. Input
protected to
±15 V.
SYNC OUT – A positive pulse signal in phase with the main output. TTL levels with a 50
Ω source impedance and
with 3.5 ns typical transition times.
