Exercise 3. Connecting a Signal
CAUTION Electrostatic discharge (ESD) on or near input connectors can damage circuits
inside the instrument. Repair of damage due to misuse is not covered under
warranty. Before connecting any cable to the electrical input, momentarily
short the center and outer conductors of the cable together. Personnel should
be properly grounded, and should touch the frame of the instrument before
touching any connector. For more information regarding ESD, refer to the
Agilent 83480A, 54750A User’s Guide.
1Using the Agilent 8133A pulse generator (or equivalent), set a trigger and
square wave signal to the following:
Trigger level . . . . . . . . . . . . . . . . . . . . . . . . . . . 200 mV (do not exceed 2 Vp-p)
Pulse level. . . . . . . . . . . . . . . . . . . . . . . . . . . . . 500 mV (do not exceed 2 Vp-p)
Pulse frequency . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 50 MHz
CAUTION Cables can build up high voltage levels that can discharge into the channel or
trigger inputs and cause damage. Cables should be discharged using a short or
a 50Ω terminator prior to connection.
2Make sure the trigger and pulse signals are enabled.
3Connect the trigger to the trigger input (channel 2) on the Agilent 83483A,
54751A electrical plug-in module.
4Connect the pulse signal to the electrical input (channel 1) on the
Agilent 83483A, 54751A electrical plug-in module.
5Display the Setup menu (on the Agilent 83480A, 54750A) and select the
default setup by pressing:
Setup, Default setup
The default setup puts the instrument in a predefin ed operating condition. This
gives you a known starting point for the following exercises. The default condi-
tions are listed in the setup section of the Agilent 83480A, 54750A User’s
Guide.
