OPERATING INSTRUCTIONS
INTRODUCTION
The 318/338 is a menu-driven system. This means that all operations are set up by means of menus displayed on the
monitor screen. Refer to the 318/338 Logic Analyzer Operator’s Manual for additional information on the general operation
and characteristics of the 318/338 menus.
INSTALLATION
Installation consists of selecting the appropriate operating voltage, connecting the 318/338 to a power input source, and
connecting the probe(s), as required, to the 318/338 and the circuit under test.
POWER REQUIREMENTS
The 318/338 operates from a nominal 115 or 230 V, 48 to 440 Hz, single-phase power input source. Before connecting
the instrument to a power source, verify that the line-voltage indicator on the back of the instrument is displaying the
correct nominal voltage for the power input source to be used.
CAUTION
Before applying power to the instrument make sure the line- voltage indicator
shows the correct voltage for the power input source being used. The instrument
can be damaged if the line-voltage switch is in the wrong position for the voltage
being supplied. Adjust the red voltage selector switch on the back-end panel of
the instrument for the proper line-voltage. Make sure you are using the correct
power supply cord when connecting the 318/338. If you are unsure if either the
voltage selector switch is in the proper position, or if you have the appropriate
power cord, refer the instrument to qualified service personnel.
POWER CORD
This equipment has a 3-wire power cord with a 3-contact plug for connection to the power source and to protective ground.
The plug protective-ground contact connects (through the power cord protective-grounding conductor) to the accessible
metal parts of the equipment. For electrical shock protection, insert this plug into a power input source socket that has a
securely grounded protective-ground contact. The power cord is detachable. When not in use, it should be stored in the
accessory pouch. Instruments are usually factory equipped with a 115 V power cord unless otherwise ordered. For more
information on power cords, contact your Tektronix representative or your local Tektronix Field Office.
WARNING
Hazardous voltages may be present on the exposed mental surfaces of the
mainframe if the power source socket’s protective ground connection is not
securely grounded.
