Getting Started
BNC Connectors
The oscillosco
pe BNC reference connection is made on the inside of the BNC
connector. The black bayonet on the outside of the BNC connectors does not
provide electrical contact. For a good connection, make sure your probe or cable
connector is pushed on and twist locked. Replace cables or probes that have
worn connectors.
Unterminated BNC Inputs
The black bayonet on the outside of the BNC input connectors does not shield
the connector input from unwanted electrical noise from nearby circuits. Connect
a50Ω terminator or a BNC shorting plug to the input BNC connector when
establishing a "No Signal" baseline condition.
Installation
You can use the oscilloscope AC adapter to power the oscilloscope or to charge
battery
packs when installed. To use the oscilloscope AC adapter as the power
source, follow these steps:
1. Insert
the DC connector end of the adapter into the DC INPUT connector on
the back of the oscilloscope.
2. Conne
ct the appropriate power cord between the oscilloscope AC adapter
and an electrical outlet.
If ba
ttery packs are installed, an LED lights on the front of the oscilloscope to
indicate when the battery packs a re charging.
NOTE. The oscilloscope contains a temperature-sensing fan for cooling that
forces air through vents on the bottom and on the side of the oscilloscope. To
allow air to flow freely through the oscilloscope, do not block these vents.
