Rear-Panel Connectors
1. Trigger Out. Use the trigger signal output
to synchronize other test equipment
with your oscilloscope. A LOW to HIGH
transition indicates the trigger occurred.
The logic level for Vout (HI) is ≥2.5V open
circuit; ≥1.0 V into a 50Ω load t o ground.
The logic level f or Vout (LO) is ≤0.7 V into
a load of ≤4mA;≤0.25 V into a 50Ω load
to ground.
2. XGA Out.UsetheXGAVideoport(DB-15
female connector) to show the oscilloscope
display on an extern a l monitor or projector.
3. LAN. Use the LAN (Ethernet) port (RJ-45
connector) to connect the oscilloscope to a
10/100 Base-T local area network.
4. Device. Use the U SB 2.0 High speed
device port to control the oscilloscope
through USBTMC or GPIB with a
TEK-USB-488 Adapter. The USBTMC
protocol allows USB devices to
communicate using IEEE488 style
messages. This lets you run your GPIB
software applications on USB hardware.
