Safety Information
General Safety Summary
Read the following precautions carefully to avoid any personal injuries, or damage to
the instrument or products connected to it. Use the instrument only as specied.
Use only the power cord supplied for the instrument.
Ground the instrument. The instrument is grounded through the ground conductor of
the power cord. To avoid electric shock, always connect to grounded outlets. Make sure
the instrument is grounded correctly before connecting its input or output terminals.
Connect the signal wire correctly. To avoid damage, observe input polarity and
maximum voltage/current ratings at all times.
Observe all terminal ratings and signson the instrument to avoid re or electric shock.
Before connecting to the instrument, read the manual to understand the input/output
ratings.
Do not operate with suspected failures. If you suspect that the instrument is damaged,
contact the Teledyne LeCroy service department immediately.
Do not operate in wet/damp conditions.
Do not operate in an explosive atmosphere.
Keep the surface of the instrument clean and dry.
Avoid touching exposed circuits or wires. Do not touch exposed contacts or
components when the power is on.
Do not operate without covers. Do not operate the instrument with covers or panels
removed.
Use only the fuse specied for the instrument.
Use proper over voltage protection.
Use anti-static protection. Operate in an anti-static protected area. Ground
measurement cable conductors before connecting to the instrument to discharge any
static electricity before connecting the cables to the instrument.
Observe ventilation requirements. Ensure good ventilation. Check the vent and fan
regularly to prevent overheating.

1. Handle
Pull up the handle vertically for easy carrying of the instrument. When you do not need the handle,
press it down.
2. USB Device Interface
The analyzer can serve as a “slave” device to connect external USB devices. Through this interface, a
PC can be connected to control the analyzer.
3. LAN Interface
Through this interface, the analyzer can be connected to your local network (LAN) for remote control.
4. REF IN 10 MHz
The analyzer can use the internal or an external reference source.
When a 10 MHz external clock signal is received through the [10 MHz IN] connector, this signal is
used as the external reference source and “Ext Ref” is displayed in the status bar of the user
interface. When the external reference is lost or not connected, the instrument switches to its
internal reference source automatically and “Ext Ref” on the screen disappears.
The [10 MHz IN] and [10 MHz OUT] connectors are usually used to build synchronization among
multiple instruments.
5. REF OUT 10 MHz
The analyzer can use the internal or an external reference source.

T3VNA User Manual 11
When an internal reference source is used, the [10 MHz OUT] connector can output a 10 MHz
clock signal generated by the analyzer. This signal can be used to synchronize other instruments.
The [10 MHz OUT] and [10 MHz IN] connectors are usually used to build synchronization among
multiple instruments.
6. Trigger in
In external trigger mode, the analyzer will update the trace scan after the Trigger In connector receives
an external trigger signal that meets the trigger input specifications.
7. Security Lock Hole
If needed, you can use a security lock(purchased separately) to lock the analyzer to a desired location.
8. AC Power Supply
The analyzer accepts 100-240V, 50/60 or 100-120VA 400Hz power supply. Please use the power cord
provided as accessories to connect the instrument.
9. Fuse
Before power on, make sure the analyzer is protected by the proper input fuse.
