LAN Reset
The LAN reset button restores the instrument's default LAN configuration.
Instrument State LEDs
When the power is applied to the U3020AS16, the instrument enters its
power-on sequence which requires several seconds to complete. The LEDs
provide information on the state of the instrument during power-on and
upgrades of the instrument firmware. Table
identifies the instrument states
based on the color and functioning of the LEDs.
Standby Switch
Note that this switch is Standby only, not a line switch. The main power cord
can be used as the system disconnecting device. It disconnects the mains
circuits from the mains supply.
Reflection and Transmission Ports
There are two separate signal channels and each channel can have a switch
path to any one of the 16 Test Ports. The two channels, however, cannot
share the same Test Port or you will see a dual LED indication over that Test
Port. For example, the command sequence:
ROUT:SEQ:TRIG rp1;: ROUT:SEQ:TRIG tp1;
would cause this error indication.
To correct this error, you will have to resend the two switch commands with
different test port selections to reset the display and switches.
