Incoming Inspection
The incoming inspection procedures are optional procedures that check the functionality of the instrument and require
no equipment other than a display. For a more robust inspection, see the performance verification procedures in the
Specifications and Performance Verification manual that is included on the User Documentation CD that was shipped
with your instrument.
BasicTurnOnandSelfTest
1. Connect an XGA monitor to the
instrument.
2. Connect the AC power cord to the rear of
the instrument and to a 100 to 240 VAC
source. There is no power switch on
your instrument: it will turn on as soon
as you apply power.
3. Look at the front panel immediately after
you apply power. All of the buttons, the
text over the three knobs, and the Fault
indicator should light up.

tion
NOTE. After a couple of seconds, the lights
in the buttons and text will turn off. After
about 15 seconds, the fault light should turn
off and the Power On diagnostic page should
appear on the monitor.
4. Verify that the instrument passes all self
tests. Any failures will be shown in Red.
The results of the Power On diagnostics
are erased from the screen, but you
can view them by selecting CONFIG >
Utilities > View Diagnostic Log.
5. After the diagnostics are finished, the
instrument state will be restored. When
the progress indicator in the lower-right
part of the screen is finished, the
instrument has finished initializing.

Using a Web Browser
You can use a Web browser to access the instrument and save screen captures, download presets, and download the error
log. Your instrument does need to be connected to an IP network via Ethernet. You will need to set the IP Config Mode, IP
Address, Subnet Mask, and possibly the Gateway Address, to meet your network configuration requirements.
To connect to the instrument using a Web browser, do the following:
