Incoming Inspection
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.
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.
Waveform Rasterizers Technical Reference 1

Incoming Inspection
Front Panel Test
1. Press FACTORY to restore the factory
preset. Wait for the progress indicator to
show the process is complete.
2. Press FULL to make the active tile be
full screen.
3. Press HELP to display the help screen.
4. Press all the other buttons.
Each button should flash as you press
it. Most buttons bring up related help
text. Some buttons, such as the presets,
bring up the same information. The
HELP button, the four arrow keys, and
the SEL button do not bring up help text
because they traverse the help panes
and content.
5. Press the right arrow key until the Help
Contents pane in the upper-left corner is
highlighted.
6. Turn the GENERAL knob and verify that
the selector box moves up and down the
list.
7. Press HELP to exit help.
2Waveform Rasterizers Technical Reference

Incoming Inspection
XGA and Extended Diagnostics Test
NOTE. Where the following procedure says to press an arrow key, you can use the general knob on the front panel,
if you prefer.
1. Press the CONFIG button to display the
configuration menu.
2. Select Utilities and then press SEL.
3. Select CPU Color Palette Check
and verify that 16 distinct colors are
displayed. This tests the XGA data path
from the CPU.
4. Use the down arrow key to navigate to
Run Advanced Diagnostics and then
press SEL.
5. When the dialog box appears, use the
right arrow key to highlight the Continue
box and then press SEL to run the test.
6. Verify that the XGA DAC is working by
looking at the White and Red ramps at
the top of the screen, and at the Green
and Blue ramps at the bottom of the
screen. They should not have steps but
should show a smooth transition from
dark to light.
Waveform Rasterizers Technical Reference 3

Incoming Inspection
7. Verify that the frequencies shown are
within 10 kHz, and that rates shown are
within 0.1 μs, of the nominal values listed
to the right.
8. Verify that the bus bit activity tests
(labeled Channel A:, Processor Video:,
and Composite Video:, and appearing at
the bottom of the screen) are as follows:
All three tests show both a red and a
green bar in each bit location.
The Processors Video test shows
8bitsfromthe CPU, a space, then
Hsync, a space, Vsync, a space, and
then the blank line. It is normal for
the Vsync bit to blink occasionally.
9. Press SEL or cycle the power to reboot
the unit for normal operation.
QDR Clock = 25.174 MHz
VGA clock = 64.480 MHz
Audio PLL1 = 12.288 MHz
Audio PLL2 = 12.288 MHz
Hsync rate : Width = 0.9 μs
Vsync PW: Width = 62.5 μs
Fan Test
If the fault light in the lower left corner of the front panel is not on (Red), the fans are running. You should also be able to hear
them and feel air coming out the back of the instrument. At low temperatures, the fans will turn slowly and be very quiet.

Installation Variations
Installation Variations
See the Quick Start User Manual that was shipped with your instrument for basic installation instructions. Read the following
information for other installation situations and for remote communication instructions, an optional procedure that is suitable
for incoming inspection of this product.
Connecting Directly to a PC
The following procedure will help you connect your instrument to a PC:
1. Connect the instrument to a PC through
an ethernet hub, as shown. A standard
crossover cable can be substituted for
the hub.
2. Set up the instrument as described in
the following procedures (See page 6,
Connecting to a Network.), choosing
Manual IP mode to set the IP address
manually. Be sure to set an address that
is compatible with the setting of your PC.
3. If you are using an SNMP setup, use the
SNMP setup procedure.
Waveform Rasterizers Technical Reference 5

Installation Variations
Connecting to a Network
The following topics cover configuring the IP settings, so that you can use your instrument over a network, and configuring
SNMP, which is required if you are using commands to control the instrument.
Connection and IP Settings
To allow ne twork access to the instrument, you need to set the IP address. Network addresses can be assigned either
automatically or manually. If your network does not use DHCP, you will have to manually enter the address for the instrument.
To get an address, talk to your LAN administrator.
To connect your instrument to a network and
access it with a remote PC, do the following:
NOTE. To connect directly between your PC
and the instrument, see Connecting Directly
to a PC.
1. Press CONFIG to display the
Configuration menu.
2. Select Network Settings >Web Enable.
Press SEL to select On.
6Waveform Rasterizers Technical Reference

Installation Variations
3. Set the IP Config Mode to Manual or
DHCP, depending on your network setup.
4. If you cannot use DHCP, set the subnet
mask and gateway address network
parameters in this menu; see your
LAN administrator for required values.
(Besuretous
e compatible addresses
between the PC and the instrument.)
You can also set the instrument name
and view the MAC Address.
5. If the password is set, note it. You will
be prompted for it when you connect to
the instrument.
NOTE. For help with entering or changing
the password, select Web Password, and
press the HELP button.
6. Press CONFIG to close the Configuration
menu.
Waveform Rasterizers Technical Reference 7

Installation Variations
SNMP Setup
If you intend to use SNMP commands to control the instrument (SNMP control is primarily intended for access through
automation systems), you need to set up SNMP parameters.
NOTE. The WFM, WVR, and AMM Series Waveform Monitors wfm_mon.mib and the WVR7120.mib can be downloaded
from the instrument Web page.
The procedure to set SNMP settings is similar to that shown on page 2 for IP settings; the parameters that can be set follow:
SNMP Enable This entry in the Network Settings portion of the Configuration menu allows you to
turn on or off the remote access through SNMP.
SNMP Trap Enable This menu entry allows you to turn on or off the traps that are sent out through SNMP.
SNMP Trap Address This menu entry allows you to set IP addresses to which SNMP traps are sent through
SNMP. Traps can be sent to up to four addresses when error conditions are detected.
NOTE. A value of all zeroes for the address will disable that trap output.
Private Community String This menu entry allows you to set the Private Community string. This string is
effectively a password. Without this string, SNMP commands cannot change values
in the instrument.
NOTE. The Private String is necessary for SNMP access to write changes into
the instrument.
Public Community String This menu entry allows you to set the Public Community string. This string is
effectively a password. Without this string, SNMP commands cannot read values
from the instrument.
NOTE. The Public String is necessary for SNMP access to read values from the
instrument.
Remote Communication
The following topics cover remote communications that occur:
Over an Ethernet network through a Web browser
Over an Ethernet network through a Java applet
Over a cable using the optional remote front panel
