Key Features
This chapter will help you set up and begin to use the WFM8200 and WFM8300
Waveform Monitors. It is divided into the following four sections:
Key Features describes your instrument and provides a list of key features.
Accessories shows you how to verify that you have received all of the parts of
your instrument and provides a list of standard and optional accessories and a
list of options that are available for your instrument.
Network Installation shows you how to set up your instrument on an
Ethernet network.
Incoming Inspection provides a procedure for verifying the basic operation
and functionality of your instrument.
The WFM8200 and WFM8300 Waveform Monitors are baseband monitors

monitoring and measuring features across a broad range of signal formats,
including 3 Gb/s, Dual Link, SD, HD, and composite.
This instrument is a reference measurement tool that can be used in the design
and manufacture of production equipment. It provides the precision and intuitive
monitoring capabilities necessary to standardize and maintain a signal through
the distribution system to the viewer.
Your instrument provides comprehensive support for physical layer measurements
d newer high definition digital production formats. It can provide a warning
an
of any deviation from accepted standards or possible signal incompatibilities,
and allows you to immediately evaluate the effect of any adjustment. The key
features of your instrument make it an easy to use, flexible, and effective tool.

FlexVu™ display
CaptureVu™ The CaptureVu™ capability allows capture of a full frame of video
The FlexVu™ display is a four-tiled, high-resolution XGA display
that provides four concurrent views of a monitored signal. The
instrument also provides the flexibil ity to configure each of the
four display tiles independently, enabling you to quickly check the
integrity of a signal. In SIM mode, the FlexVu™ display allows for
the monitoring of two signals at the same time, dividing the display
into two sides; one for each signal.

user-selectable gamut thresholds so that you can set monitoring
limits appropriate to a specific operation. Gamut monitoring is fully
integrated with the alarm logging and reporting capabilities. This
display type allows you to use the Multi-Input Display feature.
Longitudinal Time Code (LTC) is monitored in a frame rate display
to allow observation of amplitude, synchronization and phase with
respect to reference vertical interval time code (VITC).

Installation
See the WFM8200 and WFM8300 Safety and Installation Instructions that
shipped with your instrument for basic installation instructions.
If you are installing this instrument into a system, see the WFM8200 and
WFM8300 System Integration Technical Reference for detailed installation
instructions.
After your instrument is physically installed, you might want to connect it directly
to a PC and a network. The following information can help you do that.
Connecting Directly to a
PC
The following procedure will help you connect your instrument to a PC:
1. Connect the instrument directly to a PC with an Ethernet cable. The instrument
has an auto-crossover feature. You can also use a HUB. (See Figure 1.)
2. Set up the instrument as described in the following procedures, 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.
Figure 1: Connecting the instrument to a PC
8 WFM8200 and WFM8300 Waveform Monitors
Getting Started
Connecting to a Network
The following t
opics 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 network access to the instrument, you
must set the IP a ddress. Network addresses can be assigned either automatically
(DHCP) or ma
nually. 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:
1. Press CONFIG to display the Configuration menu.
2. Select N
etwork Settings > Web Enable.PressSEL to select On.
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
eters in this menu; see your LAN administrator for required values. (Be
param
sure to use compatible addresses between the PC and the instrument.) You
can also set the instrument name and view the MAC Address.
SNMP Setup
5. Press CONFIG to close the Configuration menu.
If you intend to use SNMP commands to control the instrument (SNMP control
rimarily intended for access through automation systems), you must set up
is p
SNMP parameters.
NOTE. The WFM8200 and WFM8300 Waveform Monitors wfm_mon.mib and the
wfm8000.mib contain SNMP OIDs and can be downloaded from the instrument
Web page. You can also download a printable version of a MIB manual from
www.tektronix.com/manuals.
The procedure to set SNMP settings is similar to the procedure for IP settings.
(See page 9, Connection and IP settings.)
This table shows the parameters that you can set.

the performance verification procedures in the WFM8200 and WFM8300
Specifications and Performance Verification Technical Reference that is included
on the Product Documentation CD that shipped with your instrument.
You can perform the following test with or without the external monitor. Using
the external monitor allows you to check that the DVI connector on the rear panel
is working properly:
1. Connect a monitor to the EXT DISPLAY connector on the rear panel of the
instrument. This connector is a DVI-I connector with socket contacts. The
output supports DVI monitors directly and analog PC (RGB) monitors using a
DVI-I to VGA adapter.
2. Connect the AC line cord to the rear of the instrument and to a 100 to
240 VAC source.

Simultaneous Input Monitoring
Your instrument can monitor two separate signals simultaneously. In this mode,
the instrument display is divided into two sides, each with two tiles per input.
This allows you to c onveniently view measurement and status displays from
two signals at the same time. You can monitor the following combinations:
DI + SDI, and SDI + CMPST.

When viewing 525-line SDI input as a composite waveform while using line select
