The “nominal” transmit level is affected by the 4-pair Coupler in Figure 2.1 as described in Section 2.1. When

Transmit Level

is set to

Max

, the output level is increased by about 1 dB from that nominal level and when set to

Min

, it is reduced by about 1 dB (

see Section 2.2.11 for further detail

). Transmit Level configuration changes are only

applied when the

Apply Level

button is pressed.

Besides

Automatic

and

Nominal

Transmit Slew

may be configured to

Fast

and

Slow

Nominal

would generally

represent an edge transition of 4 nsec per 0.8V transition, or a slew rate of 0.2V/nsec. The

Fast

slew setting would

result in an edge transition of ~3 nsec per 0.8V, or 0.27V/nsec slew rate, while the

Slow

slew setting will configure

edge transition to approximately 4.5 nsec per 0.8V, or a .18V/nsec slew rate. Transmit Slew configuration changes are
only applied when the

Apply Slew

button is pressed.

Configuration Replication

Five of the tabbed menus in PVA Interactive support various forms of resource configuration and therefore include a
capability to copy, or replicate, resource configurations to other test ports. Those menus are

Port Config

Link

Config

Link Monitor

Meters

, and

Packets

. Each of these menus includes a

Copy Settings

button that will open the

dialog shown in Figure 3.13. In the

Port Config

and

Link Config

tab menus, the settings to be copied will be the

selected subset of all configurations controlled by those
menus.

This dialog indicates the current

Copy from

port, that is, the

port from which settings are to be copied. The menu also
includes enabled checkboxes for every other available PVA
test port in the currently connected instrument. To copy
settings to particular PVA test ports, the slot-port check boxes
for those ports are selected and the

DONE

button in pressed.

Configuration settings can be copied from the current test port
to all other PVA test ports simply by selecting the

ALL

PORT

S checkbox and pressing

DONE

. If no destination ports are selected, then no configuration settings will be

copied when the menu is closed.

Finally, it should be noted that if

Copy Settings

is selected before a particular setting has been applied (e.g. an

Apply

Settings

button is annunciating a pending setting change or a meter measurement is not yet initiated after selecting a

meter configuration), that generally the

Copy Settings

button will first apply pending settings to the current test port

prior to copying those test port settings to other test ports.

3.8.

Link Configuration Menu

The remaining tab menus in PVA Interactive all perform operations that involve the TEST PHY. Therefore, they are
only relevant when the TEST
PHY is connected to the

TEST

interface via the

Port

Connection

in the Port Config

menu.

Link Configuration (

Link

Config

) is the second tab menu

within the PVA Interactive
Main Menu (see Figure 3.14).
This menu provides control of
Ethernet link modes, access to
test signals, and control of the
TEST PHY receiver. It
consists of five sub-menus:



Link Config



Gigabit Config



Test Signal



Test PHY


