9910DA-AV-EQ Functional Description

Figure 1-1 shows a functional block diagram of the 9910DA-AV-EQ. With
the appropriate rear modul e, th e 9910DA- AV-EQ can provide up to eight DA
analog video outputs and a looping input where desired.

9910DA-AV -EQ Input/Output Formats

The 9910DA-AV-EQ provides the following inputs and outputs:

• Inputs:

• ANALOG VIDEO IN – coaxial analog composite video input

• Outputs:

• ANALOG OUT (1-8) – up to eight analog composite outputs

• LOOP OUT – where enabled using card j umper and with appropriate

rear module, the card provides a hi -Z (untermin ated) loope d output
of the input

Input Differential/Single-Ended Select

Using an on-card jumper, the 9910DA-AV-EQ can float the input shield
connection from ground, and use both the + and shield connections as a
differential pair, thereby providing much improved common-mode noise
rejection that minimizes the effects of ground-loop noise and other issues. A
single-ended jumper position provides normal operation where the shield
connection is tied to chassis ground. (Default position is typical single-ended
operation with shield lead tied to chassis GND.)

Input Loop/Termination Select

Using an on -card jumper, the 991 0DA-AV-EQ can terminate the input into a
Z

= 75Ω or offer a hi-Z input with the input available as a looped output.

o

(Default position is 75Ω terminated position with no looping output.)

Input AC/DC Coupling Select

Using an on-card jumper, the 9910DA-AV-EQ can use input capacitive
coupling or full DC coupling to the card active circuitry. Low-frequency
cut-off of the singl e coupli ng capacit or is su ch that n ormal vide o bandwidth is
not affected. Wher e AC coupling is used, the Video Clamp feature of this card
should also be used to restore correct DC levels with APL (active picture
level) changes. (Default position is DC-coupled.)

Input Status Display

Via DashBoard or similar compatible remote control/monitoring, the card
shows input signal presence and video format (e.g., 525i, 720p, 1080i) of the
received input signal. Signals that are not a recognized video format (e.g.,
DARS or AES) show presence but may be reported as “unknown”.

the EQ adjustment stage such that gain adjustment and EQ optimization have
no effect on each other’s optimized settings and are independent. Regardless
of most distribution purposes, gain adjustment (if necessary) should provide

Modules (p. 2-6) for more information.

Input AC/DC
Coupling Select

Sets the signal coupling at the first active device in the card as
capacitively coupled or full (input-to-output) DC coupled.

The AC-coupled position can restore expected ground-level blanking on
sources where the blanking interval may not be at GND potential.

Note: • Card has two AC/DC jumpers. Both must be set to AC or DC for

proper operation.

• Clamping should also be used if AC coupling is used.

Video Clamping
Select

Sets clamping on or off. Clamping can help eliminate hum on the output
signal in cases where poor grounding or other signal routing issues are
present on the input.

When set to on, slow and fast clamping can also be selected using
another jumper. Slow clamping is stable, while fast clamping is optimized
to respond to fast changes in APL where required.

Clamping is intended for use only with SD black-burst (bi-level) sync
signals and may result in loss of output if used with HD tri-level input
signals. If inputs other than SD black burst may be present, do not
enable clamping. Clamping is not required for any input condition where
excessive hum or grounding issues are not present.

1. Determine the slot in which the 9910DA-AV-EQ is to be installed.

2. Open the frame front access panel.

3. While holding the card by the card edges, align the card such that the

plastic ejector tab is on the bottom.

4. Align the card with the top and bottom guides of the slot in which the

card is being installed.

5. Gradually slide the card into the slot. When resistance is noticed, gently

continue pushing the card until its rear printed circuit edge terminals
engage fully into the rear I/O module mating connector.

CAUTION

If card resists fully engaging in rear I/O module mating connector, check for
alignment and proper insertion in slot tracks. Damage to card and/or rear I/O
module may occur if improper card insertion is attempted.

flat surface of the card. These can be observed
looking across the card top surface. These indicators
should be lit when the card is in a powered frame.

GAIN control provides a ± 3.0 dB relative gain
trim of the outputs. This baseline gain
adjustment is valid across the passband
(including theoretical base DC gain
independent of any EQ peaking).
(Default position is centered to provide unity
gain.)

Ideally, adjust gain for 100 IRE at destination.
(See below) EQ control provides peaking of the

card high-frequency response to compensate
for cable reactive losses. As the EQ control is
rotated cw, HF boost is added.
(Default position is null; full ccw.)

The EQ level function is analogous to peaking
of an oscilloscope probe calibration. Multi-burst
or modulated T/2T signals allow viewing the
transient response (time domain) of the sync
edge and the frequency response flatness out
to 4.5 - 5 MHz. Any test signal will work if only
concerned about adjusting for a clean (not
rounded) transition on the sync edge (viewed at
the destination). The adjustment should be
optimized for the distribution purpose (i.e. if ref
sync is distributed, optimize the EQ for the sync
edge, if video is distributed for a monitor or
source feed, optimized the EQ for the frequency
response).

Note: Full range of this control results in stable
(no poles) operation regardless of EQ or gain
settings.

Troubleshooting

Basic Troubleshooting Checks

Failures of a general nature (affecting many cards and/or functions
simultaneously), or gross inoperability errors are best addressed first by
performing basic checks before proceeding further. Table 3-1 provides basic
system checks that typically locate the source of most general problems. If
required and applicable, perform further troubleshooting in accordance with
the other troubleshooting tables in this section.

Check status indicators and
displays

• On both the frame Network Controller Card and the 9910DA-AV-EQ, in all
cases when power is being properly supplied there is always at least one
indicator illuminated. Any card showing no illuminated indicators should be
cause for concern.

• Check the Power Consumed indication for the 9910DA-AV-EQ card. This
can be observed using the DashBoard™ Card Info pane.

• If display shows no power being consumed, either the frame power
supply, connections, or the 9910DA-AV-EQ card itself is defective.

• If display shows excessive power being consumed (see Technical
Specifications (p. 1-7) in Chapter 1, “Introduction”), the 9910DA-AV-EQ
card may be defective.

Make certain all cable connections are fully secure (including coaxial cable
attachment to cable ferrules on BNC connectors). Also, make certain all
connecting points are as intended. Make certain the selected connecting
points correlate to the intended card inputs and/or outputs. Cabling mistakes
are especially easy to make when working with large I/O modules.

assure proper seating by ejecting the card and reseating it again.)
On both DashBoard™ and the 9910DA-AV-EQ card edge indicators, red

indications signify an error condition. If a status indicator signifies an error,
proceed to the following tables in this section for further action.

Check jumper settings Refer to Chapter 2, Setup and Installation. Make certain jumpers are set as

appropriate for type of signal and use the card is carrying.

Clamping is intended for use only with SD black-burst (bi-level) sync signals and may

result in loss of output if used with HD tri-level input signals. If inputs other than SD
black burst may be present, do not enable clamping. Clamping is not required for any
input condition where excessive hum or grounding issues are not present.
