1 SPG-1801 Sync Pulse Generator Module
1.1 Introduction
The SPG-1801 is a sync pulse generator that can be slotted in the Densité frame. It accepts an external
reference input or can receive its reference from the frame reference internal distribution, if the REF-1801
card is present. It offers 2 full flexible outputs, individually configurable for format but also for timing
adjustment. The SPG-1801 can lock on a composite (NTSC/PAL) or tri-level sync. The signal output can be
video (black burst, tri-level sync) or audio (word clock, DARS). In the case of an audio output, the SPG-1801
can also lock on an external DARS or Word Clock.
It is ideal for generating multi-format synchronization signals that can be used in certain areas of a broadcast
or production facility. The fact that it can be slotted in a Densité chassis coupled to the frame distribution card
(REF-1801) makes it a highly-integrated solution for multi sync generation and distribution.
1.2 Features
•Can be slotted in Densité frames
•Accepts either an external genlock input or an internal sync signal from the frame reference card
•fully configurable outputs
•Can generate composite black burst, tri-level sync, DARS or Word Clock
•Up to 1 frame adjustable timing for each individual output

3 Operation
3.1 Control Options
The SPG-1801 has two primary control interfaces:
•The local control panel attached to the Densité frame’s controller
•Remote control using Miranda’s iControl system
These will be explained in detail in the following sections.
3.2 Local control using the Densité frame control panel
Push the SELECT button on the SPG-1801 card edge (see Section 1.4) to assign the local control panel to
operate the SPG-1801. Use the control panel buttons to navigate through the menu, as described below.
All of the cards installed in a Densité frame are connected to the frame’s controller card, which handles all
interaction between the cards and the outside world. There are no operating controls located on the cards
themselves. The controller supports remote operation via its Ethernet ports, and local operation using its
integrated control panel.
The local control panel is fastened to the controller
card by a hinged connector, and when installed is
located in the front center of the frame, positioned in
front of the power supplies. The panel consists of a
display unit capable of displaying two lines of text,
each 16 characters in length, and five pushbuttons.
The panel is assigned to operate any card in the frame
by pushing the SELECT button on the front edge of
that card. Pushing the CONTROLLER button on the
control panel selects the Controller card itself. The
STATUS LED on the selected card flashes yellow.
The local control panel displays a menu that can be navigated using the four pushbuttons located beneath
the display. The functionality of the pushbuttons is as follows:
[CTRL] Selects the controller card for status monitoring and adjustment
[+] [–] Used for menu navigation and value modification
[SELECT] Gives access to the next menu level. When a parameter value is shown, pushing this button
once enables modification of the value using the [+] and [–] buttons; a second push confirms the
new value
[ESC] Cancels the effect of parameter value changes that have not been confirmed; pushing [ESC]
causes the parameter to revert to its former value.
Pushing [ESC] moves the user back up to the previous menu level. At the main menu, [ESC]
does not exit the menu system. To exit, re-push the [SELECT] button for the card being
controlled.
If no controls are operated for 30 seconds, the controller reverts to its normal standby status, and the
selected card’s STATUS LED reverts to its normal operating mode.

Clicking this button will reset all SPG-1801 parameters to factory-default values, overriding settings
made in the control panels.
3.3.2 Input tab
Reference Source
The pulldown selects the reference source for this SPG-1801. The
choices are:
•Auto – Use the external reference, URS or the internal
reference (in order of priority).
•External – use the reference connected to the rear panel
•URS – use the Universal Reference Signal generated by an
REF-1801 card located in slot 10 of the Densité frame
•Internal – use the internal reference source
Time Code
The Timecode Source pulldown selects the source of timecode that
will be inserted in the outgoing reference signals from this SPG-
1801. The choices are:
•Auto – Use LTC if available, if not, then VITC and lastly URS
timecode.
•VITC – extract timecode from the reference input Figure 3.2 Input tab

GUIDE TO INSTALLATION AND OPERATION
12 | SPG-1801
•LTC – use the timecode connected to the LTC input on the rear panel
•TC (URS) – use the timecode included in the URS signal. generated by an REF-1801 card located in
slot 10 of the Densité frame
The current status of time code available at the SPG-1801 input is shown in the LTC Status, VITC Status
and TC (URS) Status areas
•Valid (green icon): valid time code detected at the input
•Phase error (red icon):
SMPTE-12 specifies the phase relation between LTC and video. If the LTC received does not match
this alignment window, the card will flag this error.
•Frame error (red icon):
The time code must match the input reference frame rate. If not, an error is flagged.
•Absent (red icon): no time code detected at the input
Note: The error detection algorithm uses the current reference format. So, when using internal reference, all
information extracted from the input is out of phase, and the card may flag errors even if the timecode is
nominally OK.
3.3.3 Output tab
The Output tab provides resources to configure the output sync
signals.
•Each of the two sync outputs can be configured independently.
Format – the pulldown selects the format of the sync output. Available
choices are:
•Black Burst 59.94
•Black Burst 50
•Tri-Level 1080i59.94
•Tri-Level 1080i50
•Tri-Level 720p59.94
•Tri-Level 720p50
•DARS 48 kHz
•Word Clock 48 kHz
Note that not all of these output choices will be available at all times.
The output formats available depend on the format of the reference
input.
•The following chart shows the relationship between reference
input format and available output formats.

Overall Alarm is shown in the upper left corner of the iControl panel, and also appears at the bottom of the
Status/Name column.
•GSM Contribution
This column allows configuration of the
contribution of each individual alarm to the
GSM Alarm Status associated with this card.
GSM is a dynamic register of all iControl
system alarms, and is also an alarm provider
for external applications. The possible
values for this contribution are related to the
Overall alarm contribution:
•If the Overall alarm contribution is
selected as Disabled, the GSM alarm
contribution can be set to any available
value
•If the Overall alarm contribution is
selected as any level other than
disabled, the GSM contribution is forced to follow the Overall Alarm.
Levels associated with these alarms:
The pulldown lists may contain some or all of the following options:
The alarm makes no contribution (black icon)
The alarm is of minor importance (yellow icon)
The alarm is of major importance (orange icon)
The alarm is of critical importance (red icon)
The alarm exists but has no effect (used for text and composite alarms)
Shortcut: if you click in one of the columns beside SPG-1801 in the Status/Name column (where there is
no pulldown shown), you will open an “invisible” pulldown that lets you assign a level to all alarms in that
column simultaneously.
