4 INSTALLATION

4.1 RACK MOUNTING

When mounting the PULSAR units, use 19 inch racks, preferably those with a dept h of at least 70 cm. The units should be mounted adequately, so as to secure optimal operat ion and reliability of your unit. Use sliders compatible with the 19 inch racks used to support the P

When m ounti ng more t han one unit , we advi se you to leav e a space of at l east one uni t in between. These spaces can be covered af terwards with v entil ation prof iles. Mount ing other unit s together with

ULSAR obvi ousl y r equires the air flow to be able to reach all units.

the P Additi onal component s, such as combiners and netstrips are pref erabl e to be mount ed at the back of

the racks, so that t he free air flow between the sides of the unit and the rack is not r estr icted. At the bott om and the t op of t he rack, v entil ation pr ofi les should be m ounted so as to allow the fr esh

air to enter and the hot air t o leav e the rack. I t is of great import ance to pl ace the racks in a condi-

tioned room with a constant temperature of about 25 °C.

ULSAR properly.

When m ount i ng f i v e or m ore uni ts on top of one anot her , the use of f ans i s nec essary. T he power of the fan depends on the number of unit s mounted. For a rack c ontaini ng 15 units with a f ree space of one unit between the units, an ai rflow of 300 m³/hour is requi red. Mounting the f ans requires taking into account that the air should blow alongside t he units and that it can enter the rack through the lower ventilation profiles.

4.2 POWER CONNECTION

Before any other connection is made, the unit must be connected to a prot ec ted earth terminal in both of the following ways (EMC requirements):

- Via the protected earth terminal.

- Via the t hr ee- wir e power cable.

WARNING

Before connecting the unit to the mains of the building installation, the proper functioning of the protecti ve earth lead of the building installation needs to be verif ied.

Check if your AC power source voltage cor responds to the appropri ate power input vol tage for the apparatus. This voltage is noted on the rear side.

Failur e to ground the unit proper ly can result in per sonal injury. Do not defeat the earth-grounding protection by using an extension cable, power cable or autotransformer without a protective ground conductor.

To change the m ains fuse, disconnect the power cable. Pull up the cap and r eplace the fuse by a new one.

WARNING

The use of repai r ed ( jumpered) fuses and/or the short circuiting of the fuse holders is prohibited.

Correct use of connectors

Make sure that all connections to t he PULSAR are secure and that all cabl es are f ree of abrasi ons, tear and cuts. Also m ake sure that no strai n is put on any of the cabl es t hat m i ght cause connect ion problems.

The F-type c onnectors on the rear panel of the m odulator should onl y accept a coax ial cable cent er conductor between 0.56 mm and 1.19 mm in diameter. Coaxial cable center conductor larger or smaller than these diameters should not be used. If used, it may result in dam age or loss of signal at the F-type c onnec tor.

Due to the f act that the larger diam eter cent er conduct or (e. g. gr eater t han 1.19 mm ) will spread the contacts of an F-type connect or further apart, once a larger diameter is inserted into a F-t ype connector, a smal ler diam eter center conductor should not be used i n its place. I f used, it may resul t in loss of signal at the F-type connec tor.

This feature is ver y useful to align the PULSAR in the headend af ter combining all m odulated signals to be sent on the network. Use measurement equipment e.g. a spectr um analyser to check the slope of the

ULAR’s RF output after being combined with all t he other channels. It is possible that the sl ope of t he RF

P spektrum is not flat anymore because of f.i . network charact eristics. T his can be compensated by t ilti ng up or down the slope of the P

Next to the control bar, the state of the slope is shown:

CLAMPING

The vi deo clamper is used to hold the blanki ng lev el c onstant, regardl ess of the changes i n the av erage picture l evel . Two dif ferent m ethods of cl amping ar e selectable: back porch or sync t ip cl amping. Back porch clamping is used in most cases and is based upon the sample & hold principle. It is especially used when hum rejection is wanted. If the video signal becomes too noisy or when specific types of scrambled v i deo signals are used, back porch clamping is no longer possibl e. T he solut ion i s the sync t ip (peak) clampi ng method which is based on a simple peak det ecti on system which i s a slow system. Use sync tip cl amping in case of a too noisy video signal or some specific types of scrambl ed video signals.

VAGC

The video AGC can be white referred or sync ref erred. The selectable AGC mode depends upon the clamping mode:

CLAMPING = B-PORCH: vi deo AGC: OFF

1 DESCRIPTION

The Audio / Video Auxiliary Input for automatic fall-back switching enables the switching between

main and aux iliary baseband input signals. W ith the f ront panel on “ AUTO” the ci rcuit will check the presence of sync pulses in the main v i deo signal . If t hese are not availabl e t he unit will switch -after a short selectable delay- to the auxiliary standby signal. This f eature i s remotel y contr ollabl e by m eans of a hard cont act on the rear panel (see 3.3.2. 2 Stat us and Control) or by t he RS-485 connector and the ROSA software.

OPTION: MAIN SCRAMBLED/AUX UNSCRAMBLED SUBSTI TUTION

ORDER NUMBER: C9825565

1 DESCRIPTION

A PULSAR equipped with this option is able to work with specifi ed (see warning) scrambled v ideo on the mai n (scrambled) input. An unscrambled signal will be placed on the aux input. If the detector does not find any signal at the m ain input , the P able delay- to the unscrambled signal at the aux input. T he audio signal will be switched also. It is also remotely controllable by means of a hard contact at t he r ear panel or by the RS-485 connector.

There are some condi tions that must be f ul fi lled before t his main scram bled/aux unscrambl ed option can be used:

•

The scrambl ed si gnal must be well clamped in the scrambler it sel f: no DC-level variation in time

or temperature. However, if there would be a constant DC-shift in the video, it can be compensated by setting the DC- offset.

•

Hum is not allowed. This can be prevented by using double screened c oaxial cables, as short as

possible e.g. i nstall the m odulator and the scrambler next to eac h other.

ULSAR will switch automatically -after a short select-

T he scrambled signal is connected now to the main input. In thi s case, there is a diff erent signal connec ted to the mai n ( S CR) and the aux (UNSCR) i nput. The signal on the aux can be e.g. a test pat tern.

Updating the software is only necessary if the index of the software i nstalled is of a l ower version than the newly deliv ered soft ware. The index of the sof t ware is indi cat ed on the l abel stuck on t he EPRO M

or GAL. On the label one can find “/ XX”. This number indicates the software versi on.

Observe P r ec autions for Handl ing Electrostat ic Sensitive Devices. Electrostati c discharge (ESD) can damage the electr onic components. Therefor e it is required to work in a static-safe work station.

For the loc ation of t he IC’s, use the internal layout diagram .

•

Replace EPROM U65 with the one include in the kitbox. Only needed when the index of the

EPROM in the kitbox is higher than the one that is installed.

•

1 DESCRIPTION

If t his option is installed, the output frequency is referred to an external refer enc e whic h will provide higher f r equenc y stability. It will also be possible to lock a group of modulators to one r eference. The possible exter nal reference frequencies are 6, 7, 8 and 10 M Hz .

The input impedance is always high, and a loop through connecti on is provided by the included BNC T-connector.

If t he level of the select ed external reference carri er bec omes too low the internal reference will automatically be sel ec ted.
