Instruction Manual
THERE ARE NO USER SER VICE ABLE PARTS IN THIS UNIT.
INFORMATION BELOW IS FOR QUALIFIED INSTALLATION PERSONNEL ONLY
Field Installable Optional Modules.
Take care not to bend jack pins when plugging in modules - view orientation of pins through holes provided - pins are polarized to prevent
wrong installation - see Location Diagram.
Leakage-current and/or resistance measurements should be made by service technician after repairs are completed to determine that
exposed parts are acceptably insulated from the supply circuit.
BIDA-CE Cable Equalizer
Stock No. 5475 (for BIDA 550 MHz) = BIDA CE-5-(*)
Stock No. 5477 (for BIDA 750 MHz) = BIDA CE-7-(*)
Stock No. 5478 (for BIDA 860 MHz) = BIDA CE-8-(*)
Stock No. 5479 (for BIDA 1000 MHz) = BIDA CE-9-(*)
Plug-in cable equalizer for increasing forward slope in BIDA series
amplifiers. The BIDA-CE pro vides attenuation that varies inversely with
frequency to correct in her ent tilt of coaxial cable used in dis tri bu tion
systems. A sheet metal cover is mounted over the circuitry to improve
stability while preventing ac ci den tal detuning during ship ping, han-
dling, and in stal la tion. The BIDA-CE is available in fixed values of 3, 6,
9, 12, 15 and 18 dB. Before inserting, remove the factory installed "0
dB" jumper wire W2 (between J6 & J8). Loosen mounting screw and
rotate Cable Equalizer clamp clock wise. After in sert ing Cable Equalizer,
rotate Cable Equalizer clamp counter-clockwise so it lays atop the
mount ing tab. Tighten mounting screw to secure Ca ble Equalizer
clamp po si tion, (View A).
* Specify dB value.
BIDA-FA-(*) Flat Attenuator
Stock No. 5411A
Plug-in flat attenuator pad for reducing forward and/or return gain in
BIDA series amplifiers. The BIDA-FA is avail able in fixed values of 1-20 dB
in 1 dB steps. Be fore in sert ing, remove the fac to ry installed "0 dB"
jumper wire W1 (between J3 & J5) for for ward and W3 (between J14 &
J16) for return.
* Specify dB value.
Note: The unit is shipped with 18 gauge jumpers which are not re-installable. Do
not remove jump ers except when installing optional equipment modules.
Accessory Identification
For future reference, it is recommended that the type and value of the
accessories installed in the BIDA be marked in the space provided on
the front panel. The full sized reproduction may also be copied and
used for that purpose.
