PIDA-1000
Braodband Bi-directional Push-Pull Distribution Amplifiers
The Pico Macom PIDA series two-way broadband distribution amplifiers are high quality dual push-pull amplifiers producing forward and reverse signals with extremely low
distortion and high output levels. These amplifiers are designed for bi-directional cable
distribution systems used in institutional and MDU environments, which employ reverse
path signals such as cable modems, remote status monitoring, and remote TV origination. The PIDA also makes an excellent headend launch amplifier and is frequently
used in conjunction with Pico Macom’s passive headend combiners (PHC12G or
PHC24G) to overcome losses associated with signal combining in broadband CATV
systems. Furthermore, the PIDA can be used in cable systems whose input source is a
franchise cable drop or the output of a SMATV headend. In such applications, the PIDA
would be used with Pico Macom’s CEF channel elimination filter for “mix-and-match”
channel selection or for local insertion. The PIDA enclosure is made of high-grade
aluminum to ensure reliable heat dissipation and corrosion resistance. Pico Macom
backs up this product with its industry leading 5-year limited warranty.

Installation Procedure
PIDA-1000
Installation
1. Mount unit securely by attaching screws or bolts through mounting tabs of unit and into an equipment rack, wall or other solid structure.
2. Attach the source RF signal to the input of the PIDA-550/1000.
3. Attach the distribution RF cable to the output of the PIDA-550/1000.
4. Connect unit power cord to wall receptacle or power strip supplying line power.
5. Connect a RF spectrum analyzer or signal level meter to the input test point.
6. Use the loading chart listed on a previous page as a guide to ensure that the input level does not exceed the suggested amplitude level for the number of channels. If needed, reduce the input level using plug in attenuators (PIDA-AT-*) and equalizers (PIDA-EQ-*) for proper operation.
7. Connect a RF spectrum analyzer or signal level meter to the output test point.
8. Adjust the amplifier output level to match the distribution amplitude and tilt requirements.
9. If 5-36MHz return RF signals are present, measure the input level at the output “-30dB” TEST” point location. Using plug in attenuators (PIDA-AT-*) to
ensure that the return input level is between 1to 25dBmV. Adjust the “RETURN PATH GAIN” control to match distribution system design requirements.
Note:
The channel loading chart on a previous page shows the proper operation level for the PIDA-550 and PIDA-1000. The setup procedure above and loading restrictions assume that the RF source channels are all received at the same amplitude level. Please note the listed performance criteria is for SPECIFIC numbers of channels, and must be de-rated accordingly when inserting additional channels. Also note the amplifier's gain does not change.
However, as the number of channels increases from 7 channels, the input level (hence, the output level) must be reduced. Exceeding the input levels listed below will cause intermodulation and picture distortions.
If return level is higher than +25dBmV, the return amplifier stage may be bypassed using internal jumpers (see diagram showing jumper locations).

Uptime Loaner Program
Our Uptime loaner program is designed to provide domestic users of our headend products and commercial systems the best possible support and service. This
program is established to minimize downtime resulting from equipment failure in critical service situations. We offer this program free-of-charge (excluding freight)
to qualified purchasers within the warranty period. The program provides a free equipment loan of like qualified equipment enabling seamless operation for the time
required to repair and return the unit.
The process is simple. Call our Customer Service desk requesting a return-merchandise-authorization (RMA) number for the failed equipment and ask for a loaner
unit. We will issue an invoice for the List Price of the loaner unit plus shipping costs. When you receive the loaner unit, pack the failed unit in the loaner unit’s box
and ship it freight prepaid to Pico Macom for repair. When you receive the repaired unit, a new RMA number will be provided in the box. Carefully pack the loaner
unit and affix the new RMA number on the box and ship it back to us for full credit excluding shipping costs.
To qualify for the program, you must have current open-terms with us and in good standing. We must receive your failed unit within one week after the loaner unit
is shipped to you, and must likewise receive the loaner unit within one week after the repaired unit is shipped back to you. Daily rental fees not to exceed 10% of
the equipment’s List Price will apply beyond one week after the loaner or repaired unit are shipped to you. Other limitations may apply, so please call us for additional information on qualifying equipment and procedures. Pico Macom reserves the right to modify or discontinue the Uptime Loaner Program at any time, and at
its sole discretion.

Frequently Answers and Questions

What is the purpose of the "fwd slope" and "fwd gain" controls?
The "fwd slope" control adjusts the slope of the forward path amplifier, while the "fwd gain" control adjusts the overall gain level. These controls allow for optimal carrier-to-noise ratio and picture quality.
What is the difference between passive and active reverse-path gain modes?
In passive mode, the reverse path signal is not amplified, while in active mode, the signal is amplified and can be adjusted with a gain control. The choice of mode depends on system requirements and signal levels.
What is the purpose of the -30dB input and output test points?
These test points allow for simplified setup and performance monitoring without service interruption.
