Product Description
PDI-3000E
MAGIC DVIP ADJACENT FREQUENCY TV MODULATOR
DESCRIPTION:
PDI-3000E MAGIC DVIP ADJACENT FREQUENCY TV MODULATOR depends on excellent VSB filters ,IF modulated signals processing.Its parasitic output inhibition degree is more than 60dB.Quadruple PLL technique is applied to audio and RF local oscillator, high frequency stability and nice output level and best accuracy.Micro computer CPU control.101 channels are available performed. Two bit LED screen displays the reality channel. More channels are available(PAL-D/K).Also it has resume Function.The RF output level reaches 115dBμV(M)above.Good video and audio linearity.There is a composite medium frequency input and output port in the back panel for the MMDS. It is also used in the head end of the digital TV system as well as the mobile signal test for the mobile manufactures.

Service manual
★ Safety and notes:
Do not use it when the atmosphere is hot and humid.Do not wash it with any liquid.
It is three core power cord. Please do not remove the third core.Make sure it connect with the cable TV smoothly through the earth.
It works when the switch is on.Please take the power switch off when you don't use.Please wait more than 5 seconds before you make it re-work.
Please make sure there is no electricity when you are connecting the audio and video input cables and RF output cables.
The raw data of the RF output level sets to 115dBμV(M),Make sure this value is good or not when it connects to the other equipment.Take care:Higher level value will disturb nonlinear distortion.
When it does not work, please check the audio and video as well as RF connecting cables, the set of the V/A, the RF level and the out-in Voltage.
If the equipment has been damaged,please return it to our agency or send it back to our company.
★ Installment and adjustment:
There are four fixed screw holes in the front panel to install it on a 19" TV set.
Please leave some space (≥45mm)between equipment to let the wind flow.
Please take of the power switch when you are connecting the cables of audio and video and RF.Also please keep an eye on the RF signal level value.
Please connect the Cable TV set to the RF output port with a 75Ω cable.Make sure the output level is the correct set.Please check the RF output level hole to set the level value at the front panel.
There is a test point in the front panel for testing when the equipment works.
Use this+-button to choose channels. PS a Manual book to show you the match relationship of digital display numbers with channels.
Re-set the A/V ratio. Its raw value is 18dB
