At the point when a period has been entered for the main month, all months can be chosen to duplicate this time setting for all months Using Up/Down catches will move choice through the six force levels Press Select to enter time choice

Slide 11

Control Section Local: Sets and confines control of J1000 capacities that can be controlled remotely, to switches on exciter front board Remote: When chose, all pushbuttons on exciter front board, aside from the RF Off switch, are debilitated and have no impact RF On: Turns on the J1000\'s RF power stage and chilling fans RF: Turns off J1000 RF power stage

Slide 12

Redundant Architecture A double exciter framework with programmed switchover is accessible to suit the most elevated repetition necessities. Exciters sustain two totally free and repetitive sign chains from AC to RF. Excess secluded outline has two complete and autonomous 500 watt broadband force modules, each with its own high productivity RF enhancer, modulator, switch mode power supply and vital ventilation fan.

Slide 13

Excellent Sound Quality Universal switch mode power supplies naturally conform working voltage to improve execution at any force level An incorporated exciter, utilizing propelled DDS innovation produces RF drive at the wanted working recurrence guaranteeing the most ideal sign propagation Feed an outside GPS reference clock sign to the J1000 controller for synchronous operation Plug-and-play HD Radio and DRM similarity

Slide 14

J1000 – Operational Features Switch mode power supply works from 170 V air conditioning to 270 V air conditioning Low voltage power supply works from 83 V air conditioning to 270 V air conditioning (auto-exchanging) Low voltage power supply keeps giving rationale circuits amid brownout RF intensifier is wideband with computerized RF drive - never needs tuning

Slide 15

Compact and Light Weight Compact outline takes into account speedy, savvy conveyance (next business day shipment from processing plant) and insignificant space necessities The control/exciter segment is 19 crawls wide and 7 creeps high (4U) and is side mounted for advantageous access to low level hardware The J1000\'s energy choice mounts in a standard 19" rack and is just 15 ¾ crawls high (9U)

Slide 16

Quick Frequency Tuning Simple change to any recurrence between 531 kHz and 1,610 kHz Requires field update pack, recurrence generator and counter, qualified professional and 1 hour Easy-to-use advanced controller. exciter, combined with dial up transporter recurrence determination RF channel just needs least part changes to tune to new recurrence band
