Operational Description: The EC704MP[BB3 digital transmitter system is an up to 450W average power (when using ATSC 1.0 8VSB modulation), 420W average power (when using ATSC 3.0 COFDM modulation) that consists of a Hitachi Kokusai Electric Comark (HKCM) Exact V2 digital exciter, Hitachi Kokusai Electric Linear (HKL) CM-8001 Drive controller, one (1) HKL PA704MP Amplifier, a passive hybrid combining system, an HKL 40243 Low pass filter, and a Com-Tech FC6D80C 6 Pole Mask Filter (or equivalent). The final stage of amplification operates at 50VDC and 20A at full power. This system is used to provide an ATSC 1.0 (8VSB) or ATSC 3.0 (COFDM) modulated signal over the UHF channels 14 through 36 in a manner consistent with FCC Part 74. Output power from, maximum power to 0W depending on the modulation standard, is controlled via attenuator circuitry in the CM-9001 Drive controller.

REV B — 22 Nov, 2021 1 Technical Service Bulletin 190425 RF Tuning Procedure for Transmitters Using Exact V2 Exciter The Comark Exact exciter has a very capable / powerful non-linear digital pre-corrector con- tained in it. Knowing how to set up and properly adjust this corrector is key to the best perfor- mance and safe operation of a transmitter. Described below is a basic guide to allow a user to accomplish the proper tuning adjustment of this corrector. 1. Overview Panel First insure that the transmitter is properly connected to the output mask filter and load. Ensure that you have RF output couplers in the path before and after the mask filter for transmitter feed- back to the Exact exciter. Log into the Exact Exciter’s webpage and configure the correct output modulation type, bandwidth, and frequency in the RF Output Parameters tab. 2. Basic Setup On the rear panel there are 2 SMA connectors labeled FBA (Feed Back Amplifier), and FBF (Feed Back Filter). The FBA signal should come from the transmitter output sample before the mask filter. This is used for non-linear (shoulder) correction. The FBF signal should come from the transmitter output sample after the mask filter. This is used for linear (SNR) correction. These signal levels should be in the range of -15 to -5 dBm. 3. Connecting Feedback Signals Fig. 1 Rear panel REV B — 22 Nov, 2021 2 Technical Service Bulletin 190425 4. Checking the Feedback Signals Levels Once the feedback signals are connected, the user can check, in the Exact Precorrections tab, that they are properly wired, synchronized, and that their power levels are in accordance with the specifications. Fig. 2 Exact Output Precorrections tab 5. Connecting Feedback Signals The only parameters that need to be set before launching the DAP are Crest Factor, Protection Clipping, and Timer (Correction Time). 6. Crest Factor Setting Since the Exact is performing a clever PAPR reduction, less destructive for the signal compared to the amplifier, the Crest Factor has to be reduced as much as possible by Exact instead of the amplifier. As a tool, the Crest Factor value monitored from the amplifier feedback signal can be used as a guide / starting point. Once the transmitter is at full power and before correction is run for the first time, the crest factor / PAPR can be read in the FBA Measurements section of the Precorrections tab in the Outputs section of the GUI. This is the Crest Factor / PAPR that the Exact is measuring on the transmitter output without correction. The recommended starting point is to set the Crest Factor setting only about 1dB higher than the value which is monitored in the FBA Measurements sec-tion. This should not be set to what you believe the Crest Factor / PAPR should be when you are finished correcting or as referenced by any other measurement means. 7. Protection Clipping Setting Protection Clipping is just what the name implies. It is the maximum level of PAPR allowed out of the exciter when correction is run. Because the DAP corrector simply tries to make the feed- back signal as close to perfect as possible it essentially knows no limits of how far it can stretch peaks unless told otherwise. If this is not kept to a “reasonable” level it could result in amplifier damage. A good guideline is to keep this only about 3dB above the crest factor setting. Once REV B — 22 Nov, 2021 3 Technical Service Bulletin 190425 7. Protection Clipping Setting cont. correction has run, it should be adjusted down by 1dB from where it is set to see if there is a performance impact. If not, then leave it alone. It should only be carefully increased in small increments to see if increasing has any positive effect on signal performance. Essentially, it should be adjusted only as high as necessary to achieve acceptable performance. Fig. 3 Non Linear Precorrections screen followed by the RF Output Parameters screen Once the Crest Factor and Protection Clipping have been set, the DAP can be launched in the Precorrection Menu, using one of the following modes: “Single” mode (recommended), where the DAP will be automatically stopped after a user config- urable “Timer” value. “Continuous” mode, where the DAP works continuously until the user exit the continuous mode 8. Timer Setting In the Precorrections tab if “Single” mode is selected the amount of time the corrector will run can be adjusted. In most cases 3 to 5 Minutes is sufficient for good performance of the non-lin- ear corrector. By not setting the value too low or short, the shoulder performance may not reach its best performance level as the corrector has not run enough iterations of correction to linear-ize the transmitter optimally. By setting it excessively high or long, the transmitter performance will have already reached the optimum performance before the corrector has stopped. Setting it too long can potentially have ill effects in that the shoulders could become “over corrected” and not be at optimum performance. 9. Crest Factor Parameter Setting Fine Tuning After a first run of DAP (in “single” mode with a timer value set), it is usually possible to fine tune the Crest Factor setting in order to improve the achieved shoulders performance. This change should be made in small increments (0.1 to 0.3dB) either up or down from the original set value while observing the shoulder performance. If the performance gets better, try going a little more in that direction until the performance starts to degrade then back up a bit to the best performance. Once this is done, reset the correction, and re-run the DAP. This should yield equal or perhaps slightly better performance. The corrector is now optimally adjusted. REV B — 22 Nov, 2021 4 Technical Service Bulletin 190425 10. Crest Factor Optimization Parameter Setting For a given “Crest Factor”, the “Crest Factor Optimization” enhances the signal shoulders. Find- ing the best value for this parameter allows the user to gain performance on the shoulders of the signal,…
