USER MANUAL MPD-1611291-A EXACT-V2 High End Rack Modulator / Exciter 2.2 Input Stream Interfaces 2.2.1 ASI/SMPTE Inputs The unit offers 2 ASI/SMPTE inputs compliant either with DVB-ASI ([D1] & [D2]) or with SMPTE 310M. They can be used either in single or redundant mode. 188 or 204 byte packets without RS coding and 204 byte packets with RS coding are supported when used in ASI mode. If 204 byte packets including RS coding are provided, then the RS error checking and correction are performed.
USER MANUAL MPD-1611291-A EXACT-V2 High End Rack Modulator / Exciter 2.3.1 TS CleverSwitch Control CleverSwitch is a flexible input redundancy management mechanism designed by Hitachi-Comark. It is enabled by default and can be manually disabled or enabled. Figure 2: TS CleverSwitch block diagram CleverSwitch is based on a programmable consecutive error threshold. Once it is reached, the stream selection switches automatically from the primary input to the secondary.
USER MANUAL MPD-1611291-A EXACT-V2 High End Rack Modulator / Exciter 2.3.2 Seamless Switching The switching (and switching back) performed by the TS CleverSwitch between the primary and the secondary stream is not expected to be seamless. However, if the exact same data stream is present on both inputs (Primary & Secondary) then the modulator performs seamless switching between inputs. Switching is made on a packet basis. 2.
USER MANUAL MPD-1611291-A EXACT-V2 High End Rack Modulator / Exciter 2.6 Digital Precorrection The digital pre-correction feature is available for both ATSC 1.0 and ATSC 3.0 signal waveforms.
USER MANUAL MPD-1611291-A EXACT-V2 High End Rack Modulator / Exciter The use of adaptive precorrection is generally preferred not only in order to reach higher performance and efficiency, but also in order to save on technician time. However, when several RF signals are combined together (adjacent channels), the use of Linear DAP is not possible because the feedback signal is then a combined spectrum of several channels. In that case a manual Linear precorrection is needed.
USER MANUAL MPD-1611291-A EXACT-V2 High End Rack Modulator / Exciter 2.6.1 Digital Adaptive Precorrection The Digital Adaptive Precorrection (DAP) block is illustrated here below. Figure 6: DAP integration block diagram The DAP function is composed of Non-Linear and Linear Precorrection and a dedicated down-converter. The down-converter receives the signal feedback after the external amplifier (FBA_In) and after the RF filter (FBF_In).
USER MANUAL MPD-1611291-A EXACT-V2 High End Rack Modulator / Exciter • SINGLE DAP: The DAP process is manually started and is stopped either by a timer value (user configurable) or manually stopped. Figure 7: Single DAP mode operation • SURVEY DAP: In this mode, the DAP process is started as the Single DAP mode. Once the timer is reached, then the DAP process can be automatically restarted if a shoulder or MER deviation is detected (user configurable).
USER MANUAL MPD-1611291-A EXACT-V2 High End Rack Modulator / Exciter • CONTINUOUS DAP: The DAP works continuously until the user exits continuous mode. Figure 9: Continuous DAP mode operation 2.6.1.2 Linear Adaptive Precorrection The purpose of Linear precorrection is to correct the distortion in amplitude and in group delay of the output filter. The precorrector is based on a complex FIR filter which can correct up to 3dB (range -3dB to 3dB) in amplitude and up to 3µs (range 0 to 3µs) in group delay.
USER MANUAL MPD-1611291-A EXACT-V2 High End Rack Modulator / Exciter 2.6.2 Manual Digital Pre-correction In addition to digital adaptive precorrection, EXACT-V2 also performs manual linear precorrection. Using the “MANUAL EDIT” mode, both amplitude and phase corrections are performed over the full spectrum of the signal. For this purpose, a table of 32 points can be loaded in the modulator with the Set Linear Curves command.
USER MANUAL MPD-1611291-A EXACT-V2 High End Rack Modulator / Exciter Figure 10: Sharp Filter Profile menu 2.7 Output Processing The nominal output level of the main output “RF Out” is 0 dBm for the standard exciter and 20dBm for the exciter with optional preamp. An attenuation between 0 and 17 dB per increment of 0.1 dB can be set. In addition, an offset gain between -1 dB and + 1 dB per increment of 0.1 dB can be set. If needed, the output spectrum can be reversed.
USER MANUAL MPD-1611291-A EXACT-V2 High End Rack Modulator / Exciter The “RF Maintain” feature consists in keeping an RF signal presence out of the modulator in order to allow a constant power at the modulator RF output during an input stream error (the function “RF Maintain on Input Stream Error” shall then be enabled). The overall objective is to avoid any RF signal interruption at the output of the modulator for protecting the amplifier.
USER MANUAL MPD-1611291-A EXACT-V2 High End Rack Modulator / Exciter from 8dB to 20dB. The default value is 10 dB, meaning that a light crest factor reduction is performed. The following figures display the Crest Factor parameter impact on a signal: Crest Factor setting = 20dB (No reduction) Without any crest factor reduction, the PAPR is 14.4dB Crest Factor setting = 11dB After the adjustment, PAPR is 10.
USER MANUAL MPD-1611291-A EXACT-V2 High End Rack Modulator / Exciter 2.7.2.2 Crest Factor Optimization Parameter In order to allow the best amplifier efficiency a “Crest Factor Optimization” parameter has also been added. It is active when the crest factor reduction is enabled (value ≠ 0). For a given “Crest Factor”, the “Crest Factor Optimization” enhances the signal shoulders.
USER MANUAL MPD-1611291-A EXACT-V2 High End Rack Modulator / Exciter 2.7.2.3 Protection Clipping Parameter Since adaptive precorrection can produce power peaks at the modulator output, a “protection clipping” has been added at the output of the modulator. It will allow the user to protect the amplifier input by clipping the signal out from the modulator. Note: Protection Clipping = 20 means OFF Recommended value to start = 15dB (default value) 2.7.
USER MANUAL MPD-1611291-A EXACT-V2 High End Rack Modulator / Exciter DAP mode activation In the Settings Tab, the DAP mode can be enabled under Outputs > Precorrections: Note: Enabling or disabling the DAP causes a reset of the non-linear curves. The user is then given the possibility to save the current curves, if needed. Non-Linear DAP launch The same protocol as the basic DAP applies (please refer to the previous chapter).
USER MANUAL MPD-1611291-A EXACT-V2 High End Rack Modulator / Exciter 2.8 Clock and Synchronization The clock and synchronization function is responsible for synthesizing the required temporal signals and data rates. A high-stability 10 MHz OCXO provides the internal clock reference. However, if synchronization with other equipment is required, an external 10 MHz clock signal can be chosen as a reference together with external 1PPS.
USER MANUAL MPD-1611291-A EXACT-V2 High End Rack Modulator / Exciter The figure below shows the entire VX20-x0x2 synchronization processing block (the on-board GPS being depicted as “GPS receiver”): Figure 13: VX20-x0x2 synchronization processing block Then, depending on the user’s setup, three cases can be considered: 1) Working with external GPS signal reference (using on-board GPS receiver): Figure 14: VX20-x0x2 clock synchronization - GPS signal In this case, the modulator processes the 1PPS due to
USER MANUAL MPD-1611291-A EXACT-V2 High End Rack Modulator / Exciter 2) Working with external 1PPS reference signal: Figure 15: VX20-x0x2 clock synchronization – external 1PPS signal In this case, the modulator directly uses the 1PPS available from the external source available on the 1PPS I/O interface. This 1PPS reference signal is used for both temporal synchronization and 10 MHz PLL locking.
USER MANUAL MPD-1611291-A EXACT-V2 High End Rack Modulator / Exciter 2.8.2 Warm-up Time This part aims at describing the WARM-UP function which has been designed for compensating the start-up delay of the OCXO (for instance, in case of AC power loss). In order to be stable the internal temperature of the OCXO must be stabilized and equal to 85°C. However, this could take up to 5 minutes to obtain a stable 10MHz reference.
USER MANUAL MPD-1611291-A EXACT-V2 High End Rack Modulator / Exciter The PLL_Unlocked status (Mute on SFN Not Ready) is used in order to maintain that the output signal is muted (please refer to the mute conditions in chapter RF output muting and RF maintain features.) In case of SFN application, an optional functionality “PPS auto resync” is available to allow resynchronization of the internal PPS (used as a reference time in SFN) when 10MHz clock control is locked.
