Page 21: Introduction
SOQPSK/LDPC • STC/LDPC Of the aforementioned, RDMS™ provides true multi-symbol trellis demodulation in all three ARTM modes, PCM/FM, SOQPSK-TG, and Multi-h PCM. It also provides a clock signal, obviating the need for any outboard bit synchronizer. Modes that support LDPC use IRIG-standard low-density parity check coding to dramatically improve link margin by up to 9 dB.
Page 22: Nomenclature
Generation Rack-Mount RDMS™ 1.2 Nomenclature The Rack-Mount RDMS™ (hereafter referred to as “RM RDMS™”) is available in a plethora of variations based on the number of channels, frequency bands, demodulation methods, options, etc. The features and modes installed in each unit are identified in the model number, as depicted in Figure 1.
Page 23: Detailed Option Descriptions
Ethernet (EVTM) Payload, Receive Only – EN 1.2.2.3 When the EN option is enabled, the RDMS will recover EVTM encoded data and convert it from Serial Streaming Telemetry back to the original Ethernet packets. Standard SST operation is not replaced, and can still be used. This hardware must be paired with an -EN enabled transmitter for proper data recovery.
Page 24: Telemetry Over Ip - Ip
LDPC codes, and its error-correcting performance is inferior to LDPC. Therefore, LDPC is the preferred forward error correction if possible. The Viterbi Decoder control requires the K7 option, and the RDMS must be set to one of the following PSK modes: BPSK, QPSK, AQPSK, AUQPSK, OQPSK, or UQPSK.

In a single-channel configuration, waveform graphics are displayed on the left-most LCD and receiver settings are on the second LCD from the left. A static Quasonix logo is shown on the two right-most LCDs. In a dual-channel receiver, the two LCDs located to the right of the power switch are designated for Channel 1, while the other two LCDs are designated for Channel 2.

(BEP) allows DQE from multiple vendors to interoperate. The Quasonix DQM is based on statistics developed deep inside the demodulator. Bit Error Probability (BEP) is the calculated likelihood that a bit is in error. A very low BEP can be determined from only a few bits. BEP does not require any known data and can be determined quickly and accurately from demodulator statistics.

Page 57: Modulation Scaling (Pcm/Fm Mode Only)
4.4.2.12.1 Modulation Scaling – Tracking When the RDMS™ is powered on, the default setting is Acquire, unless the unit was powered off from a preset condition. If the unit was powered off from an unmodified preset setting, then the default condition of Modulation Scaling is as defined in the preset.
Page 58: Modulation Scaling - Hold
4.4.2.12.2 Modulation Scaling – Hold When the RDMS™ has a good lock on the target transmitter, Modulation Scaling should be set to Hold by highlighting the Mod Scaling option on the Main Menu and then pressing the Enter key on the keypad.
Page 59: Modulation Scaling - Off
4.4.2.12.4 Modulation Scaling – Acquire When the RDMS™ is powered on, the default setting is Acquire, unless the unit was powered off from a preset condition. Acquire mode has two states: Armed and Triggered. When Modulation Scaling is set to Acquire, in the absence of signal, the eye pattern will turn Yellow, as shown in Figure 51, the state is set to Armed.
Page 60: Modulation Persistence (Pcm/Fm Mode Only)
Generation Rack-Mount RDMS™ If the receiver is locked and the delta h (the change in modulation index) has settled below the delta h threshold for the specified settling time, the state changes to Triggered, and the eye pattern will turn Green. In Triggered mode, the estimated h (modulation index) is monitored but the scale is not updated.

The Phase Noise Comp option, shown in Figure 86, is used to set the Phase Noise Compensation (PNC) value to On, Off, or Auto. When set to Auto, the RDMS continuously checks and determines which mode (with PNC or without) has a higher data quality value and automatically sets the unit to that mode. Refer to section 9, Appendix C, for detailed information about Phase Noise Compensation.

Page 81: Mod Scale Index
Generation Rack-Mount RDMS™ Figure 90: Advanced Menu, DC Antenna Selection The downconverting antenna has an LO that is used to downconvert C band signals (4400 MHz – 5150 MHz) to a lower frequency range known as P band (400 MHz – 1150 MHz) using an LO frequency of 5550 MHz. This results in two issues that are addressed by the downconverting antenna control.

Page 83: Figure 94: System Block Diagram With Best Channel Selector
Generation Rack-Mount RDMS™ The Best-Channel Selector (BCS) is a revolutionary new feature, unique to the Quasonix RDMS™. Its purpose is to ensure that the back-panel data output from the Combiner is always optimal, even in rare cases where the Pre- Detection Diversity Combiner struggles relative to Channel 1 and Channel 2.

Generation Rack-Mount RDMS™ Figure 106: Advanced Menu, PCM Encoding Figure 107: PCM Encoding Selections 4.4.2.22 FEC Menu Forward Error Correction (FEC) may be accomplished by using Low-Density Parity Check (LDPC) encoding, in SOQPSK or STC modes, or by using convolutional encoding/Viterbi decoding, and/or ReedSolomon encoding in legacy PSK modes (BPSK, QPSK, OQPSK, AQPSK, AUQPSK, or UQPSK).
Page 92: Figure 110: Fec Menu, Ldpc Code
LDPC encoding is intended to improve performance specifically under harsh conditions, which might have a negative effect on AFC tracking. In general, Quasonix recommends setting the AFC Mode to Off if possible. This recommendation is especially important for the best LDPC performance. Refer to section 4.4.2.20 for additional information about AFC Mode.

Generation Rack-Mount RDMS™ Orient the receiving antenna in a direction that is expected to yield the lowest signal level that the receiver is likely to encounter. Activate AGC Zero under this condition by clicking on the Zero AGC button. The AGC output voltage is set to zero volts DC at a time when the receiver input is at its minimum value. This process ensures that the AGC output voltage will not cross through zero volts DC under normal operation.

Page 202: Appendix A - Recommended Am And Agc Settings For Acu Interfaces
Generation Rack-Mount RDMS™ 8 Appendix A – Recommended AM and AGC Settings for ACU Interfaces 8.1 AM and AGC In a typical flight test scenario, Automatic Gain Control (AGC) tracks out slow variations in received signal strength. Ideally, the net received signal has constant signal strength except for higher-frequency amplitude modulation (AM) induced by the antenna tracking mechanism.
Page 203 Generation Rack-Mount RDMS™ For example, suppose a conical scan system with no undesired low-frequency AM has a scan rate of 30 Hz. This system has a recommended AGC Time Constant of 1000 / 30 = 33.3 ms, and an AM Bandwidth of 5 * 30 = 150 Hz, with AGC Compensation OFF.

Page 205: Trellis Demodulation Summary
Generation Rack-Mount RDMS™ Figure 304: Phase Trajectory Never Forgets 9.1.1 Trellis Demodulation Summary The basic premise of trellis demodulation is that the signal from the transmitter follows a known path through the phase tree. When the demodulator knows this, it can use a sequence of several symbols to help make better decisions about each individual bit.
Page 206: Phase Noise Impact
This increase in bandwidth does have a tradeoff. A wider tracking range allows the RDMS to deal with the additional jitter, but it may also increase synchronization times slightly, and slightly increase the minimum SNR at which the RDMS declares lock.
