1 Introduction
1.1 Description
This document describes the Installation and Operation of Quasonix’ TIMTERTM Multi- mode Dual Telemetry
Transmitters. The 7.2 cubic inch TIMTER™ Dual Transmitter has a compact 2.0 inch by 3.0 inch design that
provides a single MDM-15 interface as a primary connector for power, clock and data, and serial communications,
while providing two separate RF outputs via SMA connectors. This single band configuration is ideal for two
antenna applications that utilize Space-Time Coding (STC) or Frequency Diversity. Quasonix also offers a 24 cubic
inch dual transmitter, which provides the same connectors while enabling multiple band functionality. The
transmitters are designed to transmit airborne telemetry data from a test article to ground stations. The transmitters
are developed, manufactured, and supported by:

1.2 Nomenclature
The earliest models of these transmitters were referred to as Tier I Missile Test Transmitters (TIMTER™) because
they were intended for missiles and offered only ARTM Tier I (SOQPSK) modulation. Although the model line now
includes much more than ARTM Tier I, and they are in widespread use on many platforms besides missiles, the
“TIMTER” name remains. Now in its third generation and commonly referred to as TIMTER™ 3, the transmitter is
available in a number of variations, depending on the options specified at the time of order. The type of features and
modes installed in each unit are identified in the model number, as depicted in Figure 1. Package field codes are
listed in Table 10. For questions about specific packages, please contact Quasonix.
Figure 1: Quasonix Part Number Construction Description
The words Terminal Control and Serial Control have the same meaning and are used synonymously throughout this
manual. Serial control originates from configuring the transmitter from a computer’s legacy RS-232/422 serial
communications (COM) port. Terminal Control reflects the more generic case where the transmitter could be
controlled by other standard computer interfaces such as Ethernet.

1.3.10 Automatic Carrier Wave Output Option —AC
This option allows the TIMTER to transmit a carrier wave when the clock input is absent, which would normally
cause the RF output to be turned off.
1.3.11 Adapter Plate –AP
Use this option to include the 2.5” x 3.5” adapter plate (hardware accessory) with the order.
1.3.12 Baud Rate Option –BRx
The BR option changes the serial communications default baud rate on the transmitter to the one selected. A number
from 0-8 follows the BR option request. Corresponding values are as follows: 0 = 57600 (Standard default for all
Quasonix transmitters); 1 = 4800; 2 = 9600; 3 = 19200; 4 = 38400; 5 = 56000; 6 = 57600; 7 = 115200, 8 = 230400.
1.3.13 CP07 Control Protocol Option –C7
The Quasonix interpretation of IRIG 106-17, Appendix 2-C serial control protocol (CP07) “provides standards for
commands, queries, and status information when communicating with telemetry transmitters configured with
communication ports.” The Basic command set contains the minimum (required) commands for transmitter control,
query, and status. The Extended command set contains optional commands that may or may not be implemented at
the manufacturer’s discretion. CP07 is enabled when the C7 option is requested.
The default baud rate for CP07 transmitters is 9600.

1.3.14 Convolutional Encoder Option –CE
The CE option enables convolutional encoding and NRZ-M conversion. This encoding adds redundant information
to the transmitted data stream to help detect and correct bit errors that may occur, particularly due to predominantly
Gaussian noise. Use of convolutional encoding requires a matching Viterbi decoder in the receiver to extract the
source data. The encoded data rate will be twice the source data rate, and the occupied bandwidth will also be
doubled.
For example, the transmitter has two encoders, one for in-phase (“I”) data and one for quadrature (“Q”) data. Call
the input symbol stream I0/Q0, I1/Q1, … . Each encoder outputs 2 bits for every input bit, so call the output bit
stream from the first convolutional encoder I0(1), I0(2), I1(1), I1(2), … , and call the output bit stream from the
second convolutional encoder Q0(1), Q0(2), Q1(1), Q1(2), … . Combining the outputs of the two encoders, then,
the output symbol stream is I0(1)/Q0(1), I0(2)/Q0(2), I1(1)/Q1(1), I1(2)/Q1(2), … .
For modes that do not employ Quadrature modulation, such as PCM/FM, Multi-h CPM, and BPSK, only a single
encoder is used.
A single encoder is implemented exactly as described in the “Consultative Committee for Space Data Systems,
Recommendation for Space Data System Standards, TM Synchronization and Channel Coding, CCSDS 131.0-B-1,
Blue Book, September 2003, Section 3.”
A basic convolutional encoder block diagram, as illustrated in CCSDS 131.0-B1, is shown in Figure 2.

1.3.15 Clock-free Baseband Interface Option –CF
Clock-free is an optional mode that transmits user data, but uses an internal bit sync to take the place of the normal
external clock. The standard TIMTER requires external clock and data inputs. With the CF option, no external clock
is required. The clock is generated directly from the data and a user-specified bit rate.
Because the internal bit sync’s clock takes the place of the normal external clock in clock-free mode, the selected
clock source must be external for clock-free just like it is for normal clock/data. This mode is most often used to
retrofit older analog transmitters in TM systems where the crypto device does not deliver a clock to the transmitter.
The commanded clock-free rate can be saved using the SV command, and if so, it will be restored at power-on.
When the CF option is used, the bit rate range is 0.1 to 35 Mbps for all waveform modes. It is limited by the bit rate
achievable for the current mode. (Refer also to the HR and LR options for extended bit rates, and the ID option for
Internal Clock and Data.)
Do not confuse the CF option with CS/DS commands.
Internal clock (CS 1 Command) is used when the transmitter is to be a test source only. The unit transmits the
selected internal data pattern (DS 1 command) at the bit rate set by the user via the IC command. The internal clock
is not used to transmit actual payload data.
External clock (CS 0 Command) is the normal mode: the user supplies clock and data, or in clock-free mode, the
user provides only valid data. Refer to Table 12 for user commands.
1.3.16 Clock Generator Output Option –CG
The standard TIMTER includes internal clock and data generators, generally used for system test. The CG option
enables this internal clock out of the unit on the primary MDM-15 connector. The assignment of output pins
depends on the other features selected.
1.3.17 Dual Power Option –DP
The DP option provides two software-programmed, hardware-actuated settings, designated as “high power” and
“low power”. There are 64 choices for “high power” and 64 choices for “low power.”Valid range is 0 to 31.5 dB in
0.5 dB steps.
1.3.18 Digital Switch Box Option –DSWBX
The TIMTER™ provides a standard configuration interface that is easily accessible via a computer terminal. Some
users prefer configuration via an external switch box. The 2nd Generation Quasonix switch box provides six LED
digits used to display the mode and frequency. This includes a total of five digits of frequency step up or down, in
MHz, and one digit of mode selection, in terms of the ARTM “Tier” number. There is also a channel selector for
channel 1 or channel 2. Two channel operation is only valid when connected to a Dual Telemetry Transmitter.
Standard transmitters default to Channel 1. An 18” MDM-9 to MDM-9 cable harness is included with the switch
box. (For use with the P9 option)
1.3.19 Frequency Offset –FO
This option is used to set frequencies that are NOT aligned to the synthesizer step size for their units, typically 500
kHz, and it enables the FO user command.
1.3.20 High Bit Rate Option –HR
The standard TIMTER supports bit rates from 0.1 to 28 Mbps in SOQPSK-TG and MULTI-h CPM modes, 0.05 to
14 Mbps in PCM/FM (Tier 0) mode and in all legacy modes. The HR option increases the bit rate to a maximum of
46 Mbps (23 Mbps for PCM/FM). (The maximum bit rate with a Clock Free transmitter is 35 Mbps for SOQPSK-
TG and MULTI-h CPM modes; 23 Mbps for PCM/FM and all legacy modes.) Refer to the CF option for
information about the Clock Free option. Refer to Table 11 for bit rate comparisons by mode.

1.3.21 Internal Clock and Data Option –ID
The ID option allows the CS and DS user settings to be reloaded on power up or on a manual recall of a setup.
Without the ID option, CS and DS are both forced to 0. Refer to the CF option for information about the Clock Free
option.
1.3.22 Limited Current Option —LC
This option is used to specify low current in the RF Off state. Current draw is less than 10 mA when the transmitter
is Off. This is a hardware option.
1.3.23 Forward Error Correction / Low Density Parity Check (LDPC) Option –LD
This option provides the Low Density Parity Check (LDPC) encoding, which is being considered for use on the
iNET program. LDPC has been adopted by the Range Commander’s Council, IRIG 106-17, Appendix 2-D.
1.3.24 Forward Error Correction / Low Density Parity Check (LDPC) Option –LD6
This option adds the extended LDPC option to the unit. It lets the user select from the six implemented LDPC codes,
and allows the randomizer command to select the CCSDS randomizer, if LDPC is enabled. Adding this option
automatically enables the existing LD option.
The IRIG standard calls out six variants of LDPC codes—all combinations of two different information block sizes
(k=4096 bits and k=1024 bits) and three different code rates (r=1/2, r=2/3, and r=4/5).

1.3.25 Low Bit Rate Option –LR
The standard TIMTER™ supports bit rates from 0.1 to 28 Mbps in SOQPSK-TG and MULTI-h CPM modes, 0.05
to 14 Mbps in PCM/FM (Tier 0) mode and in all legacy modes. The LR option decreases the bit rate to a minimum
of 50 kbps (25 kbps for PCM/FM). (The minimum bit rate with a Clock Free transmitter is 50 kbps for all modes.)
Refer to the CF option for information about the Clock Free option. Refer to Table 11 for bit rate comparisons by
mode.
1.3.26 Modulation Scaling Option –MS
This option enables the MS and MJ commands which allow a user to set the modulation scaling factor and scale the
modulation index of the transmitted signal. For additional information, refer to Table 12, or contact Quasonix.
1.3.27 Hardware Preset Option –PS (PS2, PS4, PS8, or PS16)
The TIMTER™ supports one or more hardware presets. A single preset defines the complete state of the transmitter,
including carrier frequency, modulation mode, data polarity, randomizer state, etc. Without the PS option, the
TIMTER™ supports only one hardware preset, which it reverts to at power-up. The PS in the option string specifies
that the unit supports multiple hardware presets (2, 4, 8, or 16). Presets are engaged by grounding various
combinations of pins on the terminal/parallel control selection. The number of presets available and which pins
engage the presets depend on the other features specified. Due to the limited number of pins available, the PS option
may require the elimination of the RF On/Off pin. Due to firmware part number parsing requirements, the hardware
preset option code must be at the very end of the part number to be valid. On units which use the standard MDM-15
connector, the ZY command displays the connector pinout showing preset pin locations. For additional information,
refer to Appendix A –Preset Option.
1.3.28 Recall Holdoff Option –RH
If this option is enabled, AND the recall holdoff pin is held low on powerup, THEN the software will do an ‘RF 0’
to prevent the RF output from coming on until the user explicitly enters ‘RF 1.’ If the pin is high, then this option
has no effect.
1.3.29 Space-Time Coding —STC
Space-Time Coding is a waveform coding technique that uses transmit diversity to avoid destructive interference in
two-antenna systems with a similar bandwidth and power efficiency of SOQPSK. It has been adopted by the Range
Commander’s Council, IRIG 106-17, Appendix 2-E.
1.3.30 Variable FIFO Depth Option –VF
This option enables the VF command which allows the user to set the FIFO depth on the transmitter for controlling
latency time between bits in and bits out. The range is 0 to 255 with 128 being the default. If no value is entered, the
current value displays.
1.3.31 Variable Power Option –VP
The standard TIMTER™ operates at its full rated RF output power. The software-based VP option provides 64
discrete power level settings. Valid range is 0 to 31.5 dB in 0.5 dB steps.
