1.3.33 Low Bit Rate Option
– LR
The standard TIMTER™ supports bit rates from 0.1 to 28 Mbps in SOQPSK-TG and ARTM 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). Refer to the CF option for information about the Clock Free option.
Refer to Table 12 for bit rate comparisons by mode.
1.3.34 Space Operations and Research S band Option
– MA
This option enables frequencies below Lower S band (generally used for Space operations and Space research
applications). The frequency range is 2025.0 MHz to 2110.0 MHz with a default frequency of 2050.5 MHz in 0.5
MHz tuning steps. Maximum power currently allowed is 10 W.
1.3.35 Space Operations and Research S band High Limit Option
– MAH
This option extends the upper MA band frequency to the frequency which follows this option, in MHz, such as
MAHxxxx. Limit must be within roughly 100 MHz of band range.
1.3.36 Space Operations and Research S band Low Limit Option
– MAL
This option extends the lower MA band frequency to the frequency which follows this option, in MHz, such as
MALxxxx. Limit must be within roughly 100 MHz of band range.
1.3.37 The standard Randomizer Control Option
– MK
The standard TIMTER™ provides a user command (RA) that reports or sets the randomizer state. This option
enables ON/OFF control of the randomizer with a hardware pin. Use this option to specify the Randomizer Control
(hardware configuration) with the order.
1.3.38 Modulation Scaling Option
– MS
This option enables the MS command which allows a user to scale the modulation index of the transmitted signal.
For additional information, refer to Table 13, or contact Quasonix.
1.3.39 MDM-9 Accessory Board
– P9
Use this option to include the MDM-9 Accessory Board (sometimes referred to as a “tophat board”) (hardware
accessory), for use with switch box part number QSX-AC-SWBX-P9-3B-3M, with the order.
1.3.40 Parallel Port Frequency Programming Option
– PF
This option adds a parallel port in the form of an MDM-15 connector for manual frequency tuning. The PF option
requires the addition of a Quasonix MDM-9 Accessory Board. Consult Quasonix to order the PF option.
