 Telemetry Transmitter

 Quasonix, Inc. 

 

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 supplies only valid data. Refer to Table 19 for user commands. 

1.2.15  Dual Power Option 

– DP 

The standard TIMTER™ operates at its full rated RF output power. The DP option provides two software-
programmed, hardware-actuated settings, designated by the user as “high power” and “low power”. There are 32 
choices for “high power” and 32 choices for “low power”.  The low power setting can provide as much as 24 dB of 
attenuation from the high power setting. 

1.2.16  Frequency Offset Option 

– 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. 

1.2.17  GPS Notch Option 

– GN 

Use this option to specify GPS notch filters to meet 115 dBm in 3 kHz band at L1 and L2 (hardware note). Available 
for S band only. Consult Quasonix for pricing and availability. 

1.2.18  High Bit Rate Option 

– HR 

The standard nanoTX™ 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 modes included with the PSK option. 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 SOQSPK-TG and MULTI-h CPM modes; 23 Mbps for PCM/FM and all legacy PSK modes.) Refer to the 
CF option for information about the Clock Free option. Refer to Table 12 for bit rate comparisons by mode.
