Baseband Output 

Carrier tones of 95 kHz and 250 kHz are provided at 
this BNC connector.  One 50 

½ 

device may be con-

nected here using RG-58 cable.  Additional devices 
may be connected by “looping through” the connect-
ed device or by means of a suitable distribution 
amplifier.  The output impedance is 50 

½

Frequency accuracy is approximately ± .005%. 
Deviation is ± 50 kHz, maximum.  Average devia-
tion is dependent on program material and whether 
Limit mode or Compress mode is selected. 

Baseband Input 

An additional modulator may be connected here to 
allow combining carriers for channels in addition to 
95 kHz and 250 kHz. The input impedance is 50 

½

Power In 

21 VAC to 26 VAC only, 50 or 60 Hz.  (TFP 016 
Power Supply) Current consumption is approximate-
ly 300 mA. 

TX6 Transmitter 

Power Input 

Three-pin connector for TFP 010 power supply. 

Power Indicator LED (front panel) 

Located on the front panel in the top center of the 
LED window. Red indicator light glows when power 
is on. 

Note: The TX6 shuts off  when no baseband signal 
is present. 

Baseband Indicator LED (front panel) 

Located on the front panel in the bottom center of 
the LED window. Red indicator light glows when 
baseband signal is present. 

Baseband In: 

Connects to the Baseband Out jack of the MOD 112 
modulator or another TX6 transmitter. 

Baseband Out: 

Connects to the Baseband In jack of of the next TX6 
transmitter in the chain when multiple transmitters
