The transmitter output level is variable from +20 to +50

(1)

dBmV in 2

dB increments. The output level will be attenuated by the tap value

of the directional coupler. For example, if a sweep signal level of

+16 dBmV is desired on the system and the output of the 3ST

Transmitter is set to +36 dBmV, a directional coupler value of 20 dB

may be used, or the combination of a lower value directional coupler

and an attenuator pad.

An alternate method would be to insert the 3ST Transmitter output

at one of the combining network inputs, and connect the (transmit-

ter) reference input to the headend amplifier input test point. This

method eliminates the need to add directional couplers at the

combiner output.

dure", page 4-1.
