Frequency Converter Interface (Option 6)
Introduction
Option 6 provides added circuitry and a connector to provide power, control signals and a
local oscillator signal to a frequency converter.
The Anritsu FCN4760 4.7 GHz to 6.0 GHz Frequency Converter can be used with this op-
tion. When the frequency converter is attached to the Site Master, the frequency range of
the combination becomes 4.7 GHz to 6.0 GHz.
NOTE: The frequency converter interface (Option 6) and the FCN4760 fre-
quency converter apply to Spectrum Analyzer mode only.
Bias Tee (Option 10)
Introduction
Option 10 provides a bias tee installed inside the S332D Site Master. The bias arm is con-
nected to a fixed 18 Vdc power source that can be turned on as needed to place the
18 Vdc on the center conductor of the
RF In
port. This voltage can be used to provide
power to block down-converters in satellite receivers, and to power some tower mounted
amplifiers. Bias can be turned on when the instrument is in either spectrum analyzer or
transmission measurement mode. When bias is turned on, the bias voltage and current are
displayed in the upper left corner of the display. The 18 Vdc power supply is designed to
deliver 300 mA continuously and up to 1A peak for 200 ms.
NOTE: The Bias Tee option cannot be used in conjunction with the Anritsu
FCN4760 Frequency Converter Module (Option 6).
