Chapter 7 — Bias Tee (Option 10)
7-1 Overview
Option 10 provides a bias tee that is installed inside the instrument. The bias arm is
connected to a 12 VDC-to-32 VDC power source that can be turned on as needed to place the
voltage on the center conductor of the instrument’s RF In port. This supply of bias implies it is
mostly useful when conducting two-port transmission measurements. This voltage can be
used to provide power to block down-converters in satellite receivers and can also be used to
power some tower-mounted amplifiers.
The bias can be turned on only when the instrument is in transmission measurement or
spectrum analyzer mode.
When bias is turned on, the bias voltage and current are displayed in the lower left corner of
the display. The 12 VDC-to-32 VDC power supply is designed to continuously deliver a
maximum of 6 Watts.
The bias tee menu can be accessed from the applications options menu and in transmission
measurement, it can also be accessed from the Measure main menu.
