Information
INTRODUCTION
The Racal-Dana RF Level Meter Model 9303 is a versatile,
microprocessor controlled instrument. It will make
measurements on signals having crest factors up to 15 and
r.m.s. voltage levels between 30 pV and 3.162 V. The
instrument has an auto ranging facility, but provision for
manual setting of the range is provided.
The full quoted accuracy is obtained over a frequency range
from 10 kHz to 2 GHz. The instrument features an auto
calibration facility. The calibration factors relating to
the measuring heads are stored during the calibration
procedure, and are used to adjust the displayed measurement
without further operator action. A calibration signal source
is provided for use should re-calibration of the measuring
heads become necessary.
The instrument measures the true r.m.s. voltage of the
applied signal. This may be displayed in voltage units, or
converted to:
(a) Indication of power, computed as V^/R, where R is a
resistance value stored in the instrument.
(b) Indication of power relative to a power level which has
been stored in the instrument. This may be displayed as a
numeric ratio or in dB.
(c) Indication of the percentage difference between the
measured voltage or the computed power and a voltage or
power level which has been stored in the instrument.
(d) Indication of the difference between the measured
voltage or the computed power and a voltage or power level
which has been stored in the instrument.
(e) Indication of the ratio of the measured voltage to a
voltage level which has been stored in the instrument. This
may be displayed as a numeric ratio or in dB.
The instrument features a large, four digit, liquid crystal
display (LCD). Coarse and fine light dot displays form part
of the display, and provide a pseudo-analogue form of
indication. Units annunciators, operation limit warning
indicators and calibration factor indicators are also
incorporated.
