POWER MEASURE
The R3131A can measure the power within
the specified band of frequency diffuse signals
and the total power of multicarrier signals It
can also be used to measure the occupied
frequency bandwidth (OBW) and adjacent
channel leakage power (ACP) which are
essential to transmission characteristics testing
for radio equipment
Channel Power
The R3131A allows you to measure the total power within the
window and display it as the channel power simply by setting
the measurement window to the specified occupied bandwidth
Total Power
Obtains the total power from the spectrum displayed on the
screen This function is useful for total power measurement of
multicarrier signals
OBW
Measures the frequency band which contains 99 of the total
power of the spectrum displayed on the screen In addition
the value of OBW can be set to any desired value
ACP
The measurement results can be displayed in graphical form
including upper and lower point data up to the 2nd ACP
respectively offset from the carrier and leakage power value at
all the displayed frequency points
POWER
MEASURESAVERECALL
The R3131A allows you to store and recall measured waveform
data and measurement conditions The R3131A unit offers up
to 10 dedicated files for storage In addition the builtin
standard floppy disk drive allows you to store them on MS
DOS formatted floppy disks
MULTIPLE MARKERS
Up to 10 markers can be set Therefore this feature is useful
for applications that require the measurement of each level of
multiple carrier signals filter cutoff characteristics etc at
multiple marked points
PASSFAIL
There is a choice of two types of limit tests for waves to be
measured One is a simple method in which either a signal
level or frequency is evaluated for wave shape in accordance
with a given window range The other is a limit line method
in which electromagnetic compatibility (EMC) and filter char
acteristics are evaluated in accordance with the limit lines
GATED SWEEP
Bursted signals could not directly be observed with former
spectrum analyzers The R3131A allows spectrum analysis of
the burst signal by supplying a trigger signal synchronizing
with the burst transmission
6 R3131A4E Jan ´02
GATED SWEEP OFF
GATED SWEEP ON
The window range set along the X and Y axes is the PASS area The
signal level or frequency at a marked point is evaluated in accordance
with the range
Any UPPER and LOWER limit lines can be set Pass or Fail judge
ment can be made in accordance with the limit linesEMC
This function measures electromagnetic interference generated
by various electronic equipment This function incorporates
the 9 kHz and 120 kHz RBW and QP detector conforming to
the CISPR Pub161 standard In addition using the AMFM
demodulation signal fed from the PHONE jack on the rear
panel you can identify broadcasting radio waves which act as
external noise Prior to measurement of noise emission on the
approved site this function is very useful for preparatory
evaluation and solution
Various antenna correction factors provided by Advantest are
builtin the R3131A Simply by selecting the Model name of
the antenna the level indication of the R3131A is calibrated to
an absolute value allowing you to read the value directly in
unit of dBµm When you use an antenna from other
manufacturers you can reflect its antenna correction factor in
the level indication of the R3131A by performing steps and
below
Diverse measurement functions
The MEAS key incorporates the XdB Down measurement
function which is useful for noise measurement AM
modulation measurement 2signal 3rdorder distortion
measurement and filter cutoff frequency measurement In
noise measurement bandwidth conversion can easily be made
and the PBW calibration function for improvement of
measurement accuracy is effective The PBW calibration
function is a new calibration function which performs
correction in power measurement based on conversion of the
R3131A resolution bandwidth filter to an ideal filter thereby
allowing measurement with higher accuracy

PERSONAL SPECTRUM ANALYZERImproved system throughput
The throughput of production and adjustment lines is largely
affected by the measurement time of measuring instruments
and data transmission time With newly developed internal
processing technology the R3131A has shortened the time
necessary for GPIB control and data transmission by half or
more in comparison with former products In addition by
reducing the settling time of the local oscillator the waveform
update rate in unit time has been doubled
(In either case comparison is made under the same conditions)

OPTION
The tracking generator (OPT74) is a monoblock option
which is integrated in R3131A It can generate constant level
signal synchronized with sweep frequency in the frequency
range up to 3 GHz and therefore can easily measure the
frequency characteristic of object device Besides with the
normalize function which cancels the frequency characteristic
of measuring system highly accurate measurement is possible
Because the output level can be set in a wide range (from 0 to
599 dBm in 01 dB steps) it can be used to measure filter
pass characteristic cable loss amplifier gain etc
For the measurement of reflection characteristic
With the SWR bridge the reflection characteristic of antennas
and filters can be measured
For the measurement of cable loss
With the short cable the highfrequency loss characteristic of
cable can be measured from the differential when the object
cable is connected
