Rapid Measurement
Batch Measurements of Transmission Test Items
Example for PDC/PHS, only about 1 second is
required to measure all major transmission test items,
including frequency, modulation accuracy, origin off-
set, transmission rate, transmission power, leakage
power during carrier-off, rise/fall edge characteristics,
occupied bandwidth, and adjacent channel power.
Pass/fail decisions for limit value of each test item can
also be displayed.
Measurement of Antenna Power
Rise/Fall Edge Characteristics
Antenna power rise/fall edge characteristics can be
measured simultaneously with antenna power mea-
surements. In addition, the marker points can be
moved and the power can be read directly with 1/10
symbol resolution.
Calibration Functions
A built-in thermocouple power sensor is used for cali-
bration, providing accurate measurement of absolute
values such as average power with burst signal and
leakage power during carrier-off. There is no need for
other instruments; Just one press of the CAL key dur-
ing measurement performs calibration.
Modulation Analysis
The user can display the waveform as either frequency
deviation, eye diagram or constellation diagram to
easily show any irregularities in the modulation.
Constellation Display Functions
The I/Q vector components of measured signals are
displayed. The frequency error, RMS/PEAK vector
errors, and origin offset can be shown on the same
screen.
