TEST PORT CHARACTERISTICS
The specifications in the following table apply when the
proper Model 34U Universal Test Port Adapters are con
-
nected, with or without phase equal insertables, to the test
set ports and calibrated with the appropriate Anritsu or
other designated calibration kit at 23°C ±3°C using the
OSL calibration method with a sliding load to achieve
12-Term error correction (A 90 minute warm-up time is rec
-
ommended.)
MEASUREMENT CAPABILITIES
Number of Channels: Four independent measurement
channels.
Parameters: S11, S21, S22, S12, or user-defined com
-
binations of a1, a2, b1, and b2. All measurements are
made without the need to manually reverse the test device.
Measurement Frequency Range: Frequency range of
measurement can be narrowed within the calibration range
without recalibration. CW mode permits single frequency
measurements, also without recalibration. In addition, the
system accepts N discrete frequency points where
2£N£1601.
Domains: Frequency Domain, CW Draw, and optional
High Speed Time (Distance) Domain.
Formats: Log Magnitude, Phase, Log Magnitude and
Phase, Smith Chart (impedance), Smith Chart (Admit
-
tance), Linear Polar, Log Polar, Group Delay, Linear Magni
-
tude, Linear Magnitude and Phase, Real, Imaginary, Real
and Imaginary, SWR, Power.
Data Points: 1601 maximum. Data points can be
switched to a value of 801, 401, 201, 101, or 51 points
without recalibration (if 1601 points were used in the cali
-
bration). In addition, the system accepts an arbitrary set of
N discrete data points where: 2£N£1601. CW mode per
-
mits selection of a single data point without recalibration.
Reference Delay: Can be entered in time or in distance
(when the dielectric constant is entered). Automatic refer
-
ence delay feature adds the correct electrical length com
-
pensation at the push of a button. Software compensation
for the electrical length difference between reference and
test is always accurate and stable since measurement fre
-
quencies are always synthesized. In addition, the system
compensates reference phase delay for dispersive trans
-
mission media, such as waveguide and microstrip.
Markers: Six independent markers can be used to read
out measurement data. In delta-reference marker mode,
any one marker can be selected as the reference for the
