Measurements Data Points
25,000 Data Points 2 to 25,000 points in up to 16 channels
100,000 Data Points 2 to 100,000 points in single channel
Limit Lines
Limit Lines Single or segmented. 2 limit lines per trace. 50 segments per limit line.
Single Limit Readouts Uses interpolation to determine the intersection frequency.
Test Limits Both single and segmented limits can be used for PASS/FAIL testing.
Averaging
Point-by-Point Point-by-point (default), max Averaging = IF Bandwidth/1 Hz
Sweep-by-Sweep Sweep-by-sweep (no limit)
IF Bandwidth 1, 3, 10, 30, 100, 300 Hz; 1, 3, 10, 30, 100, and 300 kHz; 1 MHz
Reference Plane
Line Length or Time Delay The reference planes of a calibration or other normalization can be changed by entering a line length or time
delay.
Dielectric Constants Dielectric constants may be entered for different media so the length entry can be physically meaningful.
Dispersion Modeling Dispersion modeling is used in the cases of microstrip and waveguide to take into account frequency dependent
phase velocities.
Attenuations Attenuations (with frequency slope) and constant phase offsets can be entered to better describe any reference
plane distortions.
De-embedding For more complete reference plane manipulation, the full de-embedding system can also be used.
Measurement Frequency Range
Frequency Range Change Frequency range of the measurement can be narrowed within the calibration range without recalibration.
CW Mode CW mode permits single frequency measurements also without recalibration.
Interpolation Not Activated If interpolation is not activated, the subset frequency range is forced to use calibration frequency points.
Interpolation Activated If interpolation is activated, any frequency range that is a subset of the calibration frequency range can be used,
but there may be some added interpolation error.
Group Delay
Group Delay Aperture Defined as the frequency span over which the phase change is computed at a given frequency point.
Aperture The aperture can be changed without recalibration.
Minimum Aperture The minimum aperture is the frequency range divided by the number of points in calibration and can be
increased to 20 % of the frequency range.
Group Delay Range < 180° of phase change within the aperture
