Reference Plane
The reference planes of a calibration (or other normalization) can be changed by entering a line length. Assumes no loss, flat magnitude, linear phase, and
constant impedance.
Auto Reference Plane Extension Instead of manually entering a line length, this feature automatically adjusts phase shift from the current calibration (or other normalization) to compensate for
external cables (or test fixtures). Assumes no loss, flat magnitude, linear phase, and constant impedance.
Frequency Range Frequency range of the measurement can be narrowed within the calibration range without recalibration.
Group Delay Aperture
Defined as the frequency span over which the phase change is computed at a given frequency point. The aperture can be changed without recalibration. 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 < 180º of phase change within the aperture
Trace Memory A separate memory for each trace can be used to store measurement data for later display. The trace data can be saved and recalled.
Trace Math Complex trace math operations of subtraction, addition, multiplication, or division are provided.
