Extended Features - Option U01
Option U01 is a firmware upgrade that increases the capabilities of the PSA series 3 to include the following features:
Triggered sweep
The standard sweep modes of continuous repeat and single shot can be extended to include triggered sweeps from an external signal or internal limits comparison.
Limit patterns and limit comparator
Limit lines and patterns can be defined which can be simply visual aids or create automatic actions. Zone restriction can be applied. A single or dual-line limits comparator can be used to generate audible warnings, output signals, or to freeze or log the trace.
Offsets and compensation tables
The reference level, graticule, and marker readouts can be set to compensate for external attenuation or gain to a resolution of 0.1dB. Compensation can also be added for signals emanating from a 75W source. Tables can be loaded that compensate for variations of level with frequency for specific antennae or transducers. The tables can contain up to 100 points and are linearly interpolated between points.
