OPTION U01
Option U01 is a firmware upgrade that provides additional 
capabilities as follows:
Limit Lines and Patterns
Limits:  Up to two limits can be displayed together. 
  Lines are defined by dB value, Patterns are 
  created as files by PSA-Manager and loaded 
  from memory (999 files maximum).
Comparator:  Comparison of trace or trace segment with 
  limits (above/below/between/outside) can  
  generate trigger signal, pulse, or audio alert.
Data Logging
Data Types:  Peak level, Centre Level, Full Trace or Screen 
  Image.
Data Entries:  Up to 25,000 entries per file (2500 for Images).
Trigger Source:  Entries can be made in response to Manual 
  Trigger key, External Trigger, Internal Timer  
  (2s to 100m per entry) or Limits Comparator.
Sweep Trigger
Source:  External Trigger or Limits Comparator.
Offsets and Compensation Tables
Fixed Offsets:  Compensation for external gain or attenuation 
  from -50.0dB to +50.0dB.
75 Ohm:  Compensation for signals from a 75W source.
Tables:  Compensation for variations of level with 
  frequency for antennae or transducers. Tables 
  are created as files by PSA-Manager and  
  loaded from memory (999 files maximum).
Custom Presets
Enables rapid switching between setups for repetitive testing.
View on PC
Enables the screen of the spectrum analyzer to be sent to a PC via 
USB and displayed at a user-defined size.
