Display
LCD Dot-matrix type display. Capable of displaying: measured values, control
settings, comparator limits and decisions, list sweep tables, self test messages
and annunciations.
Correction function
Open/short: Eliminates measurement errors due to stray parasitic
impedance in the test fixture.
Load: Improves measurement accuracy by using a calibrated
device as a reference.
List sweep function
A maximum of ten frequencies or test levels can be programmed. Single or
sequential testing can be performed. When Option 4284A/4285A-001 is installed,
dc bias sweep can also be performed.
