Qualifier: A user-specified term that can be anystate, nostate, a single pattern
recognizer, range recognizer, or logical combination of pattern and range
recogmzers.
Sequence Levels: There are eight levels available to determine the sequence of
events required for trigger. The trigger term can occur anywhere in the first seven
sequence levels.
Branching: Each sequence level has a branching qualifier. When satisfied, the
analyzer will restart the sequence or branch to another sequence level.
Occurrence Counter= Sequence qualifier may be specified to occur up to 65535
times before advancing to the next level.
Storage Qualification: Each sequence level has a storage qualifier that specifies
the states that are to be stored.
Enable/Disable: Defines
window can be qualified.
a window of post-trigger storage. States stored in this
Prestore: Stores two qualified states that precede states that are stored.
Tagging
State Tagging: Counts the number of qualified states between each stored state.
A measurement can be shown relative to the previous state or relative to trigger.
Maximum count is
4.4 X (10
to the
12th
power).
Time Tagging: Measures the time between stored states, relative to either the
previous state or to the trigger. Maximum time between states is 48 hours.
With tagging on, the acquisition memory is halved; minimum time between states is
60 ns.
Symbols
Pattern Symbols:
A
mnemonic can be defined for the specific bit pattern of a
label. When the data display is SYMBOL, a mnemonic is displayed where the bit
pattern occurs. Bit patterns can include zeros, ones, and don't cares.
Range Symbols: A mnemonic can be defmed covering a range of values. Bit
pattern for lower and upper limits must be defined as a pattern of zeros and ones.
When the data display is SYMBOL, values within the specified range are displayed
as mnemonic + offset from the base of the range.
Number of Pattern and Range Symbols: 200 per HP 1652B/1653B.
Symbols can be down-loaded over RS-232C and HP-IB.
