Cataloging Spectrum Analyzer Memory
When cataloging analyzer memory, you can use “prefix”, “reg,” or “on” to specify the type of
information to be cataloged.
prefix* Catalogs the programs and variables in spectrum analyzer memory according to the
current prefix. (Use Change Prefix or PREFX to change the current prefix.)
reg* Catalogs the contents of the state and trace registers. The center frequency and
span of the state registers are displayed; the title and date of the trace registers are
displayed.
on* Catalogs the on event commands and their status. See the “Cataloging the on event
commands n for more information.
* Catalogs all the programs and variables stored in spectrum analyzer memory, but does
not return the on event commands or the contents of the state and trace registers.
Cataloging the on event commands: When the on event programming commands have not
been set or an instrument preset has been performed, cataloging the on events displays the
status of the on events as UNDEFINED. If the ONEOS, ONSWP, TRMATH, ONMKR, ONSRQ,
and ONPWRUP commands have been set, “CAT on*;” displays their status as ACTIVE. When
ONCYCLE, ONDELAY, or ONTIME have been set, “CAT on*;” returns the information shown in
the following table.

Description of the Catalog On Event Response
The entry for ONCYCLE displays the number of seconds left until the event occurs, followed
by the number of seconds ONCYCLE was set for.
The entry for ONDELAY displays either a positive or negative number. A positive number
indicates the number of seconds left until the event occurs, a negative number indicates the
amount of time that has passed (in seconds) since the event.
The date (in year, month, and day format) and the time (in 24 hour format) that ONTIME is set
for.
