Root (:) Commands 6
Agilent InfiniiVision 3000 X-Series Oscilloscopes Programmer's Guide 191
:ACTivity
(see page 1138)
Command Syntax
:ACTivity
The :ACTivity command clears the cumulative edge variables for the next
activity query.
Query Syntax
:ACTivity?
The :ACTivity? query returns whether there has been activity (edges) on
the digital channels since the last query, and returns the current logic
levels.
Return Format
<edges>,<levels><NL>
<edges> ::= presence of edges (16-bit integer in NR1 format).
<levels> ::= logical highs or lows (16-bit integer in NR1 format).
bit 0 ::= DIGital 0
bit 15 ::= DIGital 15
See Also • "Introduction to Root (:) Commands" on page 190
• ":POD<n>:THReshold" on page 527
• ":DIGital<d>:THReshold" on page 295
NOTE
Because the :ACTivity? query returns edge activity since the last :ACTivity? query, you must
send this query twice before the edge activity result is valid.
NOTE
A bit = 0 (zero) in the <edges> result indicates that no edges were detected on that channel
(across the specified threshold voltage) since the last query.
A bit = 1 (one) in the <edges> result indicates that edges have been detected on that
channel (across the specified threshold voltage) since the last query.
(The threshold voltage must be set appropriately for the logic levels of the signals being
probed.)
