HP E1459A SCPI Command Reference 57
[SENSe:]EVENt:PORT n:PEDGe?
Returns the value of the Positive Edge Detect Register for all 16 bits of Port n.
Parameters
Comments •
The value returned is in the range of -32768 to +32767. A 0 in any bit position
indicates a positive edge event was not detected for the corresponding bit of
that port; a 1 in any bit position indicates a positive edge event was detected
for the corresponding bit of that port.
•
When an edge event is detected, the Edge Detect Status is set true. Refer to the
[SENSe:]EVENt:PSUM:EDGE? and [SENSe:]EVENt:PORTn:EDGE?
commands.
•
Reading this register for all events that have occurred will clear the event
detector register.
•
*RST Condition: disables the Edge Event.
[SENSe:]EVENt:PORT n:PEDGe:ENABle
Sets the Positive Edge Detection Mask for Port n.
Parameters
Comments •
Each bit enables the corresponding channel positive edge detect mask for Port
n. A 1 means the mask is enabled for that bit, a 0 means the mask is disabled
for that bit.
•
*RST Condition: clears the mask (no enabled bits).
Example EVEN:PORT 1:PEDG:ENAB 32767 Enables Positive Edge Event Detection
on all bits of Port 1
