Description
DcotCounterEnhMeasurementMode
DcovCounterEnhMode_Counter
Counter Mode
DcovCounterEnhCounter_Totalize
Totalize Mode – The counter counts up and rolls over on
the 16-bit or 32-bit boundary.
DcovCounterEnhCounter_ClearOnRead
Clear On Read Mode - The counter is cleared at the
beginning of every scan; and the final value of the counter
[the value just before it was cleared] is latched and
returned to the Wavebook/516.
DcovCounterEnhCounter_RollOver
Rollover Mode - The counter continues to count upward,
rolling over on the 16-bit or 32-bit boundary.
DcovCounterEnhCounter_StopOnTop
Stop at the Top Mode - The counter will stop at the top
of its count. The top of the count is FFFF for the
16-bit option and FFFFFFFF for the 32-bit option.
DcovCounterEnhCounter_LatchOnSOS
Selects start of scan. Latches the counter outputs at the
beginning of every scan.
DcovCounterEnhCounter_LatchOnMap
Selects the mapped signal to latch the counter outputs.
This allows the user to know the exact counter value
when an edge is present on another channel.
DcovCounterEnhCounter_DecrementOff
Sets the counter decrement option to “off.”
DcovCounterEnhCounter_DecrementOn
Sets the counter decrement option to “on.”
DcovCounterEnhCounter_CountChan
Selects channel for count.
DcovCounterEnhCounter_CountMap
Selects mapped channel for count.
DcovCounterEnhModeMask_16Bit
Selects 16-Bit counter.
DcovCounterEnhModeMask_32Bit
Selects 32-Bit counter.
DcovCounterEnhModeMaskGatingOff
Selects gating “off.”
DcovCounterEnhModeMaskGatingOn
Selects gating “on.” When “On”, the counter is enabled
when the mapped channel to gate the counter is high.
When the mapped channel is low, the counter is disabled
(but holds the count value).
DcovCounterEnhMode_OFF
Turns the Enhanced Counter Mode “off.”
Enumeration with
Bit-Masking.
The options can be
combined.
DcovCounterEnhMode_Counter
Turns the Enhanced Counter Mode “on.”
