Comments

nHandle

SHORT

Session identifier:

●     Board handle is used when communicating with the hardware. The Board handle session identifier is returned by calling GtDio6xInitialize or GtDio6xSetupInitialization.

●     File handle is used when communicating with a file. The File handle session identifier is  returned by calling GtDio6xFileOpen.

lChannelListArraySize

LONG

Used to specify the number of channels to set. This parameter should not be greater than the size of palChannelListArray. If GTDIO6X_ALL_DOMAIN is passed in, then the palChannelListArray parameter can be set to NULL and the settings will be applied to all channels in the Domain.

palChannelListArray

PLONG

Array containing channels numbers that will be set by this function, channels numbers are 0-based and refers to any channel in the Domain. Auxiliary channel numbers begin with 1000.
GX5296: Each GX5296 board has 4 auxiliary channels that support all the Pin Electronics API functions.

GX5961: Each GX5961 board has 4 fully programmable auxiliary channels, and 8 TTL I/O channels. First 4 auxiliary channels may use all the Pin Electronics API.

GX5964: Does not have Auxiliary channels.

nSignal

SHORT

Type of signal to set delay for.

0.    GTDIO6X_SKEW_DELAY_DRIVE: Drive Signal.

1.   GTDIO6X_SKEW_DELAY_SENSE: Input signal to sense low and sense high comparators.

nEdge

SHORT

The signal’s edge to set delay for:

0.   GTDIO6X_SKEW_PROPAGATION_DELAY: Propagation Delay of selected signal.

1.   GTDIO6X_SKEW_DELAY_FALLING_EDGE_ONLY: Falling edge of selected signal.

dDelay

DOUBLE

Returns the amount of delay.

GX5961/ GX5964:

Output Propagation Delay: Output skew delay can be set from 0 ns to +19.375 ns with 0.625 ns resolution.

Input falling edge: Skew delay can be set from -2.5 ns to +2.1875 ns with 0.625 ns resolution.

GX5296:

Output Propagation Delay: Output skew delay can be set from 0 ns to + 4.6875 ns with 19.53 pSec resolution. The propagation delay circuitry adds timing delay to the Propagation Delay and the falling edge in equal amounts. Propagation delay adjustment is typically used for aligning the timing of multiple channels inside a tester.

Output Falling Edge: Output falling edge skew delay can be set from -2.5 ns to +2.1875 ns with 19.53 pSec resolution. The falling edge delay circuitry adds or subtracts timing delay to or from the falling edge while having no effect on the Propagation Delay. Propagation delay adjustment is typically used for removing any pulse width distortion inside a tester.

Input Propagation Delay: Input skew delay can be set from 0 ns to + 4.6875 ns with 19.53 pSec resolution. The propagation delay circuitry adds timing delay to the Propagation Delay and the falling edge in equal amounts. Propagation delay adjustment is typically used for aligning the timing of multiple channels inside a tester.

Input Falling Edge: Input falling edge skew delay can be set from -156.25 pSec to +146.5 pSec with 9.76 pSec resolution. The falling edge delay circuitry adds or subtracts timing delay to or from the falling edge while having no effect on the Propagation Delay. Propagation delay adjustment is typically used for removing any pulse width distortion inside a tester.

pnStatus

PSHORT

Returned status: 0 on success, negative value on failure.
