[SOURce[1]]:PATTern:APCHange:IBHalf
IAgilentN490xPGAuxIn.BShot (not IVI-compliant)
[SOURce[1]]:PATTern:APCHange:IBHalf ONCE
This command is short for Insert BHalf. It causes the insertion of a number of
instances of pattern B. It is valid only when :APCHange:SOURce is set to INTernal
and :APCHange:MODE is set to ONEShot. It is an event command, and as such has
no query form.
Pattern B is repeated as necessary to reach the next 512-bit boundary in the
memory. So, for example, if pattern B is 4 bits long, it is repeated 128 times. Or if
it is 7 bits long, it is repeated 512 times.
See “How the Serial BERT Uses Alternate Patterns” on page 55 for more
information.
[SOURce[1]]:PATTern:APCHange:MODE[?]
IAgilentN490xPGAuxIn.Mode (not IVI-compliant)
[SOURce[1]]:PATTern:APCHange:MODE <MODE>
[SOURce[1]]:PATTern:APCHange:MODE?
<MODE>: ALTernate | ONEShot | LLEVel | REDGe
ALT | ONES | LLEV | REDG
ALTernate
This command controls the mode of operation of the alternate pattern output. The
query returns the current mode of operation.
