DIAGnostic
DIAGnostic:CHECksum?
DIAGnostic:CHECksum?
performs a checksum operation on Flash Memory.
A returned value of 1 indicates that Flash memory contents are correct. A returned
value of 0 indicates that the Flash Memory is corrupted or has been erased.
value of 0 indicates that the Flash Memory is corrupted or has been erased.

DIAGnostic:CONNect
DIAGnostic:CONNect <source>,<mode>,(@<ch_list>)
configures the
VT1529A/B to verify its measurement paths by measuring either the internal
calibration source or an internal short for all 32 channels. A matching scan list must
be defined, the instrument triggered, and the results read from the FIFO or CVT.

Note
The command DIAG:TEST:REMote:SELFtest? actually performs all of the
verification functions this command provides and in addition includes filter and
scanner tests.

Parameters
Comments
•
The <source> parameter specifies the source to measure. NORMal configures
all inputs to measure user inputs. SHORT specifies the internal calibration short.
SOURce specifies the internal 100 mV calibration source.
SOURce specifies the internal 100 mV calibration source.
•
The <mode> parameter: ALL connects all channels to the specified <source>.
ALT connects channels alternately to the SHORt or the SOURce. When <mode>
is ALT, the <source> parameter specifies which source is connected to the first
channel. For example, when <source> is SHORt, even channels are 0 V, odd
channels are 0.1 V.

•
The <ch_list> parameter specifies which VT1529A/B to configure. Specifying
any channel on the a VT1529A/B configures all channels on the unit.
•
DIAG:CONN NORM,ALL,(@<ch_list>) must be executed to reset units for
normal measurements.
