VT1422A Command Reference 279 Chapter 7
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.
Comments •
Returned Value: Returns 1 or 0. The data type is int16.

Usage DIAG:CHEC?
Checksum Flash Memory, return 1
for OK, 0 for corrupted
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.
•
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.
