Query Syntax: DCBM?
Query Response: <mask>
Description: The DCBM command sets the 4-bit binary bit mask used by the
DCRD? query. The mask is entered as the decimal equivalent of
a 4-bit binary number. The binary number represents the masking
of the individual sense lines from M3 (MSB) to M0 (LSB). The
DCBM? query returns the current setting of DCBM.
Other Required Cmds: The FMTU command instructs the generator to use the new
setting. The ALLU command updates hardware to the new setting
and redraws the test image.
Example: DCBM 7 // Set mask to read sense lines
// 0, 1 & 2 only
FMTU // Update hardware to current
// buffer contents
