ALARm?
This query returns alarm status of the 58502A.
Returns a single character, 0 or 1.
A value of 0 indicates alarm is off; a value of 1 indicates alarm is on.
If any of the outputs are not functional or there is an input alarm
( there may be additional internal conditions that generate alarm), 1 is
returned.
If all of the outputs are functional and there is no input alarm, 0 is
returned.
OUTPut:QUEStionable:PACKed?
This query returns the status on each output in a single packed
integer. Each bit is associated with an output channel. The least
significant bit = output 1, next bit = output 2, and so on.
Returns binary weighted decimal
If bit is +0, output signal is present. Hence value of +0 indicates that
all outputs are outputting the source signal. If there was no output
from outputs 2 & 3, the response would be:
+6 (1*0 + 2*1 + 4*1 + 8*0 + ... = 6)
