Boolean Parameters
Boolean parameters represent a single binary condition that is
either true or false. The 1256 accepts "OFF" or "0" for a false
condition. The 1256 accepts "ON" or "1" for a true condition. The
following command uses a boolean parameter:
[:ROUTe]
:MONitor
[:STATe] { OFF | ON | 0 | 1 }
The following commands turn the monitor OFF:
ROUTE:MONITOR:STATE OFF
ROUTE:MONITOR:STATE
0
MON
OFF
MON
0
The following commands turn the monitor ON
ROUTE:MONITOR:STATE ON
ROUT:MON:STAT
ON
MON
1
When Boolean parameters are queried, the 1256 always replies

“ON” and “OFF” are NOT returned in the reply to
ROUTE:MONITOR:STATE?, or any other query.
