HP 1650B - Key

KEY
KEY command/query
Note #b
The KEY command allows you to simulate pressing a specified
front-panel key. Key commands may be sent over the bus in any order
that is legal from the front panel. Be sure the instrument is in a desired
setup before executing the KEY command. Key codes range from 0 to 36
with 99 representing no key (returned at power-up). See Table 6-1 for key
codes.
The external KEY buffer is only two keys deep; therefore, attempting to
send KEY commands too rapidly will cause a KEY buffer overflow error
to be displayed on the HP 1650B/51B screen.
The KEY query returns the key code for the last front- panel key pressed
or the last simulated key press over the bus.
Command Syntax: :SYSTem:KEY -C key-code z-
where:
e key-code z= :: = integer from 0 to 36
Example: OUTPUT XXX;":SYSTEM:KEY 24"
