Modei 5344S
Operation and Programming
UP
Increments the currently selected frequency parameter by the current Step Size fSS).
DN
Decrements the currently selected frequency parameter by the current Step Size (SS).
The UP and DN commands may only be used to change frequency parameters including the
Markers.
The 5344S will ignore any attempt to increment a time parameter such as Sweep Time.
To increment a parameter not currently selected, specify the parameter followed by the UP or DN
command, such as:
CWUP
CFDN
DFUP
FBDN
FAUP
SPDN
SRUP
LRDN
M4DN
When incrementing the different parameters, there is a possibility of incrementing beyond the
5344S lock range. If this occurs the 5344A will display Err 01, and if the RM1 command is used a
Service Request will be generated. The signal source must be tuned manually or over the HP-IB to
within the 5344S lock range.
RESET
RS (RT)
Restarts the locking algorithm. RS will not return the 5344S to local. RT is the same as RS.

MANUAL LOCK
LK 1/0
Sets Manual Lock ON or OFF. The LK command may be part of a command string or placed on a
separate line.
Sending the LK 1 command does not guarantee the 5344S will lock. LK1 tells the 5344S to make an
attempt to lock. If the signal source is within the lock range. Lock will be achieved. If not,the5344A
will light the FREQ HI or FREQ LO annunciator. The signal source must be tuned manually or over
the HP-IB if possible.
Auto Lock cannot be remotely programmed.
