Model 5344S
Operation and Programming
NOTE
The LOCKED, FREQ HI and FREQ LO indicators and the meter are not
active unless the 5344S is in either MANUAL or AUTO LOCK mode. The
METER is not active unless the 5344S is LOCKED and the LOCKED lampis
on.
FREQ HI/FREQ LO
When the input signal is not locked, these indicators show its position relative to the
desired frequency. This information should be used to tune the signal source to achieve
Manual Lock (see Manual Lock Mode Restrictions
Table 3-2).
LOCKED
Indicates that the input signal of the 5342A/43A counter is locked to the frequency (CW or
swept) entered on the 5344A keyboard.
RMT
When lit, shows that the 5344A has been selected for HP-IB programming. See Remote
Programming Via the HP-IB, paragraph 3-138.
TALK/LSN
These indicators show the selected 5344A HP-IB status. The TALK light indicates that the
5344A is the selected Talker on the HP-IB. This occurs only during Auto Lock and serial
polls when the 5344A is being accessed remotely. The LSN light indicates that the 5344A is
currently addressed to listen on the HP-IB. This never occurs in Auto Lock mode.
CONT
The CONT light indicates that the 5344S in the SYSTEM CONTROLLER mode (rear panel
switch is in the SYS CONT position), With the switch in the SYS CONT position, the Auto
Lock mode of the 5344S is enabled (See Auto Lock Key). No other HP-IB system controller
can be on the bus when the 5344S is in this mode.
FUNCTION KEYS
MODE
MODE cycles (scrolls) through the mode selection (CW, CF/AF, START/STOP, LOCK/
ROLL). Each time the MODE key is pressed, the mode advances one function. The
appropriate mode indicator is turned on, and the FI key is lit. The 5344A parameter
associated with FI for the newly selected mode is displayed.
FI
Selects the first mode parameter (CW, CF, START, LOCK/ROLL START) for display/
change.
F2
Selects the second mode parameter (AF, STOP) for display change. F2 is ignored in CW
mode and in LOCK/ROLL is used only to invoke a special diagnostics mode. See
Table 8-9
for diagnostics.
SWP TIME
Selects the SWEEP TIME parameter for display/change. When SWEEP TIME is selected, it
may also be used to toggle the sweep mode between SINGLE and CONTINUOUS by
pressing the ACQUIRE key. In CONTINUOUS sweep, the 5344S initiates a new sweep
immediately after the previous sweep ends. In SINGLE sweep, the 5344S waits for RESET to
be pressed or a change in any sweep parameter before initiating a sweep. SINGLE sweep
sub-mode is indicated by S.S. being displayed in the two leftmost digit positions of the
5344A display whenever SWEEP TIME is selected.
