Model 5344S
Operation and Programming
ACQUIRE Key:
5344S frequency parameters may be changed by acquiring them from the 5342A/43A
counter. This is accomplished by pressing ACQUIRE following the selection of the desired
parameter. If the 5344S is not locked, an automatic measurement is performed on the
5342A/43A and the result entered in the 5344S display and used to update the selected
parameter, if the 5344S is locked, the value of the FI parameter of the selected mode is
taken as the new parameter and is immediately reflected in the lock operation. Note that
SWEEP TIME, AF, and FREQUENCY MULTIPLIER may not be acquired. (When SWEEP
TIME is selected, the ACQUIRE key is used to toggle the state of the sweep submode from
CONTINUOUS to SINGLE or vice versa.)
increment/Decrement Keys:
(Up arrow O- Down arrow O
>
Pressing the increment (or decrement) key results in the selected STEP SIZE being added
to (or subtracted from) the currently selected parameter. The 5344S display is updated,
and if the 5344S is in LOCK mode, the new parameter is immediately reflected in the lock
operation. The increment and decrement keys may not be used to change SWEEP Tl ME or
FREQUENCY MULTIPLIER.
Tuning Knob (RPC):
The tuning knob may also be used to adjust all 5344S parameters except FREQUENCY
MULTIPLIER. Turning the knob clockwise increases the value of the parameter, and
turning the knob counter-clockwise decreases the value. The 5344S display is updated,
and, if the 5344S is in LOCK mode, the new value of the parameter is reflected immediately
in the lock operation. The rate of change in the value being adjusted with the tuning knob
is affected by the selected state of the FINE/COARSE key and the rate at which the knob is
being turned.
HNE/COARSE Key
Pressing the FINE/COARSE key toggles the state of the FINE/COARSE indicator light (in
the key). When the light is turned off, tuning knob adjustments are relatively coarse,
allowing rapid changes in parameter values. When the light is on, adjustments are slower,
allowing easier fine-tuning. The FINE/COARSE key is operational at any time except when
the 5344S is in REMOTE HP-IB operation.
RESET Key:
The RESET key has three effects:
1
.
|f the 5344S is in REMOTE HP-IB operation, the RESET key returns the 5344S to
LOCAL mode, restoring control to the front panel. (Note that the RESET key is
ignored if a "LOCAL LOCKOUT" HP-IB
command has been received by the
5344A).
2.
If the 5344S is in LOCK mode but not in REMOTE HP-IB operation, RESET restarts the
locking algorithm.
3.
If the 5344S is LOCKED, in a sweep mode (CF/AF, START/STOP, LOCK/ROLL), and
the single sweep sub-mode has been selected, pressing RESET initiates a new sweep.
MANUAL LOCK Key:
Pressing the MANUAL LOCK key when its light is off, places the 5344S in LOCK mode (or
keeps it in LOCK mode if AUTO LOCK is already in effect) and indicates that the signal
source may need to be tuned to achieve lock. Pressing the MANUAL LOCK key when its
light is already on disables LOCK mode and turns off the MANUAL LOCK indicator light.
