Model 5344S
Operation and Programming
AUTO LOCK Key:
Pressing the AUTO LOCK key when its light is off, places the 5344S in LOCK mode (or
keeps it in LOCK mode if MANUAL LOCK is already in effect) and indicates that thesignal
source will be tuned automatically by the 5344S via HP-IB as necessary to achieve lock.
Pressing the AUTO LOCK key when its light is already on disables LOCK mode and turns
off the AUTO LOCK light.
The "SYSTEM CONTROLLER" switch on the 5344S rear panel HP-IB address switch must
be in the "SYS CONT." position when AUTO LOCK is pressed. Otherwise, an error
indication will be given.
NOTE
If no valid frequency has been entered when LOCK mode is initiated for the first time, a
measurement will be made on the 5342A/43A and the resulting frequency used by the
5344S for the selected mode's FI parameter (CW, CF, START, LOCK/ROLL START).
CONNECTORS
Z AXIS OUT
This connector provides a Z-axis modulation signal for display devices (oscilloscope, X-Y
recorder). Provides a rectangular-5V pulse for selected marker frequencies. At all other
times Z AXIS OUT is tied directly to Z AXIS IN. Z Axis Out is generated by the 5344S
when locked in either locked sweep mode (CF/AF or START/STOP).
SWEEP OUT
This connector provides a linear ramp voltage from zero to 10 volts synchronous with the
RF sweep signal. Sweep Out is generated by the 5344S when locked in either locked sweep
mode. At all other times, SWEEP OUT is tied directly to SWEEP IN.
NOTE
Z AXIS OUT and SWEEP OUT are not generated by the 5344S in CF/AF mode if AF =0 or
in START/STOP mode if START = STOP.
Z AXIS IN
This connector accepts the Z-axis modulation signal from the sweeper. It is tied directly to
Z AXIS OUT within the 5344S except when the 5344S is locked in a locked sweep mode.
Then Z AXIS IN has no effect.
SWEEP IN
This connector accepts the SWEEP OUT signal from the sweeper. It is required in
LOCK/ROLL mode to allow end-of-sweep detection and is then tied directly to SWEEP
OUT within the 5344A. SWEEP IN is also tied to SWEEP OUT at all other times except when
the 5344S is locked in a locked sweep mode (such as CW mode). Then SWEEP IN has no
effect.
LINE OFF/ON
POWER
This switch applies power to the 5344A. If the 5342A (or 5243A) is already on, the counter
will go through its power-up routine following the 5344A power-up routine.
