Required Source Characteristics
1. Output frequency and level which meet input specifications
for the 5344S
2. An FM input port with a sensitivity between 1 and
50 MHz/V and bandwidth of DC to 2 MHz (minimum) for
5344S wideband mode or DC to 200 kHz (minimum) for
narrowband mode
3. Any FM input impedance which will satisfy requirement #2
with a 250 ohm resistance in series with FM input port

Operating Characteristics
Instrument Control:
Instrument parameters may be set up in
three ways. The control knob with coarse and fine modes
allows for continuous adjustment of the parameter of interest.
'Auto Lock feature available when 5344S is used with 8350A or 8620C
Option Oil
fUnless limited by output drive capability.
An exact parameter value can be entered through the Data
Entry Keyboard. For incrementing or decrementing frequency
values, the Step Keys (Step Up/Step Down) can be used. The
Step Size is defined by the user.
Bar Meter:
A front panel, 10 segment, center scale bar meter
indicates the frequency correction signal, from FM OUT
connector, being supplied to the signal source.
Operating Modes
CW:
Manual Lock
— Source is manually tuned to within
capture range of desired frequency. Lock is achieved and is
indicated when LOCKED light annunciator turns on. If
source frequency is outside capture range, the FREQ H! or
FREQ LO light turns on.
Auto Lock*
— Source is tuned automatically by the 5344S
via the HP-IB to bring it into lock.
Note: Refer to signal source compatibility chart for
appropriate source.
CF/AF
Sweep (Manual Lock or Auto Lock*):
Performs
a phase continuous locked sweep from CF -1/2AF to
CF+1/2AF in a sweep time defined by the user. Sweeps up to
40 MHz are available, dependent on the source. If source is too
far from desired frequency range, the user must tune source
(Manual Lock) or the 5344S automatically tunes (Auto Lock)
via the HP-IB. The LOCKED light indicates a proper locked
condition. Marker signals are available within the swept range.
START/STOP Sweep (Manual Lock or Auto Lock*):
Performs a phase continuous locked sweep from START
frequency to STOP frequency over a sweep time defined by
the user. Sweeps up to 40 MHz are available dependent on the
source. The STOP frequency must be greater than or equal to
START frequency. If the source frequency is too far from the
desired frequency range, the user must tune (Manual Lock)
source or the 5344S will automatically tune (Auto Lock) via the
HP IB. The LOCKED light indicates a locked sweep condition.
Marker signals are available within the swept range.
Accuracy — CF/AF and START/STOP modes
Start or Stop Frequencies:
1 kHz TYPICAL
Linearity:
±0.05% of sweep with respect to Sweep Out
voltage (TYPICAL)
Resolution:!
Hz for CF, AF, START, and STOP frequencies
Sweep Time:
Available in CF/AF and START/STOP modes.
Continuously adjustable from 10 ms to 100 s. When sweep time
is selected, user may toggle between continuous and single
sweep by pressing the ACQUIRE key. Tne RESET key initiates
a sweep when in single sweep sub-mode.
Marker Frequencies:
Available in
CF/AF
and START/STOP
modes. Up to four frequency markers are settable across the
swept band. Markers are adjustable with the control knob, data
entry keyboard, or step keys to 1 Hz resolution.
Accuracy:
0.3% of sweep width TYPICAL
Marker Output:
Rectangular pulse, -5 volts peak
(TYPICAL) available from the Z-axis Out connector on front
panel. Source impedance approximately 500 ohms.
LOCK/ROLL (Manual Lock or Auto Lock*):
Sweep is
phase-locked by the 5344S to a precise start frequency and
then control is transferred to the sweeper to complete the
sweep The source determines sweep tune, marker frequencies,
and stop frequency
