Model 5344A Specifications (Continued)
If source is too far from desired frequency, the user must tune
source (Manual Lock) or the 5344S can automatically tune
(Auto Lock) via the HP-IB. The LOCKED light indicates a
proper locked condition.
Start Frequency
Resolution: I Hz
Accuracy: Equal to counter accuracy
Residual stability: <50 kHz rms TYPICAL
5344S Option 043:
With the 5343A microwave counter
installed, special interface cables can be connected to the
8350A to enhance measurements. The marker frequencies and
stop frequency can be measured by the counter with improved
accuracy (±100 kHz TYPICAL)
Subharmonic/Offset Mode
Mode is selected by rear panel switch and indicated by a
decimal point in far nght of numeric display. Multiplier type
sources (eg., HP 83570A, 83590A, 83592A, 83594A, 83595A,
86290) can be phase locked via the subharmonic frequency
available on the Auxiliary Output connector. The actual output
frequency is displayed on the 5344S while locking to the
subharmonic output.
'Auto Lock feature available when 5344S is used with 8350A ot 86200
Option Oil.
Offset mode is used for sources that generate RF frequencies
by heterodyning a variable oscillator with a fixed oscillator.
When the variable oscillator is available at the Auxiliary Output
(e.g. HP 83592A, 83595A), the 5344S can display the actual
source output frequency, while phase locking to the Auxiliary
Output, after entering the appropriate frequency offset on the
counter. Accuracy is now limited by stability of the fixed
oscillator (<20 kHz rms TYPICAL for 83592A, 83595A).
Subharmonic/Offset mode can be useful for any general
purpose sources used with external multipliers and mixers.
Acquire Function
Acquires a frequency measurement from the counter and
places the value in the numeric display when unlocked.
HP-IB Operation
Remote Programming
Interface:
HP-IB (Hewlett-Packard's implementation of IEEE
Standard 488)
Functions controlled:
All front panel functions with the
exception of the line switch and Auto Lock are programmable.
Shorthand Interface Function Codes:
SHI, AH1, T2,
12,
SRI, RL1, PP0, DC1, DTI, CO, El
Standalone:
The 5344A is connected to the source via
HP IB and acts as the controller. Rear panel switch selectable.
This mode accomplishes Auto Lock.*
Maximum FM (TYPICAL)
Phase lock will be maintained if the maximum FM on source is
not exceeded at the various modulating frequencies.
GENERAL
Z-Axis In:
Accepts the Z-Axis modulation signal from sweeper.
Tied directly to Z-Axis Out for LOCK/ROLL mode. Otherwise
has no effect. Front panel BNC female connector.

NARROWBAND
MODULATING FREQUENCY
Z-Axis Out:
Provides a Z-Axis modulation signal for display
devices. Is generated by the 5344A when in locked sweep
modes (CF/AF or START/STOP) and is a direct-coupied
rectangular pulse of approximately +5.0 volts peak during
retrace. Intensity marker signals are also output through this
connector. At all other times is tied directly to Z Axis in. Front
panel BNC femaie connector.
Sweep In:
Accepts the sweep out signal from the sweeper as
required in LOCK/ROLL mode and ties it directly to the Sweep
Out connector. Otherwise has no effect. Front pane! BNC
female connector.
Sweep Out:
Provides a linear ramp voltage from 0 to 10 volts
synchronous with the swept RF output when in locked sweep
mode (CF/AF or START/STOP). Otherwise, Sweep Out is tied
directly to Sweep In. Front panel BNC female connector.
Sweep Trigger:
Output signal necessary in LOCK/ROLL
mode for connection to Ext Trigger connector on sweeper.
Signal is greater than +2V dc and wider than 2 ms (TYPICAL).
Rear panel BNC female connector.
10 MHz In:
Must be connected to the Freq. Std. Out (10 MHz)
from the rear panel of counter. Rear panel BNC female
connector.
IF In:
Must be connected to the IF Out signal from the rear
panel of the counter. Rear panel BNC femaie connector.
Operating Temperature:
0°C to 50°C
Power Requirements:
