Hewlett Packard 83522A Plug-In
The Model 83522A is an RF Plug-In
which has been designed
for use with the Model 8350A Sweep Oscillator
. The Model
83522A covers the frequency range of 0.01 to 2.4 GHz. A YIG
is used as the tunable RF frequency source and a
fixed 3.8 GHz Oscillator
is mixed with the YIG Oscillator
generate a 0.01 to 2.4 GHz RF output.
Model 83522A front panel functional controls, pushbuttons,
and the Rotary Pulse Generator
(RPG), are monitored by the
Model 8350A via the RF Plug-In Interface
circuits. The Model
8350A generates a tuning voltage ramp according to the mode
of operation (CW, START/STOP, CF/AF). This voltage ramp is
scaled and offset by the Model 83522A to provide a voltage
ramp which is proportional to the YIG Oscillator
in the Model 83 522A. The Model 83522A then converts the
tuning ramp voltage to a current which drives the YIG
The Model 83522A offers a maximum leveled RF output power of
+13 dBm. Internal (INT), External (EXT), and Power Meter
(MTR) leveling is available as selected by the front panel
pushbuttons. A front panel EXT/MTR ALC input connector and
gain control (CAL) are provided to use with an external
leveling loop. A front panel LED indicates when the RF
output becomes unleveled. The RF output level is controlled
by the Model 83522A RPG, the Model 8350A data entry controls
(keypad and step keys), or through HP-IB control via the
Service and User Manual

INSTRUMENTS COVERED BY MANUAL in Section I.
This manual is divided into eight major sections which
provide the following information:
a. SECTION I, GENERAL INFORMATION, includes a brief
description of the instrument, safety considerations,
specifications, supplemental characteristics, instrument
identification, options available, Accessories
and a list of recommended test equipment.
b. SECTION II, INSTALLATION, provides information for
initial inspection, preparation for use, storage, and shipment.
c. SECTION III, OPERATION, explains the resolution
characteristics of the RF Plug-In
in CW and swept frequency
modes. Operating instructions include a front panel
FREQUENCY CALIBRATION procedure, FM switch parameter
settings, and crystal and power meter leveling instructions.
A description of front and rear panel features and Plug-In
error codes is also given.
d. SECTION IV, PERFORMANCE TESTS, presents procedures
required to verify that performance of the RF Plug-In
accordance with published specifications.
e. SECTION V, ADJUSTMENTS, presents procedures required to
properly adjust and align the Model 83522A
f. SECTION VI, REPLACEABLE PARTS, provides information
required to order all parts and assemblies.
g. SECTION VII, MANUAL BACKDATING CHANGES, provides
backdating information required to make this manual
compatible with earlier shipment configurations.
h. SECTION VIII, SERVICE, provides an overall instrument
block diagram with troubleshooting and repair procedures.
Each assembly within the instrument is covered on a separate
Service Sheet which contains a circuit description,
schematic diagram, component location diagram, and
troubleshooting information to aid in the proper maintenance
of the instrument.
