Situation:
HP 83522A RF Plug-inswith serialprefixeslisted above may experience problemswhen
replacingthe marker assemblyif a compatiblemotherboard and
ALC assemblyarenot
currently installed.
Solution/Action:
Marker assemblieswith HPP/N 8352560092 have new logic circuitrywhich will allow
a new signal
'SQ MOD 2' tobe fed tothe ALC assembly 'SQ MODDelayCircuit' to
reduce Band
0 overshoot. However,this capabilityis only availableif thenew marker
assemblyis used with a revised motherboard and new
ALC assembly.
If a new marker assemblyis installedin a unit with theincorrect motherboard and
ALC
assembly, the -40V supplywill be pulled down and the unit will not function properly.

1-1 6. DESCRIPTION
1-17. 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 oscillator is used as the tunable RF
frequency source and a fixed 3.8 GHz oscillator
is mixed with the YIG oscillator to generate a
0.01 to 2.4 GHz RF output.
1-18. 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,
STARTISTOP, CFIAF). This voltage ramp is
scaled and offset by the Model 83522A to
provide a voltage ramp which is proportional to
the YIG oscillator frequency in the Model
83522A. The Model 83522A then converts the
tuning ramp voltage to a current which drives
the YIG oscillator tuning coil.
1-19. 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 EXTIMTR
ALC input connector and gain control (CAL)
are provided to use with an external leveling

General Information Model
83522A
1-20. Internal crystal referenced frequency
markers are available to provide Z-axis intensity
markers from the Model 8350A rear panel PO2
Z BLANK BNC output or 1 dB amplitude
marker dips on the RF output. Harmonic
markers of 10 and 50 MHz are available up to
2.4 GHz and 1MHz markers are available up to
1GHz. A rear panel BNC connector accepts an
external marker reference frequency. Marker
operation is selected by the front panel controls
or through HP-IB control via the Model 8350A.
1-21. A power sweep function allows the RF
output power to be swept at least 15 dB during
CW mode or swept frequency modes. Power
sweep is selected by the front panel POWER
SWEEP pushbutton. Slope compensation con-
trol is also available by selecting the SLOPE
pushbutton and rotating the Model 83522A
RPG or manipulating the Model 8350A data
entry controls. The power sweep function and
slope compensation may both be selected and
modified through HP-IB control via the Model
8350A.
1-22. The RF output may be internally or
externally amplitude modulated, or externally
frequency modulated. Internal square wave
amplitude modulation frequency is selectable by
a Model 8350A internal jumper to be 1 kHz or
27.8 kHz (for use with the Model 8755 Swept
Amplitude Analyzer). Rear panel BNC con-
nectors accept anexternal
AM or FM frequency.
FM coupling (direct coupled or cross-over) and
sensitivity is selected by an internal configur-
ation switch in the Model 83522A. Refer to
Section 111, Operation, of this manual for
detailed information on the configuration
switch.
1-23. A rear panel IVlGHz signal corresponds
to the RF output frequency. This output voltage
may by used as a reference for pretuning
external equipment in phase locking applica-
tions. (The Model 8410Bl8411A Network
Analyzer utilizes this output in such a
configuration).
1-24. The RF output may be turned off by the
RF ON/OFF pushbutton. RF power on is
indicated by the LED in the center of the
pushbutton. Additionally, in CW mode, the CW
FILTER, when selected, places a capacitor
across the YIG oscillator tuning coil to filter
high frequency noise which would appear at the
RF output. All front panel functions, with the
exception of the FREQ CAL and CAL adjust-
ments, may be set or altered by computer control
via the HP-IB bus connection on the Model
8350A.
1-25. OPTIONS
1-26. Option 002, 70
dB Attenuator
1-27. Option 002 instruments contain a digi-
tally controlled attenuator just before the RF
output. Up to 70 dB of attenuation in 10dB steps
is automatically selected as required to attenuate
the RF output power to the indicated level. The
continuously variable power level function
operates as in a standard instrument with the
data entry controls.
1-28. Option 004, Rear Panel RF Output
1-29. Option 004 instruments have the Type N
RF output connector and the BNC EXTIMTR
ALC input connector on the rear panel instead
of the front panel.

1-39. Model 8755 Frequency Response
Test Set
1-40. The Model 8350A Sweep Oscillator with
the Model 83522A RF Plug-in installed is
compatible with the Model 8755 Frequency
Response Test Set for broadband swept scalar
measurements. The Model 8350A provides
internal 27.8 kHz square wave
AM modulation
of the RF output eliminating unnecessary cable
connections to the Model 8755 or the use of an
external modulator. The Model 8350A can also
produce alternate sweeps through use of the
ALT n function which works in conjunctionwith
the channel switching circuits in the Model
8755C. This permits Channel 1 on the Model
8755C to respond only to the Model 8350A
current state and Channel 2 to the alternate
state. A single cable (HP Part Number 8120-
3174) connects between the Model 8350A rear
panel ALT SWP INTERFACE connector and
the Model 8755C front panelALT SWP INTER-
FACE connector.
1-41. Power Meters and Crystal Detectors
1-42. The RF output can be externally leveled
using the HP Model 432 Power Meter or
negative polarity output crystal detectors. Refer
to Section I11 Operation of this manual for
detailed information on levelingtechniques that
may be used with the Model 8350A/RF Plug-in
combination.
