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 1 MHz markers are available up to
1 GHz. 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 an external 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, 7 0 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 10 dB 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.
1-30. EQUIPMENT REQUIRED BUT NOT
SUPPLIED
1-31. To have a complete operating sweep
oscillator unit, the Model 83522A RF plug-in
must be installed in a Model 8350A Sweep
Oscillator. Refer to Section I1 Installation in this
manual for a detailed description of RF plug-in
installation.
1-32. EQUIPMENT AVAILABLE
1-33. Service Accessories
1-34. A Service Accessory Kit (HP Part No.
08350-60020) is available for servicing the Model
83522A RF Plug-in and the Model 8350A Sweep
Oscillator. HP Part Numbers for the individual
parts of the kit are provided in Table 1-3.
1-35. The Service Accessory Kit includes:
Two 44-pin printed circuit board extenders.
These boards have keyed slots which allow
them to be used in each of the keyed pc
board connectors in the Model 83522A and
in the Model 8350A as well.
