The 6600A Series
(Figure 1-1) is a family of
microprocessor-based, pushbutton-controlled, GPIB-capable,
broadband signal sources that generate swept and CW
frequencies from 10 MHz to 40 GHz. This ever-expanding
family of sweepers presently consists of 29 models. These 29
models are divided into single-band and multiband sweep
generators, depending upon the number of internal bands used
for frequency-range coverage. Singleband models use one YIG
to span their range, whereas multiband models use
two or more YIGs, or a combination consisting of a YIG (or
YIGs) and a frequency down-converter.
1-4 IDENTIFICATION NUMBER
instruments are assigned a unique six-digit ID
number, such as "205001." The first digit of this ID (2 in
the example) represents the instrument's
year-of-manufacture; the next two (05), its manufacturing
"run;" and the last three (001), its serial number. Each
has two ID numbers assigned,
one for the basic frame and one for the RF deck. The ID
number for the RF deck, which provides primary
identification, is affixed to the outside of the rear panel.
The basic frame ID number appears on the inside of the rear
panel. Please use the primary (outside) serial number when
ordering parts or when corresponding with Customer Service.
The following options are available for the 6600A Series
• Option 1, Rack Mount. Sweep Generator
comes equipped with
mounting ears and chassis track slides that have a 90° tilt
• Option 2, 10 dB Step Attenuator. Sweep Generator
supplied with a front panel or GPIB-programmable 10 dB step
attenuator. Step attenuator has a 70 dB range.
• Option 3, GPEB Interface
. Sweep Generator
is equipped to
operate on the IEEE-488 (IEC-625) Interface
Bus. With Option
3 installed, all front panel pushbuttons except POWER are
bus-programmable. Option 3 may be installed in the field.
• Option 9, Main RF Connector on Rear Panel. Sweep Generator
comes supplied with an SMA female connector installed on the
rear panel rather than on the front panel.
• Option 10, Auxiliary RF Output Connector (Rear Panel).
comes equipped with a second RF connector
(SMA female) installed on the rear panel.
Its output power level is approximately 25 dB below the main
connector power level, and its Maximum Leveled Power
specification is derated by 1.5 dB.
Option 12, RF Output Interface
, Sweep Generator
to Model 661
Controller. Sweep Generator
comes supplied with a rear panel
SMA connector for supplying a 10 dB attenuated RF sample to
the Model 661 Tracking Sweeper Controller.
Option 13, Hardware Interface
to HP 5342 or HP 5343A
. Sweep Generator
comes supplied with a
rear panel BNC connector that allows the HP Counter
used to count the marker frequency (ies).
• Option 14, Data I/O Rear Panel Connector. Sweep Generator
comes supplied with a 37-pin Data I/O connector for
interfacing the Model 661 Tracking Sweeper Controller with
the IEEE-488 Interface
Bus. Sweep Generator
must also have
Option 3 .
