AUX I/O (Auxiliary Input/Output): Provides for most of
the rear panel BNC connections through a single, 25-pin,
D-type connector. Supports master-slave operation with an
-
other 68XXXB/C synthesizer and allows for a single-cable
interface with the Model 56100A Scalar Network Analyzer
and other Anritsu instruments. For a pinout diagram and de
-
scriptions, see Appendix A, Figure A-2.
SERIAL I/O (Serial Input/Output): Provides access to
RS-232 terminal ports to support service and calibration
functions, and master-slave operations.
IEEE-488 GPIB: Provides input/output connections for the
General Purpose Interface Bus (GPIB). For a pinout dia

OPTIONS
Option 1, Rack Mounting: Rack mount kit containing a
set of track slides (90° tilt capability), mounting ears, and
front panel handles to let the instrument be mounted in a
standard 19-inch equipment rack.
Option 2A, 110 dB Step Attenuator: Adds a 10 dB/step
attenuator with 110 dB range for models having a high-end
frequency of £20 GHz. Rated RF output power is reduced.
Option 2B, 110 dB Step Attenuator: Adds a 10 dB/step
attenuator with 110 dB range for models having a high-end
frequency of £40 GHz. Rated RF output power is reduced.
Option 2C, 90 dB Step Attenuator: Adds a 10 dB/step
attenuator with 90 dB range for models having a high-end
frequency of £50 GHz. Rated RF output power is reduced.
Option 2D, 90 dB Step Attenuator: Adds a 10 dB/step
attenuator with 90 dB range for models having a high-end
frequency of £60 GHz. Rated RF output power is reduced.
Option 2E, 120 dB Electronic Step Attenuator: Adds a
10 dB/step electronic attenuator with a 120 dB range for
models having a high-end frequency of £8.4 GHz. Rated RF
output power is reduced.
Option 2F, 120 dB Electronic Step Attenuator: Adds a
10 dB/step electronic attenuator with a 120 dB range for
models having a high-end frequency of £20 GHz. Rated RF
output power is reduced.
Option 9, Rear Panel RF Output: Moves the RF output
connector to the rear panel.
Option 11, 0.1 Hz Frequency Resolution: Provides fre-
quency resolution of 0.1 Hz.
Option 14, Rack Mounting without Chassis Slides:
Modifies rack mounting hardware to install unit in a console
that has mounting shelves. Includes mounting ears and
front panel handles.
Option 15A, High Power Output: Adds high-power RF
components to the instrument in the 2-20 GHz frequency
range. Option 15A is standard in models having a high-end
frequency that is >40 GHz.
Option 16, High-Stability Time Base: Adds an ovenized,
10 MHz crystal oscillator as a high-stability time base.
Option 17A, Delete Front Panel: Deletes the front panel
for use in remote control applications where a front panel
display and keyboard control are not needed.
Option 18, mmWave Module Bias Output: Provides bias
output for 54000-xWRxx Millimeter Wave Source Modules.
BNC Twinax connectors, rear panel.
Option 19, SCPI Programmability: Adds GPIB command
mnemonics complying with Standard Commands for Pro
-
grammable Instruments (SCPI), Version 1993.0 SCPI pro
-
gramming complies with IEEE 488.2-1987.
Option 22, 0.1 Hz to 10 MHz Audio Frequency: Adds
frequency coverage below 10 MHz. In models having a
high-end frequency of £20 GHz, rated output power is re
-
duced by 1 dB; in models having a high-end frequency of
>20 GHz, rated output power is reduced by 2 dB.
