Rear Panel
Theory of Operation
REAR PANEL FUNCTIONAL GROUPS
The assemblies
and components mounted
on the instrument rear panel
are
divided into the following
functional groups:
•
HP-IB
Provides
a
digital Interface by which the synthesizer
communicates with other HP-IB equipped
instruments or controllers.
•
Sweep-Related Interface
Lines
Signals that allow the synthesizer to interface with external
devices
(e.g.
X-Y recorders, network
analyzers). An external device can determine the instrument's sweep state, and can stop the
sweep using
STOP SWP IN/OUT. When
the synthesizer is in the external trigger mode, an
exter¬
nal device can initiate
a sweep
using the
EXT TRIGGER INPUT.
• Frequency Standard
Includes the
INT and EXT connectors
and the frequency standard switch. Use this group to select
either the
internal or external
frequency standard, the synthesizer's master timebase.
•
RF Outputs
Include
the AUX
OUTPUT
connector, and, for
option 004
and
005 instruments, the RF OUTPUT
connector.
•
Dedicated Interface Connectors
Interface with the HP
8410B/C
vector network analyzer.
• Fan
Provides instrument
cooling.
•
Line Module
Holds the main line fuse and the line voltage selector cam, and suppresses line transients.
