OPERATING
3-1. INTRODUCTION.
3-2. This section contains operating and programming
instructions for the -hp- Model 3335A Synthesizer/Level
Generator. Included is a description of controls, connectors
and indicators, operating instructions and operator’s main-
tenance. A list of operating features is tabulated in Table
3-1 which.can be used as an index to locate operating infor-
mation.
3-3. PANEL FEATURES.
3-4. Figure 3-2 illustrates and describes the function of
all front and rear panel controls, connectors and in-
dicators. Items requiring additional description are
referenced to paragraphs in the operating instructions.
3-5. OPERATOR'S MAINTENANCE.
3-6. Operators maintenance of the -hp- Model 3335A
Synthesizer/Level Generator is limited to rear panel power
line fuse replacement.
When replacing fuses, always verify the replace-
ment fuse is of the correct amperage and is
FAST-BLO.
3-7. POWER/WARM-UP.
3-8. The Model 3335A Synthesizer/Level Generator
requires a powér source of 100, 120, 220 or 240 V ac,
+ 5%, - 10%, 48 to 66 Hz single phase. The selection of line
voltage and input power fuse is described in Section H,
Paragraph 2-5, PREPARATION FOR USE.
3-9, The 3335A has a two-position power switch, STBY
and ON. It is important that the instrument remain con-
nected to the power source in the STBY mode when not in
use. This supplies power to the crystal oven maintaining a
constant oven temperature thus eliminating the need for a
long warm-up period. When the STBY mode is not used and
power is disconnected from the instrument, allow 30
minutes from the application of external power in the ON
mode for the instrument to warm up.
INSTRUCTIONS
3-10. Modes of Operation.
3-11. There are two manual modes of operation and an
automatic sweep mode of operation for the Model 3335A
Synthesizer/Level Generator. One manual mode is manual
tune operation allowing the user to manually tune any fre-
quency in the 3335A’s range. The other manual mode is the
manual sweep mode which allows the user to manually
sweep the frequency between predetermined end points.
The automatic sweep mode allows the user to initiate a
single sweep or a continuous sweeping output. The auto-
matic sweep modes are remotely programmable through the
HP-IB.
3-12. OPERATING INSTRUCTIONS.
3-13. Operating the Model 3335A Synthesizer/Level
Generator requires programming the operating parameters
by use of front panel keys. These keys are contained in four
major groupings. From left to right across the front panel
the groups are:
