Initial Operation
Initial Operation 4

FREQuency, AMPLitude, OFFSET and MODE keys display screens which permit
their respective parameters to be edited either from the numeric keypad or using the
rotary control/cursor keys.
Numeric keys permit direct entry of a value for the parameter currently selected.
Values are accepted in three formats: integer (
20), floating point (20·0) and
exponential (
2 EXP 1).
For example, to set a new frequency of 50 kHz, press
FREQ followed by 50000
ENTER
or 5 EXP 4 ENTER.
ENTER confirms the numeric entry and changes the generator setting to the new
value.
CE (clear entry) undoes a numeric entry digit by digit. ESCAPE returns a setting
being edited to its last value.
MODULATION, SUM, TRIG IN and SYNC OUT call screens from which the
parameters of those input/outputs can be set, including whether the port is on or off.
SWEEP similarly calls a screen from which all the sweep parameters an be set.
Each channel has a key which directly switches the MAIN OUT of that channel on
and off.
MAN TRIG is used for manual triggering (when TRIG IN is appropriately set) and
for synchronizing two or more generators when suitably connected together.
MAN
HOLD
is used to manually pause arbitrary waveform output and sweep; the output is
held at the level it was at when
MAN HOLD was pressed.
UTILITY gives access to menus for a variety of functions such as remote control
interface set-up, power-up parameters, error message settings and store/recall set-ups
to/from non-volatile memory; the
STORE and RECALL keys can also be used to
directly access the non-volatile stores.
The
INTER CHannel and COPY CHannel keys (multi-channel instruments only)
directly call screens from which channel-to-channel phase locking and set-up
copying can be controlled.
The
SETUP keys (multi-channel instruments only) select the channel to be edited;
the lamp lights beside the channel currently enabled for editing.
Eight soft-keys around the display are used to directly set or select parameters from
the currently displayed menu; their operation is described in more detail in the next
section.
The
STATUS key always returns the display to the default start-up screen which
gives an overview of the generator's status. Pressing
STATUS again returns the
display to the previous screen.
Further explanations will be found in the detailed descriptions of the generator’s
operation.
Principles of Editing
Each screen called up by pressing a front panel key shows parameter value(s) and/or a list
of choices. Parameter values can be edited by using the rotary control in combination
with the left and right arrowed cursor keys, or by direct numeric keyboard entry; choices
are made using the soft-key associated with the screen item to be selected. The examples
which follow assume factory default settings.
