•
VCA/SUM IN, 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; the MAIN OUT key simply
switches the main output on or off.
•
MAN/SYNC is used for manual triggering (when TRIG IN is appropriately set) and for
synchronising two or more generators when suitably connected together. HOLD is used to
manually pause arbitrary waveform output and sweep; the output is held at the level it was at
when 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 waveforms to/from non-
volatile memory; the RECALL key can also be used to directly access the non-volatile stores.
•
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 generators 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.
A diamond beside a screen item indicates that it is selectable; hollow diamonds identify
deselected items and filled diamonds denote selected items. For example, press MODE to get
the screen shown below:
MODE:
♦
continuous
◊
gated
◊
triggered setup…
◊
The filled diamond indicates that the selected mode is
continuous
.
Gated
or
Triggered
modes are selected by pressing the associated soft-key which will make the
diamond beside that item filled and the diamond beside
continuous
hollow. This screen also
illustrates how an ellipsis (three dots following the screen text) indicates that a further screen
follows when that item is selected. In the case of the MODE screen illustrated, pressing the
setup…
soft-key brings up the
TRIGGER SETUP
menu; note that selecting this item does not
change the
continuous/gated/triggered
selection.
Some screen items are marked with a double-headed arrow (a split diamond) when selected to
indicate that the item’s setting can be changed by further presses of the soft-key, by pressing
either cursor key or by using the rotary control. For example, pressing FILTER brings up the
screen shown below.
FILTER SETUP
mode: auto
◊
type: 10MHz eliptic
Repeated presses of the
mode
soft-key will toggle the mode between its two possible settings
of
auto
and
manual
. Similarly, when
type
is selected, repeated presses of the
type
soft-
key (or cursor keys or use of the rotary control) will step the selection through all possible settings
of the filter type.
