Measurement Screens
In general all the measurement screens provide either a graphic representation of the measurement
parameter(s) selected (Sweep mode) or a fast changing digital readout (CW mode). The support
screens are designed for entering various settings or saving and recalling test results from the
memory.
Scales can be changed by pressing the UP arrow key to highlight the desired measurement
parameter then press the Scale key repeatedly to select the desired scale. In the case of SWR or RL
there is only one scale on the left, so the Scale key can be used at any time to adjust the
measurement screen’s SWR or Return Loss scale.
Cursors can be used to get measurements anywhere on the displayed trace. Cursors are enabled by
pressing the CRSR key. It is possible to have one or two cursors on the screen at once. Pressing the
CRSR key the first time will enable the first cursor (CRSR A), pressing CRSR again will enable the
second (CRSR B). Cursors can be moved to the desired frequency via the LEFT/RIGHT arrow key. If
both cursors are enabled, pressing the CRSR key will toggle the cursor that is currently selected. The
cursors' FREQUENCY field will be highlighted when selected, allowing you to select the cursor you
wish to move. The LEFT/RIGHT arrow keys will move the selected cursor only.
When both A & B cursors are selected a
CRSR ∆ (differential) reading will appear below the B cursor.
Holding down the LEFT/ RIGHT arrow keys will increase the cursor movement speed.
NOTE: When the cursors are active, if you move them past either end of the displayed trace, the
trace will scroll to reveal data points not previously visible. This is particularly noticeable when the
graph is displayed in narrow format.
Other parameters can be changed by pressing the UP arrow key repeatedly to cycle the highlight to
the desired parameter. Then press the ENTER key to cycle to the desired preset or ENTER may
cause an exit to a setting screen as with FREQ.
