•
Dual display of rectangular coordinates complex impedance.
R (green) + jX (red) at the ANT (Antenna) feed point.
13.
Z – TX – |Z|Φ
•
Dual display of polar coordinates complex impedance.
|Z| (green) Φ (red) at the TX (Sensor) feed point.
14.
Z – ANT – |Z|Φ
•
Dual display of polar coordinates complex impedance.
|Z| (green) Φ (red) at the ANT (Antenna) feed point.
BAR GRAPHS SETTINGS
To change bar graph settings you have to enter TOP LED BAR or BOTTOM LED BAR menu. We haven't
described MENU system yet, but these two MENU items have shortcuts from the main display screen, so we can
do it a bit later. To enter in by shortcut, you have to go to the EDIT mode by pushing briefly EDIT button and
selecting T-BAR: or B-BAR: icon in STATUS bar. When icon is selected push EDIT button again and you will be
directly moved to the TOP or the BOTTOM LED BAR MENU, depends if you have pushed EDIT button on T-
BAR: or B-BAR: icon respectively.
Bar graph settings for top and bottom bar graph are same, only difference is that bottom bar graph has additional
settings for SWR colors.
1. MODE
•
Changes bar graph drawing mode. DOT draws just one segment of actual value, BAR draws all
segments from left up to actual value.
2. AVG ATTACK/DECAY
•
Sets averaging time constants used for average values (AVG).
Range: 0 – 2000ms, Step: 10ms.
