Pilot Tones).
Another switch selects the bar mode or the dot mode.
This display is composed of 14 green leds and 6 red leds; in the 100%
mode we will have a 100 KHz full scale (75KHz at the first red led) with
a span of 5 KHz/led and in the 10% mode a span of 0.5 KHz/led.
2.7 ANAMETER
This circuit is composed of two pcb’s and a meter placed on the right
side of the front panel (6 Photo 1).
It measures and displays the various parameters of the exciter: audio
input levels, internal voltages and currents, direct and reflected power
and varicap voltage.
Each type of measurement is indicated by an appropriate led.
These measures are performed using the various scales available on the
instrument:
MEASURE SCALE FULL SCALE
Voltages V 30V
Currents A 6A
Forward Pwr W 50W
Reflected Pwr W 10W
This circuit also features a red UNLOCK led (14 Fig.1A, 10 Fig.1B), and
red REMOTE led (13 Fig.1A, 9 Fig.1B), controlled by the Main Card and
a red SWR led (12 Fig.1A, 8 FIg.1B) controlled by the power supply.
In addition there are: a green power led (16 Fig.1A, 12 Fig.1B), a power
output PWR ADJ trimmer (21 Fig.1A, 17 Fig.1B) and the mains supply switch
(17 Fig.1A, 13 Fig.1B).
