As previously written, while in OPERATE Mode two distinct display pages can be
obtained and they allow to control, together with the Status Bar, the full working of the
liear amplifier. To switch back and forth the two display pages, press the [DISPLAY]
key.
[DISPLAY]
The output power, reflected power, supply voltage and supply current are displayed,
other than in numerical form, in graphical form too by means of proper "level bars"
provided with a "peak hold" embedded function (about 1 s) which is useful for better
evaluating the measurements variations.
While in OPERATE Mode the following switchings are possible:
• Input selection – Pressing the [INPUT] key there is a switching between the
two inputs; the same result can be obtained driving the two RELAY inputs
placed on the rear panel of the amplifier itself (by pressing the respective PTT
keys of the two connected transceivers).
• Manual band selection – Pressing the [◄BAND] and [BAND►] keys the
working tuning band can be selected if there is not any CAT setting (CAT =
NONE).
• Antenna switching (one of two) for a given band – Pressing the [ANT] key
there is an antenna switching between the two presets stored for the selected
band and a subsequent variation of the tuner settings.
• Power mode setting – Pressing [POWER] key, the amplifier's power
management is switched between HALF (half power mode) and FULL (full
power mode).
The complete readouts of the early mentioned settings are displayed inside the
Status Bar as shown in the above reproduced page detail.
