EB200 Manual Operation

3.4 Direct keys

Note:
When you press the keys MOD, BW, MGC, SQU, TONE, ATT, AFC and LEV once, the next selection is
activated. The displayed window shows the already changed setting. Thus the unit can be operated
blindfold.

3.4.1 MOD key (modulation modes)

Selection of modulation mode by the + or – function of the key: FM, AM, PULSE, CW, USB, LSB, IQ
When you press this key, the pulldown menu shown below with a number of items for selection is
displayed. When you press the key once, the next selection is activated. In a pulldown menu, the
currently selected modulation mode is shown in inverse video.
When you press the key once again the next item is selected. There is no stop to the toggle function, so
when the end of the menu is reached in either direction the next step leads to the opposite end of the
menu.
The pulldown menu disappears after approx. 2 to 4 seconds or if any other key is pressed.

3.4.2 BW key (bandwidths)

IF bandwidth selection with the + function (larger bandwidths) and – function (smaller bandwidths) of
the key
Just as with modulation modes, the bandwidth selection is shown in a pulldown menu. The currently
selected bandwidth is shown in inverse video.
Stepping through the bandwidth selection stops at the highest and the lowest value.
