Signal Generator
0.0 Hz that is a result formed by using the frequency (700MHz) output by the
hard function key to subtract the reference value (700MHz). The REF reference
indicator is at an activated status and the Freq Ref Off\On soft function key
is switched to ON (on).
4. Press the RF ON/OFF .
The indicator on the display screen will be changed from RF OFF into RF ON,
and the RF frequency of the RF OUTPUT connector is 700MHz.
5. Press the up arrow key.
It will increase the output frequency by a constant increment value of 1MHz.
The display in the FREQUENCY region is changed into 1.000 000 0MHz that is
a value formed by using the frequency (1MHz) output by the hard
function key to subtract the reference frequency (700MHz), and at the moment,
the frequency of the RF OUTPUT is changed into 701MHz.
6. Pres the Freq Offset soft function key, and input 1MHz.
It will input 1MHz of offset. The FREQUENCY region displays 2.000 000 0MHz.
The value is a value formed by using the frequency (701MHz) output by the
hard function key to subtract the reference frequency (700MHz) and then
adding the offset (1MHz). OFFS (offset) indicator is at activated status. The
frequency of the RF OUTPUT is still 701MHz.
2-2-1-3 Set RF output amplitude
1. Press PRESET .
2. Observe the AMPLITUDE (amplitude) region on the display screen.
The display screen displays the lowest power electric level of the signal
generator. It is a general preset RF output amplitude.
3. Press RF On/Off .
The status of the indicator on the display screen will be changed from RF
