Fundamental Operation
Configuring the RF Output
Chapter 2 21
5. Press
Frequency > Incr Set > 1 > MHz.
This changes the frequency increment value to 1 MHz.
6. Press the up arrow key.
Each press of the up arrow key increases the frequency by the increment value last set
with the
Incr Set hardkey. The increment value is displayed in the active entry area.
7. The down arrow works like the up arrow. Practice stepping the frequency up and down in 1
MHz increments.
You can also adjust the RF output frequency using the knob. As long as frequency is the
active function (the frequency is displayed in the active entry area), the knob will increase
and decrease the RF output frequency.
8. Use the knob to adjust the frequency back to 700 MHz.
Setting the Frequency Reference and Frequency Offset
The following procedure sets the RF output frequency as a reference frequency to which all
other frequency parameters are relative. The frequency initially shown on the display will be
0.00 Hz (the frequency output by the hardware minus the reference frequency). Although the
display changes, the frequency output does not change. Any subsequent frequency changes
are shown as incremental or decremental to 0 Hz.
1. Press
Preset.
2. Press
Frequency > 700 > MHz.
3. Press
Freq Ref Set.
This activates the frequency reference mode and sets the current output frequency
(700 MHz) as the reference value. The frequency displayed is 0.00 Hz (the frequency
output by the hardware, 700 MHz, minus the reference value, 700 MHz). The REF indicator
is activated and the
Freq Ref Off On softkey has toggled to On.
4. Press
RF On/Off.
The display annunciator has changed from RF OFF to RF ON. The RF frequency at the
RF OUTPUT connector is 700 MHz.
5. Press
Frequency > Incr Set > 1 > MHz.
This changes the frequency increment value to 1 MHz.
