Configuring the RF Output
This section provides information on how to create continuous wave and swept RF (page 38) outputs.
It also has information on using a mm-Wave source module to extend the signal generator’s
frequency range (page 53).
Configuring a Continuous Wave RF Output
These procedures demonstrate how to set the following parameters:
• RF output frequency
• frequency reference and frequency offset (page 37)
• RF output amplitude (page 37)
• amplitude reference and amplitude offset (page 38)
Setting the RF Output Frequency
Set the RF output frequency to 700 MHz, and increment or decrement the output frequency in 1 MHz
steps.
1. Return the signal generator to the factory-defined state: Press
Preset.
NOTE You can change the preset condition of the signal generator to a user-defined state. For
these examples, however, use the factory-defined preset state (set the
PresetNormal User softkey
in the Utility menu to Normal).
2. Observe the FREQUENCY area of the display (in the upper left-hand corner).
The value displayed is the maximum specified frequency of the signal generator.
3. Press
RF On/Off.
The
RFOn/Off hardkey must be pressed before the RF signal is available at the
RF OUTPUT connector. The display annunciator changes from RF OFF to RF ON. The maximum
specified frequency should be output at the RF OUTPUT connector (at the signal generator’s
minimum power level).
4. Press
Frequency > 700 > MHz.
The 700 MHz RF frequency should be displayed in the FREQUENCY area of the display and also in
the active entry area.
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 decreases the frequency by the increment value set in the previous step. 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.
