Setting Frequency and Power Levels
Using these procedures, you will learn how to:
• set the RF frequency
• set a frequency reference and a frequency offset
• set the RF output power level
• set an amplitude reference and an amplitude offset
To Set the RF Frequency
1. Turn on power to the signal generator: press the power switch, , so that the green
LED is on. The signal generator will perform an internal check.
2. Press the green
Preset key. The signal generator will return to a set of factory-defined
conditions.
NOTE You can change the preset conditions to a user-defined instrument state.
However, for the purpose of these examples, use the factory-defined preset
state (the Preset Normal User softkey in the Utility menu must be set to Normal).
3. Observe the frequency area of the display (in the upper left-hand corner). It should
display the maximum specified frequency of your signal generator.
4. The signal generator is set to output an RF signal, however the
RF On/Off key must be set
to
On before the RF signal is available at the RF OUTPUT connector. Press RF On/Off.
Notice that the display annunciator changes from
RF OFF to RF ON. The maximum
specified frequency is now being output at the RF OUTPUT connector.
5. Change the frequency to 700 MHz by pressing
Frequency. The current RF frequency is
now displayed in the active entry area of the display. Using the numeric keypad, enter
700 and then press the MHz terminator softkey. The new 700 MHz RF frequency is now
displayed in the frequency area of the display and also in the active entry area.
6. Frequency is still the active function until you press another front panel function key.
Change the frequency again by pressing the up arrow key once. Each press of the up
arrow key increases the frequency by the increment value last set with the
Incr Set key.
The increment value is displayed in the active entry area.
The down arrow works like the up arrow. Practice stepping the frequency up and down
in 1 MHz increments. Use the
Incr Set key to change the increment value to 1 MHz, if
necessary.
7. You can also adjust the RF frequency using the front panel knob. As long as frequency is
the active function (the frequency is displayed in the active entry area), the front panel
knob will increase and decrease the RF frequency. Use the front panel knob to adjust
the frequency back to 700 MHz.
