Generating a Frequency Swept Signal
The following procedure explains how to set up the instrument to generate a signal at a constant power
level that sweeps linearly from a set start frequency to a set stop frequency over a set amount of time,
then repeats.
The procedure follows:
1. Press the RAMP button to invoke the Main Ramp menu, then press the RAMP FREQ Start/Stop
menu. Select the “Start Frequency” menu item in the RAMP FREQ menu, and enter the desired
ramp start frequency using either the numeric keypad, Step Up/Step Down buttons, or the rotary
knob.
2. Select the “Stop Frequency” menu item in the RAMP FREQ menu, and enter the desired ramp stop
frequency using either the numeric keypad, Step Up/Step Down buttons, or the rotary knob.
NOTE:
The ramp stop frequency must be set equal to or greater than the ramp start frequency.
3. Select the “Power” menu item in the RAMP FREQ menu, and enter the desired output power level
using either the numeric keypad, Step Up/Step Down buttons, or the rotary knob.
4. Select the “Sweep Time” menu item in the RAMP FREQ menu, and enter the desired ramp sweep
time using either the numeric keypad, Step Up/Step Down buttons, or the rotary knob.
5. Select the “Resolution” menu item in the RAMP FREQ menu, and select the desired resolution
using the Step Up/Step Down buttons.
The resolution setting determines the number of discreet frequency steps that will be included in the
frequency ramp. Three resolutions are available: 401, 801, or 1601. Higher resolution settings will
result in more steps and a finer resolution ramp.
6. If the LED indicator that is above the RF ON button is not lit, press the RF ON button to enable the
signal at the RF output connector. When the signal at the RF output connector is enabled, the LED
indicator that is above the RF ON button is blue.
