Basic Operation
Configuring the RF Output
4. Press RF On/Off.
The display annunciator has changed from RF OFF to RF ON. The power at the RF OUTPUT connector
is −20 dBm.
5. Press
Incr Set > 10 > dB.
This changes the amplitude increment value to 10 dB.
6. Use the up arrow key to increase the output power by 10 dB.
The AMPLITUDE area displays 10.00 dB, which is the power output by the hardware (-20 dBm plus
10 dBm) minus the reference power (−20 dBm). The power at the RF OUTPUT connector changes to
−10 dBm.
7. Press
Ampl Offset > 10 > dB.
This enters a 10 dB offset. The AMPLITUDE area displays 20.00 dB, which is the power output by the
hardware (−10 dBm) minus the reference power (−20 dBm) plus the offset (10 dB). The OFFS indicator
is activated. The power at the RF OUTPUT connector is still −10 dBm.
Configuring a Swept RF Output
The signal generator has two sweep types: step and list.
NOTE List sweep data cannot be saved within an instrument state, but can be saved to the memory
catalog. For instructions on saving list sweep data, see “Storing Files” on page 69.
During swept RF output, the FREQUENCY and AMPLITUDE areas of the signal generator’s
display are deactivated, depending on what is being swept.
This section provides an explanation of the differences between step sweep and list sweep. You will learn
two ways to configure the signal generator’s RF output to sweep a defined set of frequency and amplitude
points. You will create a step sweep and then you will use these points as the basis for a new list sweep.
Step Sweep
When a step sweep is activated, the signal generator sweeps the RF output based on the values entered for
RF output start and stop frequencies and amplitudes, a number of equally spaced points (steps) to dwell
upon, and the amount of dwell time at each point. The frequency, amplitude, or frequency and amplitude of
the RF output will sweep from the start amplitude/frequency to the stop amplitude/frequency, dwelling at
equally spaced intervals defined by the
# Points softkey value.
Step sweep provides a linear progression through the start-to-stop frequency and/or amplitude values. You
can toggle the direction of the sweep, up or down. When the
Sweep Direction Down Up softkey is set to Up,
