Basic OperationConfiguring a Swept OutputThe N5183A allows you to use step sweep along with the frequency markers on instruments duringmeasurements (refer to “Using Frequency Markers (N5183A Only)” on page 55).NOTEThe N5183A does not support the 8757 system interface.Figure 3-6Sweep SoftkeysFor details on each key, use key helpas described on page 42.Dwell Time = the time that the signal is settled and you can makea measurement before the sweep moves to the next point.(Point to point time is the sum of the value set for the dwell plusprocessing time, switching time, and settling time.)Step Sweep and List Sweep dwell times are set independently.Lin = steps equally spaced over the sweep; the output changeslinearly.Log = step spacing increases logarithmically over the sweep; theoutput changes exponentially.N5183A Only: Opens the frequency marker menu. See page 55.(The N5183A does not support Agilent 8757 the system interface.)Example: Configuring a Continuous, Linear Step SweepOutput:A signal that continuously sweeps from 500 to 600 MHz and from −20 to 0 dBm, with a dwell timeof 500 ms at each of six equally−spaced points.1. Preset the instrument and open the Sweep/List menu: Press Preset > SWEEP.Because continuous is the default sweep repeat selection, and linear is the default step spacingselection, you do not need to set these parameters.2. Open the step sweep menu: Press Configure Step Sweep.3. Set the following parameters:Start frequency 500 MHz:Stop frequency 600 MHz:Amplitude at the beginning of the sweep, −20 dBm:Amplitude at the end of the sweep, 0 dBm:Press Freq Start > 500 > MHzPress Freq Stop > 600 > MHzPress Amptd Start > −20 > dBmPress Amptd Stop > 0 > dBm.6 sweep points: Press # Points > 6 > EnterDwell time at each point, 500 milliseconds:Press More > Step Dwell > 500 > msec4. Sweep both frequency and amplitude: Press Return > Return > Sweep > Freq Off On > Amptd Off On.A continuous sweep begins, from the start frequency/amplitude to the stop frequency/amplitude.The SWEEP annunciator displays, and sweep progress is shown in the frequency display, theamplitude display, and the progress bar.5. Turn the RF output on: Press RF On/Off.52 Agilent N5161A/62A/81A/82A/83A MXG Signal Generators User’s Guide
