5520A-SC300 Option
Calibrating the Pulse and Frequency Response on an Oscilloscope

• The X and D keys step frequencies up or down in amounts that let you
quickly access a new set of frequencies. For example, if the value is 250 kHz, X
changes it to 300 kHz, and D changes it to 200 kHz. For voltage values, X
and D step through cardinal point values in a 1.2-3-6 sequence.
8-103. The MORE OPTIONS Menu
When you select MORE OPTIONS, you open options that give you more control over
the frequency and voltage. To access the MORE OPTIONS menu, press the softkey
under MORE OPTIONS in the Levsine menu.

Each option in the MORE OPTIONS menu is described below.
• FREQ CHANGE Toggles between two settings that control the way the output
signal adjusts to a new frequency. This is the default setting.
“Jump” causes the output signal to jump immediately to a new frequency setting.
“Sweep” causes the signal to sweep through a series of frequency values, over a
range you set. Use the sweep function to watch the signal gradually change over a
given bandwidth and see the point at which its amplitude changes. Details for using
the sweep function are provided under “Sweeping Through a Frequency Range.”
• RATE Used when FREQ CHANGE is set to “sweep” to toggle the sweep speed
between “fast” and “slow.” The slow speed is one tenth the fast speed.
The slow sweep rate lets you watch the frequency change very slowly. After a fast
sweep, you may want to pinpoint a certain frequency with a slow sweep over a
subset of your previous frequency range.
