OUTPUT @ SCOPE terminal (50Ω) Indicates the location and impedance of the
signal output. If the signal does not appear on the oscilloscope, press O. To
disconnect the signal, press Y. You cannot change the impedance while you are in
LEVSINE mode.
•
MORE OPTIONS Opens additional menu items, which are described in detail
under "The MORE OPTIONS Menu."
•
SET TO LAST F Toggles between the current frequency setting and the reference
value of 50 kHz. This option is useful for reverting to the reference to check the
output after you make adjustments at another frequency.
•
MODE Indicates you are in LEVSINE mode. Use the softkey to change modes and
open menus for other calibration modes.
Shortcuts for Setting the Frequency and Voltage
The following three options are available for controlling the sine wave settings:
•
SET TO LAST F toggles between the last frequency used and the reference
frequency of 50 kHz, letting you check the output at the reference after you make
adjustments at a different frequency.
•
MORE OPTIONS lets you use an automatic frequency sweep and lock the voltage
range, if necessary. The following section provides details on this menu.
•
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.
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 CHG Toggles between two settings that control the way the output signal
adjusts to a new frequency. "Jump" 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
