SC300 Oscilloscope Calibration Option
Calibrate the Pulse and Frequency Response on an Oscilloscope 10
10-17
Each option in the Levsine menu is shown below.
• OUTPUT @ SCOPE terminal (50Ω) Shows the location and impedance of the
signal output. If the signal does not show on the oscilloscope, push . To
disconnect the signal, push . You cannot change the impedance while you are in
Levsine mode.
• MORE OPTIONS Opens more menu items, which are given in the “The MORE
OPTIONS Menu” section.
• 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 examine the
output after you make adjustments at A different frequency.
• MODE Shows you are in Levsine mode. Use the softkey to change modes and open
the corresponding menus for the other four calibration modes.
Note
If a question mark shows in the Output Display, then no specifications are available
for the frequency that is used. This will occur at frequencies more than 250 MHz.
Shortcuts to Set the Frequency and Voltage
Three options are available to control the sine wave settings.
• SET TO LAST F Toggles between the last frequency used and the reference
frequency of 50 kHz. This lets you examine 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 subsequent section gives details about this menu.
• The and keys step frequencies up or down to let you quickly access a
new set of frequencies. For example, if the value is 250 kHz, changes it to
300 kHz, and changes it to 200 kHz. For voltage values, and step
through cardinal point values in a 1.2-3-6 sequence.
