5. Gain Control
There are three calibrated vertical gain settings available ( X1 ,
X5 , and X10 ), as well as an independent variable gain control.
Enter the GAIN menu and select X5 . Note that X5 is outlined
and the display is amplified. Select X10 . Note that X10 is
outlined and the display is amplified again.
Select variable gain and use the right bezel control to adjust
the gain to the minimum and maximum settings.
Exit the GAIN menu, then enter it again. Note that the vari-
able and X10 gain settings are restored. Exit the GAIN menu.
Adjust the VERT POS control to place the signal on baseline.
6. Select Timing Reference
The factory preset selects a two-line sweep. Note that
pressing the
LINE/BUTTON button will cycle through four
selections: one-line, two-line, one-field, and two-field
sweeps. Return to the two-field sweep.
Press the MAG button. The MAG indicator lights and a
1 S/Div sweep is displayed. Use the HORIZ POS control to
view the magnified display, then turn off the MAG . (See page
3-6 for a list of sweep rates.)
7. Voltage and Timing Cursors
The 1760--Series voltage, timing, and vector cursors can be
used to measure any portion of the displayed signal.
Enter the CURSOR menu (factory preset selects voltage
cursors; VOLT is outlined on screen). The voltage cursors
appear as two dashed horizontal lines: cursor 1 has single
dashes and cursor 2 has double dashes. Use the left and
center bezel controls to adjust the cursors individually, or the
right control to move both cursors by the same amount
( TRACK ) . The voltage difference between the cursors is
displayed as
∆ V . Align a voltage cursor with a signal refer-
ence point and press MAG . The cursor is still at the same
point on the signal (use the HORIZ POS control if needed to
view the cursor).
