When to Adjust the Oscilloscope Display

The oscilloscope display normally does not require adjustment. However, when it is obvious that the display is out of adjustment, use this optional procedure.

	In this procedure, you will make adjustments using two display patterns.
Table 4-3
	Equipment Required to Adjust the Oscilloscope Display
	Equipment	Critical Specifications	Recommended Model/Part
	Digital multimeter	Accuracy ±0.05,% 1 mV resolution	Agilent 34401A

1Connect the digital multimeter to the end of R901, located closest to the fuse, as shown in Figure 4-3.

2Adjust +B.ADJ for +14.00 V.

In the remainder of this procedure, you will make adjustments to:

V.HOLD	(vertical hold)
INTENSITY	(intensity control on oscilloscope front panel)
H.HOLD	(horizontal hold)
FOCUS
V.LIN	(vertical linearity)
V.SIZE	(vertical size)

3Adjust V.HOLD (vertical hold) for vertical synchronization.

4Set the INTENSITY control (lower-left on the front panel) to approximately 50%.

Do not adjust Sub Bri or Cont controls

Do not adjust the SUB BRT (sub bright) or CONTRAST Controls. These controls are preset at the factory to assure the correct number of display grayscales.
