PERFORMANCE TEST
4.3.31
Horizontal deflection; X deflection coefficient via ’line’
The amplification of the horizontal amplifier via the line trigger signal is checked.
Do this test only when 220V line voltage is available.
Test equipment:
None
Settings/procedure:
1
-
Press the AUTOSET key.
2
-
Press the DISPLAY menu key.
3
-
Press X-DEFL softkey.
4
-
Select ’on’ and ’line’ from the X-DEFL menu.
Requirements:
-
Verify that a horizontal line of 4.3 to 7.7 divisions is displayed when the line
voltage is 220V (rms).
4.3.32
