PERFORMANCE TEST
4 - 23
Requirements
-
Verify that the visible signal delay is at least 15 ns (3 divisions).
4.3.20
Vertical deflection; base line instability
In the following test, several adjustments of balance, offset and jump, are
checked.
Test equipment
None
Settings/procedure and requirements:
1
-
Press the AUTOSET key (no input signal) and set CH1 to 5V/div.
2
-
Use the CH1 POS control to position the trace in the vertical middle of the
screen.
3
-
Press both CH1 AMPL keys simultaneously to select the VARiable mode.
The readout changes to 5.00V. The input sensitivity can be adjusted now
in very fine steps between 2 mV and 12.5V/div.
4
-
Press the ’V’ key and verify that the base line jump is not more than
0.2 divisions between 5.00V to 12.5V/div.
5
-
Press the ’mV’ key and verify that the base line jump is not more than
0.2 divisions between 12.5V/div to 5 mV/div.
6
-
Press the ON keys of CH2 and CH1; CH2 is now on and CH1 is off.
7
-
Using the CH2 POS control, position the trace in the vertical middle of the
screen.
8
-
Press both CH2 AMPL keys simultaneously to select the VARiable mode.
The readout changes to 5.00V. The input sensitivity can be adjusted now
in very fine steps between 2 mV and 12.5V/div.
