PERFORMANCE TEST
4 - 35
Requirements:
-
Verify that the jitter of the DEL’D TB is not more than 0.4 divisions (1 part per
25000).
4.3.30
Horizontal deflection; X deflection coefficient via CH1
The amplification of the horizontal amplifier via the vertical input amplifier is
checked.
Test equipment:
Fluke 5500A mode: volt (Alternative: Square-wave calibration generator PG 506).
Test set-up:
Settings/procedure:
1
-
Apply a 1 kHz square-wave signal of 0.1V to input CH1. Output not
terminated into 50
Ω
(’LZ’ must not appear in lower part of viewing area).
2
-
Press the AUTOSET key.
3
-
Set CH1 to 20 mV and DC coupled input.
4
-
Press the DISPLAY menu key.
5
-
Press X-DEFL softkey.
6
-
Select ’on’ and ’ch1’ from the X-DEFL menu.
7
-
Press the CH2 ON key and then the CH1 ON key; the result is that CH2 is
on and CH1 is off.
Requirements:
-
Verify that two dots with a horizontal distance of 4.7 ... 5.3 divisions are
displayed.
