PERFORMANCE TEST
4.3.22
Horizontal deflection; display modes and trace separation
The correct working of main timebase (MAIN TB), delayed timebase (DELAYED
TIME BASE) and the trace separation is checked.
Test equipment:
Fluke 5500A mode: wavegen, wave sine (Alternative: function generator, PM5136).
Test set-up:
Settings/procedure and requirements:
1
-
Apply a 2 kHz sine-wave signal of 400 mV(pp into 50
Ω
) to input CH1.
2
-
Press the AUTOSET key and set CH1 to 0.1V/div.
3
-
Adjust the generator signal to a trace height of 4 divisions.
4
-
Set MAIN TB to 500
µ
s.
5
-
Press the DTB menu key.
6
-
Set DEL’D TB to ’on’ in the DELAYED TIMEBASE menu.
7
-
Set MAIN TB to ’on’ in the DELAYED TIMEBASE menu.
8
-
Set the DELAYED TIMEBASE to 50.0
µ
s.
9
-
Turn the DELAY control (in the DELAYED TIMEBASE section), and verify
that the intensified part can be shifted horizontally along the MAIN TB
display.
10 -
Operate the TRACK control and check that the DEL’D TB and MAIN TB
display can be shifted so that they do not cover each other.
4.3.23
Horizontal deflection; X deflection
The correct working of the X Y mode (X-DEFL ’on’) is tested.
Test equipment:
Fluke 5500A mode: wavegen, wave sine (Alternative: function generator, PM5136)
