PERFORMANCE TEST
4 - 37
Settings/procedure:
1
-
Apply a 50 kHz sine-wave signal of 30 mV(pp into 50
Ω
) to input CH1.
2
-
Press the AUTOSET key and set CH1 to 5 mV.
3
-
Use a 50
Ω
termination. For instruments with switchable 50
Ω
input
impedance it is recommended to make use of this feature (’LZ’ must be
visible in lower part of viewing area).
4
-
Press the DISPLAY menu key and then press the X-DEFL softkey.
5
-
Select ’on’ and ’ch1’ from the X-DEFL menu.
6
-
Press the CH2 ON key and then the CH1 ON key: the result is that CH2 is
on and CH1 off.
7
-
Adjust the input voltage for exactly 6 divisions horizontal deflection.
8
-
Increase the input frequency up to 2 MHz.
Requirements:
-
Verify that the trace width is at least 4.2 divisions over the complete bandwidth
range.
4.3.33
Maximum phase shift between horizontal and vertical deflection
There will be a certain phase shift between the horizontal and vertical amplifier.
The value of this shift is measured here.
Test equipment:
Fluke 5500A mode: wavegen, wave sine (Alternative: function generator, PM 5136).
