PERFORMANCE TEST
4 - 15
Settings/procedure:
1
-
Apply a 5 kHz sine wave signal of 600 mV (pp into 50
Ω
) to input CH1, and
press the AUTOSET key.
2
-
Set CH1 to 0.1V/div.
3
-
Adjust the input signal to an amplitude of exactly 6 divisions.
4
-
Lower the frequency to 10 Hz and verify that the displayed amplitude does
not drop below 4.2 divisions.
Requirements:
-
The vertical deflection must be 4.2 divisions or more.
Repeat the above settings and procedure for CH2, CH3, and CH4. PM3370B/
80B/90B: check CH2 and TRIG VIEW via EXT TRIG input.
-
Press the ANALOG key (’ANALOG MODE’ is displayed briefly) to return to
analog mode.
4.3.12
Vertical deflection; dynamic range at 15/25/50 MHz
The oscilloscope must be capable of displaying signal amplitudes that are larger
than the screen. In practice, a low frequency signal with an amplitude equivalent
to 24 divisions must be displayed with no distortion.
Test equipment:
Fluke 5500A mode: levsine (Alternative: constant amplitude sine wave generator
SG 503).
