Vertical Deflection; Dynamic Range At 60/100/200 Mhz; Vertical Deflection; Position Range - Fluke Autoranging CombiScope PM3370B Reference Manual

4 - 16
Settings/procedure:
1 - Apply a 50 MHz (PM3390B/94B), 25 MHz (PM3380B/84B) or 15 MHz
(PM3370B) sine wave signal of 2.4 V(pp into 50Ω) to input CH1 and press
the AUTOSET key.
2 - Use a 50Ω termination. Use the internal termination when avaialble.
3 - Set CH1 to 0.1V/div.
4 - Using the CH1 POS control, shift the sine wave vertically over the screen.
Requirements:
- Verify that top and bottom of the sine-wave signal of 24 divisions in amplitude
can be displayed with no distortion.
Repeat the above settings and procedure for CH2, CH3, and CH4. PM3370B/
80B/90B: check CH2.
4.3.13

Vertical deflection; dynamic range at 60/100/200 MHz

(continuation of 4.3.12)
In this test, the dynamic range of the amplifier is checked at a high frequency.
Settings/procedure:
1 - Apply a 200 MHz (PM3390B/94B), 100 MHz (PM3380B/84B) or 60 MHz
(PM3370B) sine-wave signal of 0.8 V(pp into 50Ω) to input CH1.
2 - Press the AUTOSET key, and set CH1 to 0.1V/div.
3 - Use a 50Ω termination. Use the internal termination when available.
4 - Set the amplitude to exactly 8 divisions.
Requirements:
- Verify that the sine wave of 8 divisions in amplitude is displayed with no distortion.
Repeat the above settings and procedure for CH2, CH3, and CH4.
PM3370B/80B/90B: check CH2.
4.3.14

Vertical deflection; position range

The range of the vertical shift is checked with a sine-wave signal of 8 divisions in
amplitude.
