Horizontal Deflection; X Deflection Coefficient Via 'Line' - Fluke Autoranging CombiScope PM3370B Service Manual

PERFORMANCE TEST
Test set-up:
Settings/procedure:
1 - Apply a 1 kHz square-wave signal of 0.1V to input CH1. Output not terminated into 50Ω ('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.

The amplification of the horizontal amplifier via the line trigger signal is checked. Do this test only
when 220V line voltage is available.
Test equipment:
None
Settings/procedure:
1 - Press the AUTOSET key.
2 - Press the DISPLAY menu key.
3 - Press X-DEFL softkey.
4 - Select 'on' and 'line' from the X-DEFL menu.
Requirements:
