Multiplexed Channels

The 4 channel instruments have 4 channels configured as 2 + 2. This implies, that the channels CH1
and CH2 are multiplexed with the channels CH3 and CH4 to share the same dual channel digitizer.
The Ext.Trig. channel (TRIG VIEW) is multiplexed the same way as CH4.
Multiplexed channels
(CH1 and CH2) or
(CH3 and CH4)
Any other combination
for timebase settings
200s/div to 10 µs/div
5 µs/div to 2 ns/div
Max. Chop freq.
Note 1: At 250 ns/div each of the four channels is acquired in alternated mode.
Note 2: When peak detection is activated the multiplexing is in alternating mode.
