3.2.2 Effect of the Bandwidth Filter
Low-pass filters reduce the speed of the signal inside the instrument and cause a delay
of the signal on the screen. The delay time depends on the selected filter.
The following table lists the approximate delay of the signal that is caused by various
filters.
Table 3-1: Approximate signal delay dependent on the bandwidth filter
Filter Approx. delay Filter Approx. delay
200 MHz 30.2 ns 500 kHz 9.07 μs
100 MHz 30.7 ns 200 kHz 22.13 μs
50 MHz 138.5 ns 100 kHz 43.87 μs
20 MHz 145 ns 50 kHz 87.47 μs
10 MHz 166.5 ns 20 kHz 218 μs
5 MHz 193 ns 10 kHz 434.7 μs
2 MHz 270.5 ns 5 kHz 869.3 μs
1 MHz 4.71 μs 2 kHz 2.173 ms
1 kHz 4.347 ms
3.3 Horizontal Setup
Horizontal settings, also known as timebase settings, adjust the display in horizontal
direction.
1. To set the timebase and horizontal position, use the [TIME] and [POS] keys.
2. To adjust all horizontal settings, select "Horizontal" in the main menu.
The determining point of an acquisition is the trigger point. Two parameters define the
position of the trigger point: reference point and horizontal position (also known as trig-
ger offset or delay). Using these parameters, you choose the part of the waveform you
want to see: around the trigger, before, or after the trigger.
