—Trigger function example—
•A to B(n) trigger
Example: Trigger on the 7th edge of signal on B. This is effective for
measurements with shifted timing, such as non-standard
video signal vertical/horizontal periods or motor reference
position pulses and drive pulses.

•Serial pattern trigger (user dened)
Example: Trigger on an arbitrarily set pattern of up to 128 bits. This
is effective for detecting ID/Data and other portions of
proprietary communication formats.

Real time lter with optimum noise reduction supports a wide range of frequencies (from 8 kHz to 200 MHz)
The DLM2000 series has two types of lters, one processed at the input circuit and one based on MATH functions. These lters are effective
for rejecting unwanted signals, allowing observation of only the desired bandwidths.
Trigger Function capturing combined analog/digital complex waveforms
The DLM2000 series comes with a variety of easy-to-congure triggers combining analog and logic inputs such as edge, enhanced, and B triggers.
Real time lters
Each channel has 14 low pass lters available from 8 kHz to
200 MHz. Waveforms of limited bandwidths are stored in internal
memory.
Cutoff frequencies: 200 MHz, 100 MHz, 20 MHz, 10 MHz, 5 MHz,
2 MHz, 1 MHz, 500 kHz, 250 kHz, 125 kHz,
62.5 kHz, 32 kHz, 16 kHz, and 8 kHz

Computed digital lters
The input waveform can be ltered using an IIR lter, which is a
MATH function. Filtered waveforms can be displayed at the same
time as the input waveform for comparison. You can select low
pass or high pass lters.
