—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 defined)
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 filter with optimum noise reduction supports a wide range of frequencies
(from 8 kHz to 200 MHz)
The DLM2000 series has two types of filters, one processed at the input circuit and one based on MATH functions. These filters 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-configure triggers combining analog and logic inputs such as edge, enhanced, and B triggers.
Real time filters
Each channel has 14 low pass filters 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 filters
The input waveform can be filtered using an IIR filter, 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 filters.
