Trigger system
MIL-STD-1553 (optional)
I²S/LJ/RJ/TDM (optional)
Parallel
Mixed Domain Oscilloscopes — MDO4000B Series
Trigger on Sync, Word Type ³ (Command, Status, Data), Command Word (set RT Address, T/R, Sub-address/Mode, Data Word
Count/Mode Code, and Parity individually), Status Word (set RT Address, Message Error, Instrumentation, Service Request Bit,
Broadcast Command Received, Busy, Subsystem Flag, Dynamic Bus Control Acceptance (DBCA), Terminal Flag, and Parity
individually), Data Word (user-specified 16-bit data value), Error (Sync, Parity, Manchester, Non-contiguous data), Idle Time
(minimum time selectable from 2 µs to 100 µs; maximum time selectable from 2 µs to 100 µs; trigger on < minimum, > maximum,
inside range, outside range). RT Address can be further specified to trigger on =, ≠, <, >, ≤, ≥ a particular value, or inside or
outside of a range.
Trigger on Word Select, Frame Sync, or Data. Data can be further specified to trigger on ≤, <, =, >, ≥, ≠ a specific data value, or
inside or outside of a range. Maximum data rate for I²S/LJ/RJ is 12.5 Mb/s. Maximum data rate for TDM is 25 Mb/s.
Trigger on a parallel bus data value. Parallel bus can be from 1 to 20 bits (from the digital and analog channels) in size. Binary and
Hex radices are supported.
Acquisition system
Acquisition Modes
Sample
Peak Detect
Averaging
Envelope
Hi Res
Roll
Acquire sampled values.
Captures glitches as narrow as 800 ps (1 GHz models) or 1.6 ns (≤500 MHz models) at all sweep speeds
From 2 to 512 waveforms included in average.
Min-max envelope reflecting Peak Detect data over multiple acquisitions.
Real-time boxcar averaging reduces random noise and increases vertical resolution.
Scrolls waveforms right to left across the screen at sweep speeds slower than or equal to 40 ms/div.
Waveform measurements
Cursors
Waveform and Screen.
Automatic measurements (time
domain)
29, of which up to eight can be displayed on-screen at any one time. Measurements include: Period, Frequency, Delay, Rise Time,
Fall Time, Positive Duty Cycle, Negative Duty Cycle, Positive Pulse Width, Negative Pulse Width, Burst Width, Phase, Positive
Overshoot, Negative Overshoot, Peak to Peak, Amplitude, High, Low, Max, Min, Mean, Cycle Mean, RMS, Cycle RMS, Positive
Pulse Count, Negative Pulse Count, Rising Edge Count, Falling Edge Count, Area and Cycle Area.
Automatic measurements
(frequency domain)
3, of which one can be displayed on-screen at any one time. Measurements include Channel Power, Adjacent Channel Power
Ratio (ACPR), and Occupied Bandwidth (OBW)
Measurement statistics
Mean, Min, Max, Standard Deviation.
Reference levels
User-definable reference levels for automatic measurements can be specified in either percent or units.
Gating
Isolate the specific occurrence within an acquisition to take measurements on, using either the screen, or waveform cursors.
Waveform histogram
A waveform histogram provides an array of data values representing the total number of hits inside of a user-defined region of the
display. A waveform histogram is both a visual graph of the hit distribution as well as a numeric array of values that can be
measured.
Sources - Channel 1, Channel 2, Channel 3, Channel 4, Ref 1, Ref 2, Ref 3, Ref 4, Math
Types - Vertical, Horizontal
Waveform histogram
measurements
Waveform Count, Hits in Box, Peak Hits, Median, Max, Min, Peak-to-Peak, Mean, Standard Deviation, Sigma 1, Sigma 2, Sigma 3
