Tektronix 5 Series Mixed Signal Oscilloscope (MSO54/56/58)

Adjust horizontal (time base), vertical (scale, position), and trigger parameters;

Stable display waveform (optimizing the vertical scale of all active waveforms in stacking mode and evenly distributing waveforms in stacking mode).

Note: AutoSet ignores mathematics, reference, and bus waveforms, and signals with frequencies<40 Hz will be judged as "no signal".

(2) Collection mode selection

By double clicking the "Acquisition" badge, the following modes can be selected:

Applicable scenario characteristics of the mode

Sample: Conventional signal acquisition retains the first sample of each acquisition interval without post-processing

Peak Detection captures high-frequency spikes and alternates between narrow pulses to preserve the highest/lowest samples of adjacent acquisition intervals

High Res high-precision measurement, low-noise scene based on sampling rate FIR filtering, suppresses aliasing, ensures ≥ 12 bit vertical resolution, supports FastAcq

Envelope observes the range of signal changes, captures the extreme values of multiple collected signals, and displays the envelope waveform

Average reduces the average waveform of random noise collected multiple times, and the average frequency can be set

FastAcq captures transient events to reduce acquisition dead time, supports intensity display (reflecting signal frequency), and can choose color palettes such as "Temperature" and "Spectral"

(3) Trigger type and configuration

Trigger is used to define when to start collecting waveforms. The 5 series supports a variety of trigger types, including:

Edge trigger (basic):

Trigger source: any analog/digital channel, mathematical/reference waveform;

Slope: rising edge, falling edge, arbitrary edge;

Level: Double click the "Level" knob to set it, or press the knob to automatically set it to 50% of the signal peak to peak value;

Coupling: DC (transmitting all signals), HF Reject (attenuation>50 kHz signals), LF Reject (attenuation<50 kHz signals), Noise Reject (increasing hysteresis, anti noise).

Pulse width trigger:

Trigger conditions: Pulse width<,>,=, ≠ set value, or within/outside the specified range;

Polarity: positive pulse, negative pulse, any polarity;

Application scenario: Narrow pulse and wide pulse fault detection in digital logic.

Bus trigger:

Prerequisite: Corresponding buses (such as CAN, I2C) have been added;

Configuration steps:

Click on "Add New Bus" → select the bus type (such as CAN);

Set bus parameters (such as CAN baud rate, signal source, threshold);

Double click the "Trigger" badge ->select "Trigger Type>Bus" ->select the trigger bus (such as Bus1);

Set triggering conditions (such as CAN ID, data bytes, frame type).

Timing trigger (A&B events):

Function: After triggering event A, data collection will only be initiated upon detecting event B;

to configure:

Select 'Trigger Type>Sequence';

Configure event A (such as Ch1 rising edge);

Configure event B (such as Ch2 pulse width>100 ns);

Set trigger logic: trigger the first B event (with a delay time that can be set), or the Nth B event.

2. Measurement and analysis functions

(1) Basic measurement operation

Add measurement: Click on "Add New... Measure" in the results bar ->select the measurement source (such as Ch1) ->select the measurement category (amplitude, timing, jitter, etc.) ->double-click the measurement item (such as "Peak to Peak"), and the measurement badge will be automatically added to the results bar.

Measurement configuration: Double click the measurement badge → Open the configuration menu, you can:

Label (for easy identification, such as "VCC peak to peak value");

Set reference level (such as 10% -90% rise time threshold);

Enable statistical display (mean, minimum, maximum, sample size);

Set measurement gating (only measure specific areas of the waveform, such as between the cursor and the screen display area).

(2) Core measurement categories and parameters

Application scenarios of key measurement items in measurement categories

Peak to peak value, maximum value, minimum value of amplitude measurement AC RMS、DC、 Analysis of positive/negative overshoot, top, bottom, and area voltage/amplitude characteristics (such as power ripple, signal amplitude consistency)

Timing measurement of frequency, cycle, rise/fall time, pulse width, duty cycle, delay, phase, data rate, and verification of unit interval signal timing characteristics (such as clock frequency, signal delay, duty cycle deviation)

Jitter measurement (basic) time interval error (TIE) preliminary jitter detection

Jitter Measurement (Advanced, requires DJA option) Deterministic Jitter (DJ), Random Jitter (RJ), Total Jitter（ TJ@BER ）Data related jitter (DDJ), periodic jitter (PJ), high-speed serial signal (such as USB, Ethernet) jitter compliance testing

Eye diagram measurement (DJA option required) eye height, eye width, eye height @ BER, eye width @ BER, Q-factor high-speed signal integrity assessment (such as SerDes, DDR)

(3) Bus decoding and analysis

Taking CAN bus as an example (requires 5-SRAUTO/SUP5-AFG options):
