Safety operation standards

1. Electrical safety

Grounding requirements: A 3-pin power cord must be used, and the grounding conductor must be connected to the ground. It is forbidden to disconnect the grounding

Voltage limitation: The maximum voltage of the input channel is 300V RMS CAT II, and when it exceeds 100kHz, it attenuates by 20dB/tenfold

Probe safety: When using TPP series probes, fingers should be placed behind a protective barrier and touching the metal parts of the probe is prohibited

2. Operation taboos

Prohibited from use in damp/explosive environments, avoid liquid spraying equipment

It is prohibited to dismantle the equipment casing as high internal voltage may cause electric shock

When connecting/disconnecting the probe, the signal source should be disconnected first to avoid arc damage

Basic operation process

1. Equipment installation and functional inspection

Power connection: Connect to a 90-264VAC/45-66Hz power supply, with a maximum power consumption of 30W

Secure fixation: Fix equipment through safety lock holes or cable channels to prevent slipping

Functional check:

Press' Default Setup 'to restore factory settings

Connect the probe to CH1, and connect the probe tip to the PROBE COMP terminal（ 5V@1kHz Square wave

Press [Autoset], the screen should display a stable square wave, and the calibration status should be "PASSED"

2. Probe operation

Manual compensation:

Probe connected to CH1, set attenuation to 10X

Connect the probe tip to [PROBE COMP] and press [Autoset]

Adjust the probe compensation hole to make the square wave edge straight (to avoid overcompensation/undercompensation)

Attenuation setting: default 10X, P2220 probe supports 1X/10X switching (bandwidth limited to 6MHz at 1X)

Current probe: The scaling ratio needs to be manually set (default 10A/V) to ensure accurate readings

3. Self calibration and firmware updates

Self calibration:

Trigger condition: If the environmental temperature difference exceeds 5 ℃ or once a week, preheating for 20 minutes is required

Operation steps: Disconnect all probes → 【 Utility 】 → 【 Do Self Cal 】 → Follow the prompts to complete (about 2 minutes)

Firmware update:

Download the latest firmware from the official website (www.tektronix. com/software)

Copy to the root directory of the USB flash drive and insert the oscilloscope

[Utility] → [File Utilities] → [Update Firmware] → Wait for completion

Core System and Control

1. Vertical Controls

Coupling method:

DC: Transmitting AC+DC signals, suitable for measuring signals with DC offset

AC: Block DC components, suitable for observing AC signals

GND: Disconnect input, display 0V line, used for calibrating ground reference

Bandwidth limit: 20MHz bandwidth limit can be selected to reduce high-frequency noise

Voltage/grid adjustment: Range 2mV-5V/div, supports coarse adjustment (1-2-5 sequence)/fine adjustment (small step size)

2. Horizontal Controls

Time base range:

30MHz model: 10ns-50s/div

50/70MHz model: 5ns-50s/div

100/150/200MHz model: 2.5ns-50s/div

Scanning mode: automatically turned on when the time base is ≥ 100ms/div and the trigger mode is "Auto", and the waveform scrolls from left to right

Zoom function: Press [Zoom] to zoom in on specific parts of the waveform, supporting X1/X2/X5/X10 zoom ratios

3. Trigger Controls

Trigger type key parameters applicable scenarios

Edge triggered slope (rising/falling), coupling (AC/DC/noise suppression), stable display of conventional signals (sine wave/square wave)

Video trigger standards (NTSC/PAL/SECAM), synchronous (field/line) composite video signal testing, such as television signals

Pulse width triggering conditions (=≠<>), width (33ns-10s), polarity (positive/negative) capture abnormal pulses (such as spikes, narrow pulses)

Trigger mode:

Auto: Automatically scans without triggering, suitable for signal exploration

Normal: Only displayed when triggered, suitable for stable signal observation

Single: Single capture, suitable for transient signals (such as relay arcs)

4. Acquisition Controls

The working principle of the collection mode is applicable to different scenarios

Sampling mode equidistant sampling, 1 sampling point=1 waveform point for most conventional signals

Peak detection mode records the maximum/minimum values within each interval, captures narrow pulses (≥ 10ns), and reduces aliasing

After multiple acquisitions in average mode (4/16/64/128 times optional), suppress random noise and improve signal clarity

Measurement and analysis functions

1. Basic measurement techniques

Voltage measurement:

Peak to Peak Value (Vp-p): The difference between the maximum and minimum values of the signal, calculated by multiplying the number of vertical partitions by volts per grid and the probe attenuation ratio

Amplitude: Voltage from ground to signal peak, for example: 2V/div x 3 zones x 10X probe=60V

Time measurement:

Cycle/frequency: Cycle=number of horizontal partitions x seconds/grid, frequency=1/cycle

Pulse width: time interval at 50% amplitude, rise/fall time: time interval at 10% -90% amplitude

Phase difference measurement: Turn on XY mode and use the Lissajous diagram to determine (for example, when the frequency ratio is 1:1, the straight line is 0 ° and the circle is 90 °)

2. Automatic measurement and FFT analysis

Automatic measurement:

Supports 34 types, including time class (cycle, frequency, delay), amplitude class (peak to peak, overshoot), and count class (pulse number, edge number)

Up to 6 measurement results can be displayed simultaneously, with an update frequency of approximately 2 times per second

FFT analysis:

Window function selection: Hanning window (excellent frequency resolution), flat top window (excellent amplitude accuracy), rectangular window (transient analysis)

Nyquist frequency: half of the sampling rate. Exceeding this frequency will result in aliasing, which needs to be resolved by increasing the sampling rate or filtering

Spectrum measurement: supports cursor measurement of frequency (Hz) and amplitude (dB, 0dB=1VRMS)
