Tektronix TPS2000 series digital storage oscilloscope

Window selection function (Hanning window: excellent frequency resolution; flat top window: excellent amplitude accuracy).

De aliasing method:

Increase sampling rate (switch from SEC/DIV to faster gear);

Enable 20MHz bandwidth limit;

External filtering (adding a low-pass filter at the signal source end).

Battery Management (Core Features)

1. Charging and battery life

Charging method: single battery charging time, dual battery charging sequence, battery life (4-channel model)

In machine (power on), charge the high battery first for 7 hours, then charge the low battery for 4.5 hours (single battery), and 9 hours (dual battery)

In machine (standby) 4.5 hours as above-

External TPSCHG charger can charge 2 units simultaneously in 3 hours-

2. Calibration and maintenance

Calibration:

External calibration: TPSCHG charger left slot → press "Recalibrate", takes about 10 hours (charge discharge cycle);

In machine calibration: discharge to shutdown → charge for 5 hours → discharge to shutdown → recharge for another 5 hours.

Storage:

Temperature: 5-20 ℃, humidity ≤ 80%;

Electricity consumption: about 50%, replenished once every 6 months;

Taboo: Long term full charge (>80%) or empty charge (<20%) storage is prohibited.

Data Storage and Communication

1. CompactFlash card operation

Storage Content File Name Format 1MB Capacity Approximately Storage Quantity Key Operations

18 waveform files FnnnnCHx.CSV, press 【 Save/Recall 】 → 【 Save Waveform 】 → Select Channel

Set file FnnnnTEK.SET to 250, press 【 Save/Recall 】 → 【 Save Setup 】 → select storage location

16 image files FnnnnTEK.BMP, press [Print] (set to "Save Image to File")

2. RS-232 communication settings

Parameter configuration: Press 【 Utility 】 → 【 Options 】 → 【 RS232 Setup 】 to set the baud rate (default 9600), flow control (Hardtagging), and checksum (None);

Test steps:

Connect the oscilloscope to the PC using cable 012-1379-00;

Open HyperTerminal on the PC and set the same parameters;

Send 'ID?', the oscilloscope returns' ID TEK/TPS2024, CF: 91.1CT, FV: V10.00 '.

Typical application cases

1. Isolation channel measurement differential signal

Connect the probe tip to the positive terminal of the differential signal and the reference terminal to the negative terminal (no common ground required);

Press' AutoSet 'to display the differential waveform;

Press' Single Seq 'to capture a snapshot, and use the cursor to measure the amplitude/rise time.

2. Video signal triggering (NTSC)

Connect the probe to video output, press 【 CH1 MENU 】 → 【 Coupling 】 → 【 AC 】;

Press 【 Trig Menu 】→【 Type 】→【 Video 】→【 Standard 】→【 NTSC 】;

Select [Sync] → [All Lines], adjust SEC/DIV to 500ns/div, and observe the color synchronization signal.

3. Power waveform measurement (voltage x current)

CH1 connected to voltage probe (10X), CH2 connected to current probe (10A/V);

Press 【 Math Menu 】→【 Operation 】→【 × 】→【 CH1 × CH2 】;

Adjust the Math waveform position/scale to display instantaneous power (in VA).
