The Tektronix TCP2020 rental Vietnam service from Lost in HCM gives engineering teams in Vietnam short-term access to this current probe, with sale and service options on request.

Tektronix TCP2020 rental Vietnam overview

The Tektronix TCP2020 rental Vietnam lets an oscilloscope show current as a clear waveform. So engineers can see inrush, ripple, switching edges, and fault pulses on screen. In addition, they can view current and voltage together on one timebase and link cause to effect.

This family covers Tektronix clamp probes, Rogowski loops, IsoVu isolated probes, and wideband current shunts. First, AC-only probes and current transformers capture fast pulses. Next, AC/DC probes add DC and slow changes. Finally, shunts pair with isolated probes for very fast switching work.

Tektronix TCP2020 rental Vietnam: measurement applications

Measure the current in a single conductor while observing its waveform on a compatible oscilloscope. This supports investigation of power-supply behavior, switching transients and load changes. Degauss and zero the probe before measurements, and select a range that accommodates the signal without exceeding pulse or continuous limits. Teams in Vietnam often choose Tektronix TCP2020 rental for this reason.

Illustrative connection diagram, not an internal service circuit. De-energize the circuit before fitting or removing the probe where required by the manual. Check conductor insulation, voltage category, jaw closure and current limits. Clamp around one conductor for its individual current; enclosing both supply and return can cancel their magnetic fields.

Setup and compatibility

The TCP2020 uses a BNC output, an external AC adapter and an input termination greater than 100 kΩ. Set current scaling on the connected instrument; this is not a direct TekVPI-powered model.

How the current probe works

An AC current probe works like a small transformer around the conductor. The changing magnetic field induces a signal in the probe core. Therefore, these probes read AC and pulse current well, but they cannot see DC or very slow changes. This applies to every Tektronix TCP2020 rental we arrange in Vietnam.

AC/DC probes add a Hall-effect sensor inside the core to track DC and low frequencies. Meanwhile, the transformer part handles the fast edges. As a result, one clamp covers DC to many megahertz, though it needs power from the scope, an adapter, or an amplifier.

What to look for in a current probe

Before you rent or buy, list the peak current, the fastest edge, and the conductor size. Then check whether you need DC. The features below explain what to compare, from bandwidth and range to interface, isolation, and safety ratings.

• AC only or AC and DC. AC-only probes and Rogowski loops skip DC, so they suit pulses and ripple. However, AC/DC models such as the TCP0030A and TCP303 also show DC offset, inrush, and slow load changes. So, plan it early when you book a Tektronix TCP2020 rental in Vietnam.
• Bandwidth and rise time. Bandwidth sets the fastest current edge the probe can follow. For example, the CT6 reaches 2 GHz, and the TICP100 reaches 1 GHz. Meanwhile, the A621 stops at 50 kHz, which suits mains work.
• Current range and peak limits. Check both RMS or continuous current and the peak pulse limit. For instance, the TCP404XL handles 500 A DC continuous, while the CT6 handles 120 mA RMS. Also, respect amp-second limits on long pulses.
• Scope interface and power. TekVPI probes such as the TCP0020 and TCP0150 draw power from a compatible scope. However, the TCP303 needs a TCPA300 amplifier, and the CT probes need a 50 Ω input. So confirm the full system first.
• Jaw size and loop fit. The probe must close around your conductor without strain. For example, the A621 takes conductors up to 54 mm, while the CT6 takes a 0.8 mm wire. Flexible Rogowski loops also wrap around bus bars and thick cables. Our Tektronix TCP2020 rental units in Vietnam ship ready for this kind of work.
• Isolation and shunt choice. IsoVu probes in the TICP family read current across a TICS shunt with galvanic isolation. Therefore, they suit high-side switching nodes. Shunt values from 5 mΩ to 5 Ω then set the current range and circuit loading.

Typical applications

Each application uses the probe to turn current into a waveform the team can measure. Then engineers compare that waveform with the design limits. Here is how labs, factories, and field teams in Vietnam use these probes and shunts every day.

• Power supply and inrush tests. Engineers capture inrush, ripple, and load steps on switch-mode supplies. So AC/DC probes like the TCP0030A show both the DC level and fast transients. As a result, teams confirm fuse and part ratings. Rental of the Tektronix TCP2020 is available across Vietnam.
• Motor drive and inverter checks. Drives and inverters switch high currents in each phase. Therefore, engineers use TCP303, TCP404XL, or Rogowski probes on the phase leads. Then they compare current with gate signals on the same scope.
• GaN and SiC switching analysis. Wide-bandgap devices switch very fast at high voltage. So teams pair TICP IsoVu probes with TICS shunts in the power loop. That setup measures switching current while the probe stays isolated.
• Battery and EV current profiles. Battery packs and chargers draw large DC currents that change with load. For example, high-current AC/DC probes record charge and discharge profiles. In addition, the data supports efficiency and thermal studies.
• Pulse and noise troubleshooting. Fast current pulses often cause noise and false triggers in a system. So compact current transformers such as the CT1, CT2, and CT6 capture short spikes on thin wires. Engineers then trace the noise to its source. Teams in Vietnam often choose Tektronix TCP2020 rental for this reason.
• Mains and power quality work. Facility teams check load current on mains wiring and panels. Therefore, large clamps like the A621 and A622 and flexible TRCP loops suit this job. Always follow the CAT rating on each probe.

Industries that use the Tektronix TCP2020 rental Vietnam

Any product that converts or switches power needs current checks at some stage. That is why probes and shunts appear in labs, factories, and field teams. Here is how each sector in Vietnam uses them in design and production work.

• Power electronics. Makers of supplies, chargers, and inverters in Binh Duong and Dong Nai validate switching current every day. So they keep AC/DC probes on design benches. They also rent isolated probes and shunts for new GaN designs.
• Automotive and EV. EV, e-motorbike, and component plants in Vietnam test drives, chargers, and battery systems. Therefore, they need high-current AC/DC and Rogowski probes. Portable setups also help when engineers work at the vehicle. This applies to every Tektronix TCP2020 rental we arrange in Vietnam.
• Electronics manufacturing services. EMS plants in Bac Ninh, Bac Giang, and Hai Phong measure board current during debug and failure analysis. As a result, compact AC/DC probes see daily use. Teams often rent extra units during production ramps.
• Renewable energy. Solar inverter and energy storage projects need current data on high-power converters. For example, flexible Rogowski loops wrap around thick cables and bus bars. Meanwhile, AC/DC probes check the DC link.
• Industrial automation. Factories run motors, drives, and servo systems that sometimes trip or overheat. So maintenance engineers use clamp probes to read phase current at the machine. This helps them find overload and imbalance faults.
• Education and research. Universities and research labs in Vietnam teach power electronics with hands-on tests. Therefore, they need safe, reliable current probes for many benches. Rental helps them equip a lab for one course or project. So, plan it early when you book a Tektronix TCP2020 rental in Vietnam.

Tektronix TCP2020 rental Vietnam compared with other brands

Several makers build current probes for their own oscilloscopes and for general bench use. Each takes a different path on bandwidth, current range, and interface. The rows below show where the Tektronix TCP2020 rental Vietnam sits among other common choices on the market.

Start with the current range and bandwidth your circuit really needs. Next, check DC needs, jaw size, isolation, and how the probe connects to your scope. Finally, confirm current specs with each maker, because product lines change over time. Specifications change, so confirm current data with each maker before you decide.

Rent or buy?

Rent a current probe for a design validation, a failure analysis, or a short power study. Rental also gives access to high-current probes, IsoVu systems, and amplifiers for one project. Then you return them, so capital stays free for other test needs.

Selection tips

• Choose AC/DC when you need DC levels, inrush, or slow changes. Otherwise, an AC-only probe or a Rogowski loop may cover pulses and ripple well.
• Match bandwidth to your fastest current edge, not just the switching frequency. So fast GaN or SiC edges may need an isolated probe and shunt instead of a clamp. Our Tektronix TCP2020 rental units in Vietnam ship ready for this kind of work.
• Check peak, RMS, and continuous current limits together. Also review the amp-second limit for long pulses, because going past it can saturate the core.
• Confirm how the probe connects, such as TekVPI, BNC, or a separate amplifier. Then make sure your scope supports that interface and the needed input impedance.
• Measure the conductor or bus bar before you choose a jaw or loop size. For instance, thick cables may need a large clamp or a flexible Rogowski loop.
• For a shunt setup, pick a resistance that gives a usable voltage at your current. However, a higher value adds more loading and heat to the circuit.

Handling and care

• Close probe jaws gently and keep the core faces clean, because dirt adds error. Also store each probe, amplifier, and shunt in its case between jobs. Rental of the Tektronix TCP2020 is available across Vietnam.
• Respect the voltage and CAT rating on every probe, since bare conductors can carry hazardous voltage. In addition, wear an ESD strap when you handle IsoVu tips and shunts.
• Let AC/DC probes warm up for the time the maker states. Next, degauss and zero the probe before precise DC readings, and repeat after any overload.
• Follow the calibration interval each maker states, which is often one year. Rental units ship with a valid calibration certificate, and we can arrange service through the maker or an authorized partner.
• Ship probes in padded cases with cables coiled loosely and jaws closed. In addition, keep them dry during Vietnam's humid wet season, because moisture harms sensors.
